“源数据中的无效字段:0”错误与ProtoBuf-Net和紧凑框架

在使用

ProtoBuf-Net在紧凑框架和完整的.Net框架之间进行序列化/反序列化时，有没有人知道任何问题？ 我有一个名为 LogData 的类，我在紧凑框架 3.5 下对其进行序列化，传输到服务器（运行 .Net Framework 4.0），然后对其进行反序列化。 有时它有效，有时它会抛出上述错误，我还没有将其缩小到任何特定原因。 我已经用不同的值做了很多测试，似乎找不到任何押韵或错误发生的原因。 我在下面包括我的类（减去各种构造函数）。 我已经多次查看了两端的字节缓冲区，但尚未发现通过线路从一侧发送到另一侧的数据存在差异。

[ProtoContract]
public class LogData
{
  [ProtoContract]
  public enum LogSeverity
  {
     [ProtoEnum(Name = "Information", Value = 0)]
     Information,
     [ProtoEnum(Name = "Warning", Value = 1)]
     Warning,
     [ProtoEnum(Name = "Error", Value = 2)]
     Error,
     [ProtoEnum(Name = "Critical", Value = 3)]
     Critical
  }
  [ProtoMember(1)]
  public string UserID { get; set; }
  [ProtoMember(2)]
  public string ComputerName { get; set; }
  [ProtoMember(3)]
  public ExceptionProxy Exception { get; set; }
  [ProtoMember(4)]
  public LogData.LogSeverity Severity { get; set; }
  [ProtoMember(5)]
  public string Source { get; set; }
  [ProtoMember(6)]
  public string Caption { get; set; }
  [ProtoMember(7)]
  public string Description { get; set; }
  [ProtoMember(8)]
  public DateTime TimeOfOccurrence { get; set; }
  [ProtoMember(9)]
  public Guid SessionID { get; set; }
  [ProtoMember(10)]
  public string MethodName { get; set; }
  [ProtoMember(11)]
  public string OSVersion { get; set; }
  [ProtoMember(12)]
  public string Category { get; set; }
  [ProtoMember(13)]
  public string Location { get; set; }
}
[ProtoContract]
public class ExceptionProxy
{
  [ProtoMember(1)]
  public Type ExceptionType { get; set; }
  [ProtoMember(2)]
  public string Message { get; set; }
  [ProtoMember(3)]
  public string StackTrace { get; set; }
  [ProtoMember(4)]
  public ExceptionProxy InnerException { get; set; }
}

这是我进行序列化和发送的代码

  private void WriteLogDataToServer(LogData data)
  {
     using (var client = new TcpClient())
     {
        client.Connect(Host, SignalLineServerPort);
        using (var stream = client.GetStream())
        {
           using (var ms = new MemoryStream())
           {
              Serializer.Serialize<LogData>(ms, data);
              var buffer = ms.GetBuffer();
              int position = 0;
              WriteFrameMarkers(stream);
              byte[] frameLengthBuffer = BitConverter.GetBytes(buffer.Length);
              stream.Write(frameLengthBuffer, 0, IntByteSize);
              while (position < buffer.Length)
              {
                 int length = Math.Min(ChunkSize, buffer.Length - position);
                 stream.Write(buffer, position, length);
                 position += ChunkSize;
              }
           }
        }
        client.Close();
     }         
  }

这是读取服务器上数据的代码

  public override LogData ReadData(NetworkStream stream)
  {
     if (stream.DataAvailable)
     {
        try
        {
           const int chunkSize = 250;
           byte[] buffer = new byte[IntByteSize];
           int messageSize = 0;
           int totalBytesRead = 0;
           LogData data;
           using (var ms = new MemoryStream())
           {
              if (!ReadFrameMarkers(stream))
                 return null;
              totalBytesRead = stream.Read(buffer, 0, IntByteSize);
              if (totalBytesRead != IntByteSize)
                 return null;
              messageSize = BitConverter.ToInt32(buffer, 0);
              totalBytesRead = 0;
              while ((totalBytesRead < messageSize))
              {
                 int bufferSize = Math.Min(chunkSize, messageSize - totalBytesRead);
                 buffer = new byte[bufferSize];
                 int bytesRead = stream.Read(buffer, 0, bufferSize);
                 if (bytesRead != 0)
                 {
                    totalBytesRead += bytesRead;
                    ms.Write(buffer, 0, bytesRead);
                 }
              }
              ms.Seek(0, SeekOrigin.Begin);
              data = Serializer.Deserialize<LogData>(ms);
           }
           return data;
        }
        catch (Exception ex)
        {
           Console.WriteLine(string.Format("Error occurred: {0}", ex.Message));
           return null;
        }
     }
     return null;
  }

var buffer = ms.GetBuffer();

byte[] msg = new byte[4096];
int bytesRead = someStreamClass.Read(msg, 0, 4096);
using (MemoryStream ms = new MemoryStream(msg, 0, bytesRead))
{    
    logData = Serializer.Deserialize<LogData>(ms);
}
