[lingchen_email]

Hi,

Is there a way to call an API in unmanaged DLL from C# application in a
way that the name of the API is generated programmatically?

For example, I have API_AAA(p1,p2) & API_BBB(p1,p2,p3) defined in an
unmanaged DLL already. I know that I can use DllImport and declare the
APIs as "public static extern ......", and then call API_AAA() &
API_BBB() directly from the C# code. But, what I really want is
something similar to Type.InvokeMethod() in C# so that I can call
either API_AAA() or API_BBB() by passing the function name in string
programmatically to the Invoke() call, and also generate the
corresponding parameter values dynamically into an args array.

Is this possible?

Thanks,
LingChen

Take a look at the TypeBuilder class in System.Reflection.Emit.
