原有字符串http://www.baidu.com

要求：

1追加“一个神奇的网站”

2利用插入进行换行

3再移除换行

4替换“神奇”为“强大”

using System;using System.Collections.Generic;using System.Linq;using System.Text;//引用命名空间using System.Threading.Tasks;namespace ConsoleApplication4{    class Program    {        static void Main(string[] args)        {            StringBuilder mystringBuilder = new StringBuilder("http://www.baidu.com");            Console.WriteLine("==============Append================");            //追加对应的字符串            Console.WriteLine(mystringBuilder.Append("是一个神奇的网站"));            Console.WriteLine("==============Insert================");            //在对应位置插入指定的字符串            Console.WriteLine(mystringBuilder.Insert(20,"\n"));            Console.WriteLine("==============Remove================");            //移除从索引开始的N个字符            Console.WriteLine(mystringBuilder.Remove(20,1));            Console.WriteLine("==============Replace===============");            Console.WriteLine(mystringBuilder.Replace("神奇","强大"));            Console.WriteLine("==============AppendFormat==========");            int saveMoney = 2000;            Console.WriteLine(mystringBuilder.AppendFormat("并且为我省了{0:C}",saveMoney));            Console.ReadKey();        }    }}
