Question

我正在连接到IIS 7休息Web服务器并发送gps读数。我们每20秒保存一次读数，但每60秒将其提交给Web服务。

这是我的联系：

    var readings = Reading.GetUnProcessReadings().ToList();

    var gpsreadings = new List<TruckGpsReading>();

    history.History = "TruckGpsReading count: " + readings.Count();

    var count = 1;
    while (readings.Any())
    {
      {
        gpsreadings = new List<TruckGpsReading>();
        if (readings.Any())
        {
          history.History = "No. Transactions to process: " + count;
          foreach (var reading in readings)
          {
            history.History = "Currently reading #" + count;
            history.History = "Processing reading: " + reading.DateTimeOfReading;
            Logging.Log("Starting ProcessGpsFile.ProcessReading 3", "ProcessReading", Apps.RemoteTruckService);
            var gpsreading = new TruckGpsReading();
            gpsreading.DateTimeOfReading = reading.DateTimeOfReading;
            gpsreading.Direction = reading.Direction;
            gpsreading.DriverNumber = CurrentIniSettings.DriverNumber;
            gpsreading.GpsReadingId = reading.ReadingId;
            gpsreading.Latitude = (float) reading.Latitude;
            gpsreading.Longitude = (float) reading.Longitude;
            gpsreading.Speed = reading.Speed;                
            gpsreading.TruckNumber = string.IsNullOrWhiteSpace(CurrentIniSettings.TruckNumber) ? "99" : CurrentIniSettings.TruckNumber;
            gpsreadings.Add(gpsreading);
            TotalReadings++;
            count++;
          }

          var response = client.SaveGpsReadings(globalSetting.TokenId, globalSetting.SourceId, gpsreadings.ToArray());
          if (response != "true")
          {
            history.History = "Transactions NOT saved: " + response;
            Logging.Log("ProcessGpsFile.ProcessReading: " + response, "ProcessReading", Apps.RemoteTruckService);
          }
          else
          {
            history.History = "Transactions saved.";
            Logging.Log("ProcessGpsFile.ProcessReading: Reading.DeleteGpsReadings(readings)", "ProcessReading",
                        Apps.RemoteTruckService);
            Reading.DeleteGpsReadings(readings);
          }
        }

这就是TruckGpsReading：

  [DataContract]
  public class TruckGpsReading
  {
    [DataMember]
    public string DriverNumber { get; set; }

    [DataMember]
    public string TruckNumber { get; set; }

    [DataMember]
    public float Latitude { get; set; }

    [DataMember]
    public float Longitude { get; set; }

    [DataMember]
    public DateTime DateTimeOfReading { get; set; }

    [DataMember]
    public int Speed { get; set; }

    [DataMember]
    public string Direction { get; set; }

    [DataMember]
    public int OdometerReading { get; set; }

    [DataMember]
    public Guid GpsReadingId { get; set; } 

  }

我发现每条记录发送的信息量大约为256字节，但似乎连接位于30k区域。我不确定是什么导致这种情况，或者是否有更好的解决方法。

我的问题是，当数据被发送时，它正在通过蜂窝网络传输。这些网络受月度数据使用的限制，我正在努力减少这种使用。

如果我在应用程序打开并保持连接时连接该服务，这是一个坏主意吗？我想我们可以在应用程序启动时连接并且每次我们发送时都有1次连接成本而不是连接。编辑我想补充一点，这个程序每天运行大约8到10个小时。

此外，有没有办法降低连接成本或找出连接后的操作？

我知道这是很多问题，但我是网络服务的新手。
