链接两个字符串用“+”号

string s1 = "This is:"; string s2 = "ASP.NET"; Response.Write(s1+s2); Response.Write(20+30); Response.Write("10"+"20");

大小写转换

string s1 = "This is:"; string s2 = "ASP.NET"; Response.Write(s1+s2); Response.Write(20+30); Response.Write("10"+"20"); Response.Write(s1.ToUpper()); Response.Write(s2.ToLower());

除去前后空白。也可以使用TrimStart()或者使用TrimEnd（）

string bookname = " 去掉前后空格 "; Response.Write("["+bookname.Trim()+"]");

取出部分字符串

string length = "what's your name"; Response.Write(length.Substring(3)+" "); Response.Write(length.Substring(3,5));

判断摸个字出现的位置

取出扩展名：

string pageName = Request.FilePath; Response.Write(pageName + " ");

替换某个字符串和删除字符串中间的空白

string pageUrl = Request.Url.ToString(); Response.Write(pageUrl.Replace("aspx", "ascx") + " "); Response.Write(length.Replace(" ",""));//删除字符串中间的空白

将字符串拆成字符串数组

string EmpName = "Adams,Richard,Jerry,Sophie"; string[] EmpArray = EmpName.Split(new char[]{','});//以逗号为分界点 Response.Write("数组长度：" + EmpArray.Length.ToString() + " "); Response.Write(EmpArray[0].ToString() + " ");

将字符串数组组成一个字符串

string[] Aname = { "dffk", "sjfkdfj", "dfhdh", "fdjskfj" }; string Anames = string.Join(";",Aname); Response.Write(Anames + " ");//字符串彼此之间以“;”隔开
