Re: Adding C#-Code to VB-Project in VS 2005 without using DLL

Now there's a question and a half Seth :)

Have you finished the preprocessor yet? :)

How would you envisage it resolving something like:

#Visual Basic

Public Class Foo

#End Visual Basic

#Visual Basic

Public X As Integer

Public Sub VBFoo

x += 1

End Sub

#End Visual Basic

#CSharp

public int x;

public void CSharpFoo()
{
x++;
}

#CSharp

#Visual Basic

End Class

#End Visual Basic

In VB.NET, variable names are case-insensitive, so, logically the dummy would be spat because VB.Net can;t handle 2 variables with the same name having the same scope.

In C#, however, variable names are case-sensitive, so, X and x declared having the same scope is perfectly legal.

The point here is that such a preprocessor, to be of any value would need to break the rules of one language to allow the rules of the other language, and, immediately, that need negates any value that such a preprocessor might have.

I know this is slightly off topic, but I'm curious - since both vb and
c# compile to msil, why couldn't the ide use a preprocessor to support
different languages in the same file?

Something like:

#Visual Basic
Public Sub VBFoo()
...
End Sub
#End Visual Basic

#CSharp
public void CSharpFoo( )
{
...
}
#End CSharp

Thanks,

Seth Rowe

You actually cannot, except in Web projects in which you can use different
languages in different script blocks and pages.
