Dear All,
How I can call a method of C# class from VB.Net? Suppose I have a
class SaveFile in C# having a method saveImageFile(). There is a form
Form1 in VB.Net having an picturebox populated with an image. I want
to call SaveFile.saveImageFile() method from Form1. How it will be
done?

Regares,
Arif

Is your C# code available in a separate DLL? What you do then is add a
reference to that particular dll. After having set that reference you simply
invoke the C# function with its name + expected parameters from VB.NET, e.g.
SaveFile.saveImageFile().

You can also add the C# project to your Solution

Add your C# class to a class library project, compile it and then
reference the assembly from your VB .NET project. Very simple, yet
effective.

Dear Milosz,
Yup, I can add C# project to my solution but how i can use it? The C#
namespace is not accessible in VB.Net project.

Arif

Dear Neil,
I have compiled my C# class library and add it to VB.Net project. When
I rebuilt the solution of VB.Net project, I gave an error that
application conflict with "mscorlib.dll". I dig out this file from my
computer and placed it with my application and start the error was
resolved.
But when my other team member took the latest version of application
and compiled VB.Net project, he also got the same error and it is not
be resolved in any case.
What would be the problem with this?

Regards,
Muhammad Arif

In this case, you need to add a reference to the C# project to your VB
..NET project.

Are you using the .NET CF version of mscorlib? It has a public key token
of 969db8053d3322ac.

Quite simple. Compile your C# class into a Dll and Add Reference to it
from your VB project and then, declare a type of the C# class
programmatically and instantiate it.

Dim o as Class1
o=new Class1
o.saveImageFile()

Dear Neil,
I how i can judge that I am using .NET CF version of mscorlib?
Moreover, for what purpose this library is used?
