Dear All,
I made a program in C++ and i want to call it into C#.
How can i call it.
Thanks

Can you be a little more specific?

Is your program compiled to a DLL? If yes, you can reference the DLL and call any function in that dll file as an 'external' function from C#. (To access native win32 functions from the windows dlls for example).

you can call any .exe file using shell function shell(.......................)

ehh... why not simply using Process.Start?!

why don't u use process.start("file.exe", "arguments");

Hi. Is the program managed or unmanged? Managed programs can be added to .net refrences like Managed assemblies can. If its COM, you can access it by adding a COM refrence. If its a standard Windows DLL, you should follow peoples suggestions above.
