Hello all,
I am trying to serialize a class that I have created, it works fine =
until I instanciate the class via a new Application Domain's =
CreateInstanceFrom method. When I attempt to serialize I keep getting =
this exception....


An unhandled exception of type =
'System.Runtime.Serialization.SerializationException' occurred in =
mscorlib.dll

Additional information: The type =
System.Runtime.Serialization.SerializationInfo in Assembly mscorlib, =
Version=3D1.0.3300.0, Culture=3Dneutral, =
PublicKeyToken=3Db77a5c561934e089 is not marked as serializable.

Can anyone help ?

Many thanks (in advanced)

Hello Alan,

For a class to be serializable, all its public members and properties should
be of serializable types.
Your class probably violates this restriction by exposing a property or a
member of type SerializationInfo (hmm, what for?).

Anyway, if you could post some code snippet, you would really facilitate
tracking down the root of the problem.
