这是一个http请求，她能向手机发送一个短信，因为短信中的内容包含有中文，导致手机看到的是乱码，现在服务器端该做何处理。其中我发现HttpUtility.UrlEncode，HttpUtility.UrlDecode，Server.UrlEncode，Server.UrlDecode在控制台应用程序都不能用。问题是能用该怎么用，不能用该采取什么办法

Answer 1

添加System.Web的引用，调用HttpUtility.UrlEncode来编码。然后发送，还有要注意和网站编码保持一致！[align=center]*****************************************

Answer 2

//发送的时候
            var body = "我是中文的";
            var base64 = Convert.ToBase64String(Encoding.UTF8.GetBytes(body));
 string url = "http://http.sms0551.com/tx/?uid=82612&pwd=123456&mobile=" + phone + "&content=" +  base64 ;//body中包含中文
string result = ObtainHtml2(url);
//接收的时候private static string ObtainHtml2(string url)
        {
            string strHtml;
            try
            {
                WebClient wc = new WebClient();
                Byte[] bHtml = wc.DownloadData(url);                strHtml = System.Text.Encoding.UTF8.GetString(bHtml);
var body2 = Encoding.UTF8.GetString(Convert.FromBase64String(strHtml));
            }            catch
            {
                strHtml = "";
            }
            return strHtml;
        }

回复一楼：控制台应用程序，System.Web下没有HttpUtility类
回复二楼：我把strHtml = System.Text.Encoding.UTF8.GetString(bHtml)改成gb2312的编码也不行
回复三楼：没成功，倒是把中文转成ASCII码了

Answer 4

这句话在作怪System.Text.Encoding.UTF8.GetString(bHtml);

Answer 5

回复一楼：控制台应用程序，System.Web下没有HttpUtility类就是用 HttpUtility.UrlEncode 和 UrlDecode 啊
控制台程序需要添加 System.Web.dll
