新建一泛型委托类GenericDelegate.cs ,在里面进行委托的定义

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

namespace CSharpAdvancedDelegate
{
    delegate void GenericDelegate1<T>(T t);
    public class GenericDelegate
    {
        public static void InvokeDelegate()
        {
            GenericDelegate1<string> genericDelegate = new GenericDelegate1<string>(Method1);
            GenericDelegate1<int> genericDelegate2 = new GenericDelegate1<int>(Method2);
            genericDelegate("我是泛型委托1");
            genericDelegate2(23);
        }
        /// <summary>
        /// 泛型委托方法1
        /// </summary>
        /// <param name="str"></param>
        public static void Method1(string str)
        {
            Console.WriteLine(str) ;
        }
        /// <summary>
        /// 泛型委托方法2
        /// </summary>
        /// <param name="str"></param>
        public static void Method2(int str)
        {
            Console.WriteLine(str);
        }
    }
}

在Program.cs类中的Main函数中添加以下代码

static void Main(string[] args)
{
      Console.WriteLine("=================泛型委托=================");
      GenericDelegate.InvokeDelegate();
      Console.Read();
}

系统自带的委托的应用

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

namespace CSharpAdvancedDelegate
{  
    public class GenericDelegate
    {
        public static void InvokeDelegate()
        {
            //系统自带的无返回值委托
            Action<string> action = new Action<string>(Method1); //填写的是方法名
            action("我是泛型委托1");  //填写的是方法中的参数

            //一个是参数一个是返回值
            Func<string, string> func = new Func<string, string>(Method3); 
            Console.WriteLine(func("有返回值有参数的泛型委托"));          
        }
        /// <summary>
        /// 泛型委托方法1
        /// </summary>
        /// <param name="str"></param>
        public static void Method1(string str)
        {
            Console.WriteLine(str) ;
        }
        /// <summary>
        /// 泛型委托方法2
        /// </summary>
        /// <param name="str"></param>
        public static void Method2(int str)
        {
            Console.WriteLine(str);
        }
        /// <summary>
        /// 有返回值有参数的泛型委托方法3
        /// </summary>
        /// <param name="str"></param>
        /// <returns></returns>
        public static string  Method3(string str)
        {
            return str;
        }
    }
}

在Main()函数中的调用

static void Main(string[] args)
{
      Console.WriteLine("=================泛型委托=================");
      GenericDelegate.InvokeDelegate();
      Console.Read();
}
