Server.UrlEncode()指定GBK编码

问题：Server.UrlEncode(“你好”) 无法指定编码格式

解决方法：
方法一、调用Server.UrlEncode()之前加入
Response.ContentEncoding = System.Text.Encoding.GetEncoding(“GBK”)
方法二、在web.config中配置：

<configuration> <system.web>  <globalization requestEncoding="GBK" responseEncoding="GBK" /> </system.web></configuration>

原因：

查看Server.UrlEncode()源码 (HttpServerUtility类)：

public string UrlEncode(string s) {    Encoding e = (_context != null) ? _context.Response.ContentEncoding : Encoding.UTF8;    return HttpUtility.UrlEncode(s, e);}

而_context.Response.ContentEncoding的源码为

public Encoding ContentEncoding {    get {        if (_encoding == null) {        // use LKG config because Response.ContentEncoding is need to display [config] error            GlobalizationSection globConfig = RuntimeConfig.GetLKGConfig(_context).Globalization;            if (globConfig != null)                _encoding = globConfig.ResponseEncoding;            if (_encoding == null)                _encoding = Encoding.Default;        }        return _encoding;    }    set {        if (value == null)            throw new ArgumentNullException("value");        if (_encoding == null || !_encoding.Equals(value)) {            _encoding = value;            _encoder = null;   // flush cached encoder            if (_httpWriter != null)                _httpWriter.UpdateResponseEncoding();        }    }}
