When overridden in a derived class, reconstructs a security object with a specified state from an XML encoding.
[Visual Basic] Public MustOverride Sub FromXml( _ ByVal elem As SecurityElement _ ) Implements ISecurityEncodable.FromXml [C#] public abstract void FromXml( SecurityElement elem ); [C++] public: virtual void FromXml( SecurityElement* elem ) = 0; [JScript] public abstract function FromXml( elem : SecurityElement );

| ArgumentException | The elem parameter does not contain the XML encoding for an instance of the same type as the current instance.

Remarks
Custom code that extends security objects needs to implement the ToXml and FromXml methods to make the objects security-encodable.
Notes to Inheritors: You must implement this method in a derived class.
