Dynamic Library loading..

[VJ]

I will have the path of a DLL i.e C:\Test\Test.dll and a Method name in the
DLL say ExecuteMe(string arg1, int arg2). I want to be able to load the DLL
at run-time and execute this method. I also want to be able to capture the
return value of the Method.

Vijay,

Is this an unmanaged DLL that exports a C type function, or is it a
managed DLL? The ways you would do this are very, very different.

 

[VJ]

Nicholas, it can be both, for now I would like to know only for managed
DLL's

VJ,

For managed DLL's, you would use reflection (assuming that the types you
are loading don't implement a common interface which you have access to).
You would get the Type instance, and from there, you can get method/property
information, from which you can get the value or invoke the method.

Vijay,

First of all you should load the assembly and get a reference to it, take a
look at:
