How would you convert this to VB (using .NET 4.0 / VS2010) ?
bw.DoWork += (o, args) =>
{
Code Here
};
I thought maybe like this:
AddHandler bw.DoWork,
Function(o, args)[code]....
But it says Function does not return a value on all code paths.

There are two ways to create methods on the fly. Through Anonymous method and through Lambda expression (relevant for C# language as far as i know). Though there is not much difference between them. How to create Anonymous methods in VB.NET ?

I'm trying to create an extension method that returns an IEqualityComparer based on a lambda function. Heres the extension method:
<Extension()>
Public Function Comparer(Of T)(Func As Func(Of T, T, Boolean)) As IEqualityComparer(Of T)
Return New GenericComparer(Of T)(Func)
End Function

With C# anonymous delegates, we can avoid declaration of extra method, I know in VB.NET they're not available, but is there a design pattern that I can use so that I can avoid writing an extra method each time? I need it for SPSecurity.RunWithElevatedPrivileges which will be used a lot of times in our code.

(using VB 08!) In order to avoid "magic strings", I have used this handy method (not my own!) many times to get a property's name as a string:
Function GetPropertyName(Of T, R)(ByVal expression As
Linq.Expressions.Expression(Of Func(Of T, R))) As
String

I found that this answer was asked and answered before VS2010 was actually released.[code]to a .NET Framework 4.0 project in Visual Studio 2010 and it does not compile.Do you now if this feature is really implemented and what I am doing wrong?

public static string CalculateSHA1(string text, Encoding enc)
{
byte[] buffer = enc.GetBytes(text);
SHA1CryptoServiceProvider cryptoTransformSHA1 = new SHA1CryptoServiceProvider();

VStudio keeps yelling at me for just what I have so far most specifically the bracket at the end of Byte?:
Private Sub CalculateSHA1(ByVal text As String, ByVal enc As Encoding)
Dim buffer As Byte[] = enc.GetBytes(text);

I've been trying to figure out how to do this for some time now and keep coming up short, so I'm hoping to get some good suggestions.
I'm making an application that will allow the user to add some labels during runtime, edit their text, and then 'build' the designer that would output code for a scripting language.
The people using this app are creating the scripts using Notepad++ at the moment, but aren't developers in any way and would like an easier, point and click method.[code]...

i want to extend the integer class to a method that increments current integer value by 2. I create a console application and a second module which contains the extension method.
Imports System.Runtime.CompilerServices
Module StringExtensions
<Extension()>
[code]....
and everything works fine. The extension method module can be imported to any other project (Project-->add existing item --> select the vb file that contains the extension method module) and works fine too. But the code is accessible to other users. Is there a method to convert the extension method module to a dll and adding it to other projects as a reference. I tried to do it with creating a class project and pasting the code of the extension method module and compile the dll and then added it as reference to another project and imported the class with the keyword imports, but it didn't work.

I have some files in vb.net that have "Option Strict Off" to allow for bad programming. When I convert to c# I use "dynamic" until I come back and fix problems, and this works in all cases But now I have this code:
Public Class ContractResults
'Big class definition
Public Shared Sub CleanCache()
[code].....
And in a file with Option Strict Off:
Public Sub VerifyResults(result as Object)
'Here, result is normally ContractResults
'first it check for that then call this:
result.CleanCache()
End Sub
In c# I use "dynamic", but a runtime error pops up when I call "static" method with dynamic reference. In vb.net, I can called "shared" sub from instance, but in c# this is not allowed
Exception:
"Microsoft.CSharp.RuntimeBinder.RuntimeBinderException"
"Member 'ContractTypes.ContractResults.CleanCache()' cannot be accessed with an instance reference; qualify it with a type name instead"
It seems I must convert code to use actual type, but then this means much rewriting of more parts. Is anyone able to show another way?I want to make sure you do not think I can use (result as ContractResults).CleanCache();Because all types that may be passed in have "CleanCache()" method, but do not inherits from anything the same other than "Object". There are many types (30!) that have this "static" method and so that is why it uses Option Strict Off?

I am sure i am doing something terribly wrong, but i should better ask the experts.
At the third line i get the error Value of type <anonymous type> cannot be converted to <anonymous type>

Dim v = New With {.Amount = 108}

The following syntax is valid VB.NET code
Dim myCollection As New List(Of Stock)
myCollection.Add(New Stock(Guid.NewGuid, "Item1"))
myCollection.Add(New Stock(Guid.NewGuid, "Item2"))
[code]....
How can I accomplish the same thing in C#? I have tried...
myCollection.FindAll(bool delegate(Stock stock) {
if (blah blah) {
}
});
But it appears I have somehow structured it incorrectly as I get the following error. "Error 1 Invalid expression term 'bool'"

Are anonymous types slower than declarative types?
For example, does
Dim score as Double = CalculateScore()
run slower than
Dim score = CalculateScore()
Why use explicit typing if it's no slower?
