delegate and multithreading

Question

what is the difference between multithreading and delegate in C#?

Vulpes · Answer

A delegate can represent any method which has the same signature (i.e. type and number of arguments) and the same return type as the delegate does. So if you have: delegate int MyDelegate(int i); class Test { public int Square(int i) { return i * i; } } you can assign the method to the delegate and call it via the delegate like this: Test t = new Test(); MyDelegate d = t.Square; int result = d(9); // 81 Multi-threading simply means that there are multiple threads of execution running simultaneously within a particular process. If you only have a single processor this is an illusion - the operating system allocates a 'time slice' to each thread in such a way as to make it appear to the user that the threads are running simultaneously when in fact they're sharing processor time.
