C# 三种泛型委托的使用Demo

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Demo
{
    class Program
    {

        static void Main(string[] args)
        {
            Action<string> test = delegate(string s) { Console.WriteLine(s); };
            test("Action delegate Test");

            Predicate<string> predicateTest = delegate(string s) { return s == "Hello"; };
            Console.WriteLine(predicateTest("Hello"));

            Func<string, string> func = delegate(string s) { return s + " Func"; };
            string result = func("Hello");
            Console.WriteLine(result);

            Console.ReadKey();
        }
    }
}

作为个人温习，请勿喷！
