//对字符进行UrlEncode编码 string text= System.Web.HttpUtility.UrlEncode("heart", System.Text.Encoding.UTF8); //对字符进行UrlDecode解码 string data = System.Web.HttpUtility.UrlDecode(text, System.Text.Encoding.UTF8);
在c#中,HttpUtility.UrlEncode("www+mzwu+com")编码结果为www%2bmzwu%2bcom，在和Java开发的平台做对接的时候，对方用用url编码后再对其进行MD5加密，url编码之后的字符串为大(www%2Bmzwu%2Bcom)写这样加密出来的字符串就.net平台的不匹配，
以下供上方法就是解决HttpUtility.UrlEncode编码由小写转化为大写字母
/// <summary> /// 对字符进行UrlEncode编码 /// string转Encoding格式 /// </summary> /// <param name="text"></param> /// <param name="encod">编码格式</param> /// <param name="cap">是否输出大写字母</param> /// <returns></returns> public static string UrlEncode(string text, Encoding encod, bool cap = true) { if(cap) { StringBuilder builder = new StringBuilder(); foreach (char c in text) { if (System.Web.HttpUtility.UrlEncode(c.ToString(), encod).Length > 1) { builder.Append(System.Web.HttpUtility.UrlEncode(c.ToString(), encod).ToUpper()); } else { builder.Append(c); } } return builder.ToString(); } else { string encodString = System.Web.HttpUtility.UrlEncode(text, encod); return encodString; } } /// <summary> /// 对字符进行UrlDecode解码 /// Encoding转string格式 /// </summary> /// <param name="encodString"></param> /// <param name="encod">编码格式</param> /// <returns></returns> public static string UrlDecode(string encodString, Encoding encod) { string text = System.Web.HttpUtility.UrlDecode(encodString, encod); return text; }
