How to Correctly Deserialize a Struct Received Over TCP in C# and Avoid SafeArrayTypeMismatchException?

Deserializing Struct Received Over TCP in C#

Problem:

When sending a serialized struct, RemuseNetworkPacket, over TCP, deserialization on a separate machine results in a SafeArrayTypeMismatchException. The length prefix format is l=xxxx;;, where xxxx represents the packet length.

Solution:

The issue arises from the length prefix being handled as a string instead of an integer. Length-prefixing should be implemented correctly:

1. Convert packet length to bytes: Convert the length of the packet data (not including length prefix and header) into a byte array. This will typically result in 4 bytes.
2. Add length prefix and header: Concatenate the length byte array with the packet data header and the actual packet data.
3. Packet structure: The resulting packet structure should be: [Length (4 bytes)][Header (1 byte)][Data (x byte(s))].

Receiving and Deserializing:

1. Read length: Read the first 4 bytes (length) and convert them to an integer.
2. Read header: Read the next byte (header).
3. Read data: Read x bytes (where x is the length obtained in step 1) into a byte array.
4. Deserialize packet: Use the header from step 2 to determine the appropriate deserialization method and apply it to the byte array from step 3.
