A.5.2C#中对字符串(string)的常用处理

using System;namespace testString
{class Program{static void Main(string[] args){string url &＃61; "C://Program Files//CE Remote Tools//5.01//bin//aa.jpg";Console.WriteLine("长度&＃xff1a;{0}",url.Length);//从前往后查 a的索引下标Console.WriteLine("从前往后查,&＃39;a&＃39;它的索引小标&＃xff1a;{0}",url.IndexOf(&＃39;a&＃39;));Console.WriteLine("从后往前查,&＃39;a&＃39;它的索引小标&＃xff1a;{0}", url.LastIndexOf(&＃39;a&＃39;));string str1 &＃61; "yuanbo,xiaomei,chongfei";string[] list &＃61; str1.Split(&＃39;,&＃39;);foreach (string a in list){Console.WriteLine(a);}string str2 &＃61; "你是小狗。狗";Console.WriteLine("用Relpace处理的串&＃xff1a;{0}",str2.Replace("狗","X"));Console.WriteLine("Substring:{0}", str2.Substring(str2.IndexOf("狗")));Console.WriteLine("Substring:{0}",str2.Substring(0,3));Console.ReadLine();}}
