What is generic delegate

Question

What is generic delegate and how to use it.

Vulpes · Answer

A generic delegate is a delegate which takes one or more type parameters.
An example is the Func delegate which represents a method which takes a parameter of type T and returns a value of type TResult.
Here's a simple example of using this generic delegate:
using System;
class Test
{
static void Main()
{
Func func = CreateString;
string str = func(new char[]{'a', 'b', 'c'});
Console.WriteLine(str); // abc
Console.ReadKey();
}
static string CreateString(char[] chars)
{
return new string(chars);
}
}
