Question

我正在尝试从.asmx web服务填充我的jquery数据表，但是抛出内部服务器500错误。

为什么？

 [WebMethod(EnableSession = true)]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json, UseHttpGet=true)]
        //[ScriptMethod(UseHttpGet = true)]
        public string getUsers()
        {
            try
            {
                basicoperation bop = new basicoperation();
               // Context.Response.Output.Write(bop.getUsers());
                DataTable dt;

                dt= bop.getUsers();

                dt.TableName = "usersDT";

                string json = JsonConvert.SerializeObject(dt);

                return json;
            }
            catch (Exception ex)
            {

                throw ex;
            }


        }

此网络服务返回

此XML文件似乎没有与之关联的任何样式信息。文档树如下所示。

<string xmlns="http://tempuri.org/">
[{"ID":1,"UserName":"Yasir","Password":"123"},{"ID":2,"UserName":"asd","Password":"asdasd"},{"ID":3,"UserName":"Tester","Password":"123"},{"ID":4,"UserName":"rqads","Password":"12"},{"ID":5,"UserName":"asd","Password":"asda"},{"ID":6,"UserName":"asd","Password":"asda"},{"ID":7,"UserName":"hunain","Password":"123"},{"ID":8,"UserName":"hunain","Password":"123"},{"ID":9,"UserName":"username","Password":"123"},{"ID":10,"UserName":"","Password":""},{"ID":11,"UserName":"da","Password":"asd"},{"ID":12,"UserName":"sdas","Password":"asdas"},{"ID":13,"UserName":"","Password":""},{"ID":14,"UserName":"fdsf","Password":"sf"},{"ID":15,"UserName":"","Password":""},{"ID":16,"UserName":"","Password":""},{"ID":17,"UserName":"","Password":""}]
</string>

但是，它仍无效。

这是我的js代码：

我在点击按钮时调用show（）函数。我花了整整一天时间，它仍然没有用。在这方面，将非常感谢帮助。

为什么我的jquery数据表没有填满？
