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=1.0.3300.0, Culture=neutral, PublicKeyToken·7a5c561934e089 is not marked as serializable.

Can anyone help ?

Many thanks (in advanced)

try putting [Serializable] before your class in c#...I
don't know the syntax in vb.net. example
c#
[Serializable]
class MyClass
{
MyClass()
{
}
public void OtherMethod()
{
{
private string y = null;
private string x = null;
}

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.
