　　　　　　　　　　　　　　new System.Runtime.Serialization.Json.DataContractJsonSerializer(typeof(T));
                json.WriteObject(ms, t);
                strJson = json.ReadObject(ms).ToString();
            }

System.Web.Script.Serialization
例:

System.Web.Script.Serialization.JavaScriptSerializer jss =
                new System.Web.Script.Serialization.JavaScriptSerializer();
            strJson = jss.Serialize(t);
