Snippet of the code not working could help us see where the problem may be...

I can Serialize And Deserialize In One Application . i workinn Server And client Application so i need Send Struct to Client when i serialize Struct and Send , in client Application can't Deserialize Struct

[Mark Salsbery]

The problem is, the same assembly needs to be used to deserialize as the one that serialized it. There's ways around this though, if you don't want to keep a separate assembly to maintain on both ends. Please post the EXACT exception message (entirely) and I'll show you an example...If you'd like. You can get the message from the exception by wrapping your deserialize code in a try block and adding something like

...  
catch ( SerializationException^ e )
    {
        Console::WriteLine( "Failed to deserialize. Reason: {0}", e->Message );
        //throw;
    }

In order to serialize in one assembly and deserialize in another either you need to maintain same assembly in both applications or you use a technique described here: Advanced Binary Serialization: Deserializing an Object Into a Different Type Than the One It was Serialized Into[^] The example is in c# but you should be able to use the same principle in C++ .Net too. Hope it helps.
