Hi,

The only exception thrown directly by our code is FileLoadException. LoadFromStream calls BinaryFormatter and BinaryReader methods that could throw these exceptions according to their msdn topics -

EndOfStreamException The end of the stream is reached.
ObjectDisposedException The stream is closed.
IOException An I/O error occurs.

ArgumentNullException The serializationStream is null reference (Nothing in Visual Basic).
SerializationException The serializationStream supports seeking, but its length is 0.
SecurityException The caller does not have the required permission.

Hi David,

SaveToStream throws InvalidOperationException if your diagram contains instances of custom classes that are not registered for serialization using RegisterItemClass method. Called BinaryWriter and BinaryFormatter methods could throw following exceptions -

IOException An I/O error occurs.
ObjectDisposedException The stream is closed.

ArgumentNullException The serializationStream is null reference (Nothing in Visual Basic).

-or-

The graph is null.

SerializationException An error has occurred during serialization, such as if an object in the graph parameter is not marked as serializable.

SecurityException The caller does not have the required permission.
