Using a VB6 Class in C#

Question

是否可以在C＃中使用VB6类？

Answer 1

I think you should just be able to add the library that contains your VB6 type as a reference in your C# project. Visual Studio will create an Interop Assembly on the fly, and you'll get access to all of the types in the VB6 library via Runtime Callable Wrappers .

The tool that creates the Interop Assembly is TLBIMP.EXE , and you can run this yourself if you want more control over the process, eg. if you want to create a Primary Interop Assembly that might be shared by multiple managed components.

Answer 2

You can use a compiled VB6 dll in a C# program by using COM Interop.

If you have the VB6 source and the funding, I would recommend you to rewrite the class in C#.

当然，你只需要把它变成一个COM对象。
