从WCF服务返回的JSON数据包含转义字符

我有一个工作的WCF – WPF应用程序工作，但我正在寻找一些优化。 下面是我的代码，其中WCF restful服务公开JSON数组，并且WPF UI正在接收它而没有任何问题。

WCF：

public clsStatus[] GetAllStatus() { DataTable dt = new DataTable(); List lstGetAllStatus = new List(); try { dt = // My Data Table foreach (DataRow dr in dt.Rows) { dcStatus objGetAllStatus = new clsStatus(); objGetAllStatus.Id = Convert.ToInt32(dr["Id"]); objGetAllStatus.Status = dr["Status"].ToString(); lstGetAllStatus.Add(objGetAllStatus); } } return lstGetAllStatus.ToArray(); } 

在WPF UI中：

 public ObservableCollection InvokeGet(string sUrl) { System.Net.WebRequest request = System.Net.HttpWebRequest.Create(sUrl); request.Method = "GET"; request.UseDefaultCredentials = true; request.ContentLength = 0; System.Net.HttpWebResponse response = request.GetResponse() as System.Net.HttpWebResponse; Stream objResponseStream = response.GetResponseStream(); StreamReader reader = new StreamReader(objResponseStream); string objResponseString = reader.ReadToEnd(); response.Close(); JavaScriptSerializer objJsonserialiser = new JavaScriptSerializer(); objJsonserialiser.MaxJsonLength = 999999999; T[] arrResult = objJsonserialiser.Deserialize(objResponseString); return new ObservableCollection(arrResult); } 

这种方式序列化/反序列化工作正常，而当我进行下面显示的更改时，反序列化不再有效：

在WCF中：

 public string[] GetAllStatus() { DataTable dt = new DataTable(); try { dt = // My Data Table string jsonresp = JsonConvert.SerializeObject(dt, Formatting.None); } return jsonresp; } 

在WPF中：

 public ObservableCollection InvokeGet(string sUrl ) { System.Net.WebRequest request = System.Net.HttpWebRequest.Create(sUrl); request.Method = "GET"; request.UseDefaultCredentials = true; request.ContentLength = 0; System.Net.HttpWebResponse response = request.GetResponse() as System.Net.HttpWebResponse; Stream objResponseStream = response.GetResponseStream(); StreamReader reader = new StreamReader(objResponseStream); string objResponseString = reader.ReadToEnd(); response.Close(); dsReportRequests dsrepreq = new dsReportRequests(); //This conversion is failing with error dsrepreq = JsonConvert.DeserializeObject(objResponseString); } 

错误： "Error converting value "[{"Id":11280,"statName}]" to type 'clsStat[]'. Path '', line 1, position 759." "Error converting value "[{"Id":11280,"statName}]" to type 'clsStat[]'. Path '', line 1, position 759."

我发现更改后的代码中的JSON格式包含转义字符（ ），这似乎在反序列化时导致错误。
