C# Func and Action types

The Func type provides a way to store anonymous methods. For the Func type, the first type parameters are the arguments to the methods, and the final type parameter is the return value.


using System;
using System.Collections.Generic;
using System.IO;
using System.Text;
using System.Xml.Serialization;
using Microsoft.VisualStudio.TestTools.UnitTesting;
public class UnitTest1
    public void FuncTypeTest()
        Func<string, bool> validator =
        word =>
            var count = word.Length;
            return count > 4;
        var isValid = validator("AjitGoel");

Action type objects do not return a value. They are similar to a void method.
A Func type on the other hand returns a result.

Action<int> action1 = (int counter) => Console.WriteLine("Write {0}", counter);
