必须使用适当的属性或方法修改此标头.

在线: request.Headers.Add("Content-Type", "text/x-gwt-rpc; charset=utf-8");

            byte[] byteArray = Encoding.UTF8.GetBytes(postData);
            request.ContentLength = byteArray.Length;
            Stream dataStream = request.GetRequestStream();
            dataStream.Write(byteArray, 0, byteArray.Length);
            dataStream.Close();

使用WebRequest.ContentType属性.某些标头只能使用API​​属性进行设置.

编辑:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.androidlost.com/androidlost/greet");
request.ContentType = "text/x-gwt-rpc; charset=utf-8";
