string result = System.Web.HttpUtility.UrlDecode("%E6%9C%8D%E5%8A%A1%E5%99%A8%E7%AB%AF%E6%8F%90%E7%A4%BA%E4%BF%A1%E6%81%AF%EF%BC%9A%E8%B0%83%E7%94%A8%E8%80%85%E6%97%A0%E6%9D%83%E9%99%90%E8%B0%83%E7%94%A8%E6%AD%A4%E6%8E%A5%E5%8F%A3");
using System.Web;string ss = HttpUtility.UrlEncode(str);
string sa = HttpUtility.UrlDecode(str);
即可翻译
