GOTO的用法如下

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

namespace GotoDemo
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Console.WriteLine("请输入需要查找的文字：");
            string inputstr = Console.ReadLine(); string[] mystr = new string[5];
            mystr[0] = "zifubao";
            mystr[1] = "weixin";
            mystr[2] = "QQ";
            mystr[3] = "yinlian";
            mystr[4] = "jingdong";
            for (int i = 0; i < mystr.Length; i++)
            {
                if (mystr[i].Equals(inputstr))
                {
                    goto Found;
                }
            }
            Console.WriteLine("您查找的{0}不存在！", inputstr);
            goto Finish;

        Found:
            Console.WriteLine("您查找的{0}存在！", inputstr);
        Finish:
            Console.WriteLine("查找完毕");
            Console.ReadLine();

        }
    }
}
