Hi,

I have an address which points to the entry point of an
application. Now using the same address i want to call
this function again, how do i convert this pointer which
is of type System.IntPtr into a function pointer?

Regards,
Manoj Pandole

Pre-Whidbey you can't. You have to write some code in IL assembler,
C++ or some other native language and call through that.

In Whidbey you'll be able to get a delegate wrapper for the function
pointer and call it that way.

You could try using Reflection.Emit to create a type to call that address at
runtime.
