C# Deserialization Over TCP
I have now an issue with deserializing an object sent over TCP.
When deserializing, I get the following SerializationException (code below):
Additional information: Binary stream '0' does not contain a valid BinaryHeader. Possible causes are invalid stream or object version change between serialization and deserialization.
Serialization code:
public static void SerializeRO(Stream stream, ReplicableObject ro) {
MemoryStream serializedObjectStream = new MemoryStream();
Formatter.Serialize(serializedObjectStream, ro);
BinaryWriter bw = new BinaryWriter(stream);
bw.Write(serializedObjectStream.Length);
serializedObjectStream.WriteTo(stream);
serializedObjectStream.Close();
bw.Close();
}
Deserialization code:
public static List<ReplicableObject> ParseStreamForObjects(Stream stream) {
List<ReplicableObject> result = new List<ReplicableObject>();
while (true) {
if (!(stream as NetworkStream).DataAvailable) break;
BinaryReader br = new BinaryReader(stream);
int length = br.ReadInt32();
byte[] bytes = br.ReadBytes(length);
MemoryStream ms = new MemoryStream(bytes);
ms.Position = 0;
开发者_运维知识库 // ERROR OCCURS ON THE LINE BELOW
result.Add((ReplicableObject) Formatter.Deserialize(ms));
ms.Close();
br.Close();
}
return result;
}
The objects are being serialized at runtime, so I don't think it's a versioning issue. I am new to streaming etc, so I may have missed something obvious.
I'd like to suggest what I think it could be, but I'm really stuck. :)
Thanks.
serializedObjectStream.Length
is a long
.
You're writing a 64-bit value to the network, but you're trying to read it as a 32-bit int
.
