i have a dll with its .h file,in the .h i found the [ extern "C" ] .
when i tried to add the dll to a c# app ,it give me that error
[please make sure that it is a valid com or assembly component]

You can't add a "native code" dll to a C# project, C# cannot statically link to DLL's . If
you need to call "C" style functions exported from DLL's from C#, you'll have to import the
functions using the DllImport attribute. Search MSDN for details on PInvoke and DllImport.
