一，上代码

using System;namespace FuncDemo{    class Program    {        static void Main(string[] args)        {            //无参数的fanc委托            var ss1 = FuncCommon.GetT
     
      (() => {               return "HelloWorld";            });            Console.WriteLine(ss1);            //带参数的fanc委托            var ss = FuncCommon.GetTn
      
       ((str,m) =>            {                var cc = str + DateTime.Now.AddDays(1).ToString();                return cc+ m;            });            Console.WriteLine(ss);            Console.ReadKey();        }    }}
      
     

 

二，类代码

using System;using System.Collections.Generic;using System.Text;namespace FuncDemo{    public static class FuncCommon    {        public static T GetT
     
      (Func
      
        func)        {            T t = default(T);            t = func.Invoke();            return t;        }        public static T GetTn
       
        (Func
        
          func)        {            T t = default(T);            t = func.Invoke("HelloWorld","\n"+DateTime.Now.ToString());            return t;        }    }}
        
       
      
     

三，结果
