Error while reading data from cache

Question

Hi,
I am implementing IPofSerializer for an object of C#. I have successfully written C# object.
I have also read the first object.
But when I am going to read the second object's last field which of type boolean it is giving me error:
System.IO.EndOfStreamException was unhandled by user code
Message="Unable to read beyond the end of the stream."
Source="mscorlib"
