Call a function of DLL (written in VC++) from C#

Question

I have a DLL written in VC++ and I need to make use of the functions (available in DLL) in my C# Forms application. Tried using the export features available but nothing worked for me. Also I tried other possible solutions that I managed to get by browsing like the wrappers, p Invoke etc. Will be thankful if someone suggest a good working solution.

Answer 1

If your C++ code is generated as native code you can use the DllImportAttribute.

[DllImport("yourdll.dll")]
public extern returnType FunctionName (int p1, string p2); // the parameters are the same as the C++ function
