Self-referencing Current Type's Name (static Version Of Me/MyClass)?

Mar 16, 2010

Traditionally, class/type name is literally spelled inside its definition.

Public Class MyCustomClass
Public child As MyCustomClass
Public Shared Function Clone(ByVal original As MyCustomClass) As MyCustomClass
End Class

This is not a problem most of the time; C-languages even use class name as constructor methods' name. But consider a generic declaration:

Public Class MyListOfIntegers
Inherits MyCustomList(Of Integer)
End Class

[code]....

This scenario has 2 issues. The first one is that constructors are not inherited, and you have to provide pass-through wrappers in every derived class, — this is quiet dumb, but tolerable. The second issue is more severe: derived class inherits CloneMe() method which returns MyCustomList(Of Integer) , not MyListOfIntegers ! Every returned value must be manually DirectCast 'ed for further use with methods that expect MyListOfIntegers . This issue, together with the first one, renders inheritance of generic class almost useless.

So I need a "MyClass" alternative for static type-binding inside type definition. In case of generic type that is referencing other compound types, task could be accomplished by adding second parameter to type section:

Public Class MyCustomList(Of T, TList)
...
Public Function CloneMe() As TList

[code]....

But since we must reference our own type, it would create an infinite recursive loop of additional typeparamlist arguments. How can this be resolved, aside of creating separate classes without generics?

Ombine Two Linq Expressions Of A Custom Type (i.e. Expression(Of Func(Of MyClass, MyClass))

Nov 24, 2010

I have a list of properties and values that i'd like to use to dynamically build an Expression(Of Func(Of MyClass,MyClass))

I can run through the list and create each Expression by itself, but the only way I know how to combine them would be to use Expression.And or Expression.AndAlso, but that returns a BinaryExpression rather than my original Expression(Of Func(Of MyClass,MyClass)).

C# - Why Only Static / Shared Version Of ForEach For Arrays

Aug 18, 2011

Why there is only a static/shared version of ForEach for arrays?
IE: ForEach<T>(T array[], System.Action(Of T) action[])
I assume this has something to do with the type inference requirements of implementing an instance method, but when you declare your array you provide type right?

IDE :: Auto-Referencing Latest Version Of Assembly

Feb 23, 2009

We have one program that acts as a "server" (so to speak) and many programs that reference it. every time we update the server, we are forced to update all the dependent programs to reference the new version number. Our IPC communication protocol is pretty stable and doesn't change, so we aren't worried about upgrade incompatibilities. I would like to know how to automatically reference the "latest" version of an assembly. What I mean is, if I choose Project->properties->references, I always get a specific version. Is there a way to reference whatever the latest version is? This way, we wouldn't have to update every program that is dependent on our server every single time there is an update.

IDE :: Why System.dll Is Not Referencing The Latest .Net Framework Version

Apr 25, 2010

I have a VS2010 solution (upgraded) that has two projects, an EXE and a DLL. In both the Target framework versions are 4.0. When one look at the references of the EXE project, one can see that the System.dll (and System.Core.dll and so for) references to the v4 version (the latest); however, in the DLL project the references points to the .Net Framework v2 version. Why is this happening? How can I make all my projects to point to the v4 libraries?

IDE :: Assembly Version, File Version And Publish Version In ClickOnce In VS 2008

How they relate and differ from each? What are the best practices for version control? Is there a primer about publish online? Or a good book?

And is it possible to make ClickOnce and a msi in one solution of VS 2008? If so, is there any conflict or pitfall?

BTW I am using VB if that makes any difference.

MyClass Equivalent Behavior In C#

Jul 26, 2011

The MyClass keyword behaves like an object variable referring to the current instance of a class as originally implemented. MyClass is similar to Me, but all method calls on it are treated as if the method were NotOverridable. I can see how that could kind of be useful, in some specific scenarios. What I can't think of is, how would you obtain the same behavior in C# - that is, to ensure that a call to a virtual method myMethod is actually invoked against myMethod in the current class, and not a derived myMethod (a.k.a in the IL, invoking call rather than callvirt)?

.net - Can A Generic Version Of A Derived Class Override A Base Method Using The Generic Type

Apr 13, 2012

Consider:

Public MustInherit Class Column
Public ReadOnly Property ReturnSomethingUseful() As Object
Get
'return something useful

[code]....

But this gives the following error:

Public Overrides Function ParseValue(sValue As String) As Boolean'
cannot override 'Public Overridable Function ParseValue(sValue As String) As Object'
because they differ by their return types.

I accept that you can't do this, but I'd like to be able to preserve the semantics of what I'm. trying to do, which is to have an untyped version that deals with Object, but a typed version in derived classes that knows about the specific type T.
