删除<字符串 xmlns= "http://tempuri.org/" >

Question

我已经谷歌搜索了很多，但我找不到任何解决方案：

  public class WebService : System.Web.Services.WebService {
        public WebService () {
            //Uncomment the following line if using designed components 
            //InitializeComponent(); 
        }
        [WebMethod]
        [ScriptMethod(ResponseFormat = ResponseFormat.Json)]
        public  string GetStudentInfo(int SerialNo)
        {
            Student obj = new Student();
            if (SerialNo is int)
            {
                int Serial = SerialNo;
                Student Stu;
                var da = new SqlDataAdapter("SELECT * from Courserecord where SNO='" + Serial + "'", con);
                var dt = new DataTable();
                da.Fill(dt);
                foreach (DataRow dr in dt.Rows)
                {
                    Stu = new Student
                              {
                                  SerialNo = Convert.ToInt32(dr["SNO"]),
                                  StudentName = dr["StudentName"].ToString(),
                                  Gender = dr["gender"].ToString(),
                                  CollegeName = dr["CollegeName"].ToString(),
                                  FathersName = dr["FatherName"].ToString(),
                                  MotherName = dr["MotherName"].ToString(),
                                  Address = dr["Address"].ToString(),
                                  City = dr["City"].ToString(),
                                  State = dr["State"].ToString(),
                                  ContactNo = dr["ContactNO"].ToString(),
                                  EmailId = dr["Emailid"].ToString(),
                                  //
                                  Course = dr["Course"].ToString(),
                                  DateFrom = dr["DateFrom"].ToString(),
                                  DateTo = dr["DateTo"].ToString(),
                                  Department = dr["Department"].ToString(),
                              };
                    return new JavaScriptSerializer().Serialize(Stu).ToString();
                }
            }

获得响应时，我将获得<string xmlns="http://tempuri.org/">标签。我们如何删除此内容，请帮助。

XmlDocument _doc = new XmlDocument();
_doc.LoadXml(_data);
return Request.CreateResponse(HttpStatusCode.OK, JObject.Parse(_doc.InnerText));
