Question

Thanks

Answer 1

Compile the C# class in it's own C# class library (DLL) and then in your VB project, add a reference to the C# DLL. You can then use the class in your VB project.

If, however, you want to include the source code of the C# class in your VB project then you will have to convert the class from C# to VB. There are various methods of doing this, such as the online tool Convert C# to VB.NET

Answer 2

It is very simple to combine your VB.net & C#.net project.

Step1- Add projects which you wanna combine to a single solution.

Step2- Within any one project VB/C# in which you want to call classes from other language project "Goto- Add Reference- Projects" and select the other project which will be automatically displayed.

Step3- After adding the reference just add "Imports (in VB)" or "using (in C#)" statements to your code.

Step4- bingooo!!! now you can use your VB/C# classes in another language.

(tip: You can go only in one direction here i.e. either you can use your C# classes in VB.net or vice versa.)

All the best

You can also add the reference for an executable, if it is a .NET assembly. So just compile your C# project and add it as reference into your VB project.
