C# - Finding All Namespaces In An Assembly Using Reflection (DotNET)
Oct 10, 2009
I've got an assembly (loaded as ReflectionOnly) and I want to find all the namespaces in this assembly so I can convert them into "using" ("Imports" in VB) statements for an auto-generated source code file template.
Ideally I'd like to restrict myself to top-level namespaces only, so instead of:
using System;
using System.Collections;
using System.Collections.Generic;
you'd only get:
using System;
I noticed there is a Namespace property on the System.Type class, but is there a better way to collect Namespaces inside an assembly that doesn't involve iterating over all types and culling duplicate namespace strings?

I would like to load a class library at runtime. As such, I thought I could use reflection to do so.However I am receiving the exception "Unable to cast object of type 'MyLibrary.LogSystem' to type 'MainApp.ILog'." in my main application. To start with I created a Class Library (VS2010) with a simple interface and one class that implements the interface.

I have a self-generated code in one assembly which in some of the lines includes properties, I was wondering how can I retrieve them? Especially when that class is a view object and does not contain any parameters so we can do it by data adapter and finding for example insert or update parameter.

i am writing a simple games client using an XNA 2.0 engine to play games. The games are written in dll files and the client uses the assembly.loadfrom method to read and execute the games accordingly...Now this all works fine on my computer and my laptop. However when i give it to my friend he gets this error and the dll doesnt load - "Unable to load one or more of the requested types. Retrieve the loader exceptions property for more information"

I'm trying to find the public delegates contained within a bas module in an assembly. I can identify the bas module, find nested types, methods, etc. but there seems to be no way to get nested delegates.
Note: 'GetNestedTypes' does not return delegates for bas modules.

I want to use reflection to dynamically call a dll (not an assembly, non-managed, possibly COM object model) in vb.net.I've seen several different methods of calling a method in a dll that is a .net assembly - but I have not found the way to dynamically call a method inside of a dll like user32.dll or winmm.dll. I believe this would be called late-binding?
The reason I'm asking is because I am building a language that will depend on external libraries for lots of different functionality. An example (in this language I'm building):
Declare Function mciSendStringA using "winmm.dll" (strCommand As String, strReturn As String, returnLength As Integer, blah As Integer) As Integer
Declare Function WriteConsoleA using "kernel32.dll" (hConsoleOutput As Integer, lpBuffer As String, numberofcharstowrite as Integer, lpReserved as Integer) As Boolean
When I build the interpreter for the call to mciSendString in winmm.dll, how can I use reflection to handle this? I want the user to be able to reference any dll/method they wish.Can I get some guidance in the right direction? Perhaps even some vb.net code that I can take apart and understand?

Our company has an app that load their components by System.Reflection.Load (By the way, an awesome technique )But, we start to monitorate the application and detect a extrange grow up of memory (actually when our application still all day on air, their allocate memory on task manager is 200 MB plus memory) And all of our components (60 plus DLLs) is load by this technique.My doubt is how to deallocate this assemblies or how the best way to deallocate any assemblies loaded by the System.Reflection.Assemblie.Load method?

I have a solution with two projects within:
Company.Project.vbproj
Company.Project.Tests.vbproj
Within the Company.Project.vbproj assembly, I have a class FriendClass.vb which scope is Friend (internal in C#).Now I wish to test this FriendClass.vb from within the Company.Project.Tests.vbproj assembly. I know about the InternalsVisibleToAttribute, but that is not an option in Visual Basic .NET 2.0, as it is only available with C#, in .NET 2.0 (see here).I would like to create myself a proxy class using this internal FriendClass from within my testing assembly, so that I could instantiate it and do the testings accordingly.

When running setup to install published program, the following message occurs: System Update Required: Unable to install or run the applicaiton. The application requires that asssembly CrystalDecisions.CrystalReports.Engine Version 10.2.3600.0 be install in the Global Assembly Cache (GAC) first. This version is listed in the references of the program and in my mind, be included in build. How do I get by this error?

I am loading an Assembly using Assembly.LoadFrom() as the assemblies are located in a different path from Application Base directory.
Dim oAssembly As Assembly = _
Assembly.LoadFrom("C:\MyFolder\" + ddlXlate.SelectedItem.ToString() + ".dll")
And I consume a Type from that assembly without any problem:
oXML = CType(oAssembly.CreateInstance(sBaseType + ".XlateContainer"), _
XlateBase.XlateContainer)
However, the problem occurs when I try to use a Type from this assembly from within another method like the one below:
oComboBox.DataSource = _
[Enum].GetValues(Type.GetType(sType + "+ItemEnum," + sAssemblyName))
sAssemblyName is the one I loaded using LoadFrom() actually. After it said it cannot find the assembly, I used AssemblyResolve event which solved my problem :Subscribing AssemblyResolve event :
AddHandler AppDomain.CurrentDomain.AssemblyResolve, _
AddressOf MyResolveEventHandler
Event Handler Method:
Private Shared Function MyResolveEventHandler(ByVal sender As Object, _
ByVal args As ResolveEventArgs) As Assembly
Return Assembly.LoadFrom("C:\PSIOBJ\" + args.Name + ".dll")
End Function
And I thought maybe the error occurs because it cannot find a dependent assembly defined in assembly manifest file I loaded using LoadFrom() already but when I checked the args.Name, I saw it was trying to load same assembly and after that it worked without any problem. So basically a type in the loaded assembly cannot be found before the event adding change.
My old code was using AppDomain.CurrentDomain.Load() and Assembly.Load() methods and they were working fine without the AssemblyResolve event. I was able to reach types in dynamically loaded Assembly from every where within the same AppDomain.
LoadFrom() can find dependencies automatically within the same requested assembly path and that couldn't be problem as everything this dll needs was there. So at first it looked like a AppDomain problem to me as it looks like it seems it can reach assemblies from Load context instead of LoadFrom context and I am now using LoadFrom context.But now it seems I should pass oAssembly instance evertwhere to use any type from the loaded assembly?Doesn't it load the assembly where I can reach it everywhere (same AppDomain) using simple Type.GetType(...) method?

I'm wanting to include a system tray icon in my WPF project, and found this resource:[URL]..which looks like it will work beautifully, but it's written for C# and I'm using VB.net for this project. I downloaded his project and built the notifyicon as a DLL, then added as a reference to my project.
It throws up an error: Unable to emit assembly: Referenced assembly 'Hardcodet.Wpf.TaskbarNotification' does not have a strong name So I'm trying to figure out the best way to proceed. Do I need to strong name it, or is there a better way to do this?

I have created several DLL (.NET) libraries that are used in several projects. In these DLL libraries I want to know/retrieve which assembly (EXE) calls/uses the library, so if possible I want to know info like assembly name (EXE), strong name, version number, etc.
NB: Examples may be in C# or VB. I use both languages.

I have written a .net assembly which plugs into to a third party COM application. The .net assembly is COM visible to the third party application. However this .net assembly references other regular assemblies. If I put these assemblies in the GAC the COM visibile assembly sees them without a problem. However for various reasons I do not want to put them into the GAC but I cannot get my COM visible assembly to see the other assemblies when they are in other locations. I have tried putting them in the same directory as the COM visible assembly. I have tried putting them in the same directory as the third party app's exe but neither of these work.

Since, it's possible for anyone to name an assembly starting with 'System', checking for 'System' is not a satisfactory solution.
Alternatively, if that's not possible, how about checking the modules in an assembly?

I am building a dll-Assemby A which references another Assembly B. Assembly B is strongly named and installed in the GAC of my development computer. An other computer will not have assembly B installed in the GAC.
Question: If i handle strongly named assembly B like a private assembly and copying it into the bin-directory by specifying local copy = true in the properties-window, will the programm run on the other computer?

One of them is giving us trouble in only 1 spot out of the 4 spots we use it at:The trouble spot is a windows form project that uses reflection to dynamically load some DLLs that run long running processes. One of these long running processes is an agent that relies on one of our vender DLLsWe're getting the missing assembly exception at the point where we first enter a function that references the library. I already checked the silly things such as if we had forgotten to move a reference from the old version to the new version, but that's not the case. I also checked the bin directory of the project and the assembly is there.

I'm looking at a small remoting project in VB.NET. Initial research turns up references to msrdp.ocx which my Windows 7 Ult system doesn't have; a filesystem search on the same platform turns up MsRdpWebAccess.dll which doesn't appear to be well documented; finally hunting through COM references in Visual Studio turns up rdpencom.dll labeled "rdpcomapi 1.0 Type Library" which seems to be best documented via personal developer blogs (which isn't encouraging but is a lot better than other options).
My goal is a lightweight remoting application I can deploy to Windows 2000 Client/Server, WinXP x86/x64, Win2k3 Server, Vista x86/64, and Win2k8 Server.Is there anything DotNET Native I can use instead of one of these COM libraries? Is one of these COM libraries better for the job overall than others; and then am I going to have platform-specific compatibility issues if I don't provide support for more than 1 of them in my app?

I would like to download a file using VB.NET (preferably) or C# via HTTPS.
I have this code to download a file over plain HTTP:
Dim client As WebClient = New WebClient()
Dim wp As WebProxy = New WebProxy("[IP number of our proxy server]", [port number of our proxy server])
wp.Credentials = CredentialCache.DefaultCredentials
client.Proxy = wp
client.DownloadFile("http://sstatic.net/so/img/logo.png", "c:logo.png")
How do I change this code to download a file that is stored on an HTTPS-server? I guess it has something to do with adding credentials or something.
