delegate object as an argument

[James]

Hello,

I tried to pass a delegate object to a function, it works fine if the
access modifier is private but gives me a compile error when the
access modifier of the function is public. Can anyone explain why ?
ex:
class
{
delegate int testdelegate(in t temp) ;
public void testfunction1(t estdelegate test, int temp) //gives
errror
{ }
private void testfunction2(t estdelegate test,int temp) //works fine
{ }
static void Main()
{ }
}

Thanks,
James.
