也可以不用设置地址

        }

 调用

 var client = WCFHandler.GetMapBusinessDataClient();
            //MapBusinessDataClient client = new MapBusinessDataClient();
            client.OpenAsync();
            client.QueryZQaccpCompleted += (s, e) =>
            {
                try
                {
                    if (e.Error == null && e.Result != null)
                    {
                        if (e.Result.Count == 0)
                        {
                         }
                   }
                }
                catch (Exception ex)
                {
                    MessageBox.Show(ex.ToString());
                }
            };
            client.QueryZQaccpAsync(View.BTime, View.ETime, View.type);
            client.CloseAsync();
