1.百度编码、解码
你在百度中输入"彭成刚",点击搜索后URL栏中会变成"%C5%ED%B3%C9%B8%D5",这是怎么编码的,如何解码.下面两段代码能解决这两个疑问:
//百度编码
Console.WriteLine(System.Web.HttpUtility.UrlEncode("彭成刚", System.Text.UnicodeEncoding.GetEncoding("GB2312")).ToUpper());
//百度解码
Console.WriteLine(System.Web.HttpUtility.UrlDecode("%C5%ED%B3%C9%B8%D5", System.Text.UnicodeEncoding.GetEncoding("GB2312")));
2.HTML编码、解码函数
//HTML编码
System.Web.HttpUtility.HtmlEncode(string); Server.HtmlEncode(string)
//HTML解码
System.Web.HttpUtility.HtmlDecode(string); Server.HtmlDecode(string)
即对HTML标签编码解码,非HTML标签不对其解码 比如
--->
3.URL中编码、解码
//URL编码
System.Web.HttpUtility.UrlEncode(string); Server.UrlEncode(string);
System.Web.HttpUtility.UrlPathEncode(string); Server.UrlPathEncode(string);
UrlEncode与UrlPathEncode编码获范不一样
比如: UrlEncode对整个URL进行编码(即http://www.zzcn.net/全部编码)
UrlPathEncode对http://之后的内容进行编码(即www.zzcn.net)
//URL解码
System.Web.HttpUtility.UrlDecode(string); Server.UrlDecode(string);
4.UTF-8,GB2312转换
utf-8>>gb2312
string content = "彭成刚";
byte[] conby = Encoding.UTF8.GetBytes(content);
content = Encoding.GetEncoding("gb2312").GetString(conby);
Console.WriteLine(content);
反之就不写啦,希望对大家有进一步认识,不足的请指正补充,谢谢
