WebService 返回json格式和返回xml格式的数据

返回json格式

//using System.Web.Script.Services;
        [WebMethod]
        [ScriptMethod(UseHttpGet = true, ResponseFormat = ResponseFormat.Json)]
        public void HelloWorld()
        {
            Context.Response.Clear();
            Context.Response.ContentType = "application/json";
            Model.User.User_User user = new Model.User.User_User();
            user.UserName = "我们";
            user.UID = 1;
            user.UserPassWord = "123456";
            Jayrock.Json.JsonTextWriter writer = new Jayrock.Json.JsonTextWriter();
            Jayrock.Json.Conversion.JsonConvert.Export(user, writer);
            Context.Response.Write(writer.ToString());
        }

返回xml格式
