Hi,

I converted vb6 code to C# and getting this error.

C#

public void test()
{
	//code...
}
public void CallTest(int i)
{
	//after some operation 
	return i;
}

form_Load()
{
	CallTest(AddressOf test); // Getting error.
}

Giving error 'AddressOf' expression cannot be converted to 'Integer' because 'Integer' is not a delegate type.

I want get the address (memory pointer) of to the function "DirPickupSearchProcessReply" in vb.net or C# Please suggest how can i get?

You need to define a delegate type with the same signature of the method. (in this case a very simple one)

public delegate void TestDelegate();

You need to use this type as parameter type:

public void CallTest(TestDelegate i) {
  i();
}

... calling it with the test method as delegate
CallTest(new TestDelegate(test));

This is because it is unsafe to assume a method address is simply an integer and would make static type checking (to see if the method fits the expectations) nearly impossible. What would happen if you would pass i + 1?
