关于JSON转换的问题

Question

请问能不能直接把DATASET转换为JSON呢?  public static string ToJSON(this object obj)  {  JavaScriptSerializer serializer = new JavaScriptSerializer();  return serializer.Serialize(obj);  }  public static string ToJSON(this object obj, int recursionDepth)  {  JavaScriptSerializer serializer = new JavaScriptSerializer();  serializer.RecursionLimit = recursionDepth;  return serializer.Serialize(obj);  }
