反序列化仅在我关闭客户端时完成

Question

我正在尝试通过 tcp stream 从客户端向服务器发送数据包。客户端连接到服务器并尝试发送图像。 但是，只有当我关闭客户端时，服务器才会获取图像。 （服务器在我关闭客户端的同一时刻获取图像）

我使用 ProtoBuf-Net 进行序列化和反序列化。 这是我的相关代码：

这是我的客户端代码：

// Connect to the client
client.Connect(Client.SERVER_IP, 1729);

// Capture screenshot
Bitmap captureBitmap = new Bitmap(Screen.PrimaryScreen.Bounds.Width, 
Screen.PrimaryScreen.Bounds.Height, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
System.Drawing.Rectangle captureRectangle = Screen.PrimaryScreen.Bounds;
Graphics captureGraphics = Graphics.FromImage(captureBitmap);
captureGraphics.CopyFromScreen(captureRectangle.Left, captureRectangle.Top, 0, 0, 
captureRectangle.Size);

// Serialize the screenshot to the socket's stream
ImageConverter img = new ImageConverter();
Packet<byte[]> packet = new Packet<byte[]> { value = (byte[])img.ConvertTo(captureBitmap, typeof(byte[])), type = PacketType.IMAGE });
Serializer.SerializeWithLengthPrefix(stream, packet.GetType().AssemblyQualifiedName, PrefixStyle.Base128);
Serializer.Serialize(stream, packet);

stream.Flush();

这是我的服务器代码：

ImageConverter imageConverter = new ImageConverter();
// Wait for client to conncet
var client = new ExtendedTcpClient(listener.AcceptTcpClient());
currentClientControlling = client;

// Deserialize type
var typeName = Serializer.DeserializeWithLengthPrefix<string>(stream, PrefixStyle.Base128);
var type = Type.GetType(typeName);

// Register the type
var model = RuntimeTypeModel.Default;
model.Add(type, true);

// Deserialize the data
var bytes = model.Deserialize(stream, null, type);

var image = (Bitmap)imageConverter.ConvertFrom(bytes);

这是我的数据包 model：

public enum PacketType
{
    IMAGE
}

[ProtoContract]
public class Packet<T>
{
    [ProtoMember(1)]
    public PacketType type { get; set; }

    [ProtoMember(2)]
    public T value { get; set; }
}

我没有弄清楚问题是什么。 但是，我通过替换Serializer.Serialize(stream, packet);解决了这个问题使用Serializer.SerializeWithLengthPrefix(stream, packet, PrefixStyle.Base128);
