Correct deserialization with BinaryFormatter

[Chesnokov Yuriy]

How to check Stream contains valid BinaryHeader to avoid deserialization exceptions such as Binary stream '0' does not contain a valid BinaryHeader?

Could you post some code ??? so we can see what your trying to do. ?

With great code, comes great complexity, so keep it simple stupid...:-\ :-\

I do not want that deserialization call formatter.Deserialize(ms); will result in Exception. Thus I need to check that MemoryStream ms; contains valid header which is used internally in BinaryFormatter.Deserialize() call.

It is very simple, MemoryStream contains your data for deserialization. With MemoryStream.GetBuffer(); you may get access to underlying byte[] array. It needs to check that in that array first bytes are valid BinaryHeader structure used inernally by BinaryFormatter during deserialization call. If there is garbage in the MemoryStream then BinaryFormatter will throw exception. I need to avoid that exception and make sure correct data will be passed for deserialization. Finally I found that link that resolves the issue http://primates.ximian.com/~lluis/dist/binary_serialization_format.htm[^]
