StringBuilder 它就是拼接字符串的一个工具，拼成完成后，还是需要将它转回字符串。

using System;using System.Collections.Generic;using System.Diagnostics;using System.Linq;using System.Text;namespace _02StringBuilder{    class Program    {        static void Main(string[] args)        {            //string str = string.Empty;            //StringBuilder sb = new StringBuilder();            ////00:00:00.1022297            //Stopwatch sp = new Stopwatch();            //sp.Start();            //for (int i = 0; i < 100000; i++)            //{            //    //str += i;            //    sb.Append(i);            //}            //sp.Stop();            //Console.WriteLine(sp.Elapsed);            //Console.WriteLine(sb.ToString());            StringBuilder sb = new StringBuilder();            sb.Append("张三");            sb.Append("李四");            sb.Append("王狗蛋儿");            sb.Insert(1, "新来哒");            sb.Replace("王狗蛋儿", "***");            Console.WriteLine(sb.ToString());            Console.ReadKey();        }    }}
