When overridden in a derived class, reconstructs a security object with a specified state from an XML encoding.
Assembly: mscorlib (in mscorlib.dll)
Custom code that extends security objects needs to implement the ToXml and methods to make the objects security-encodable.Notes to Inheritors
You must override this method in a derived class.
The following code example shows an override of the method. This code example is part of a larger example provided for the CodeAccessPermission class.
Public Overrides Sub FromXml(ByVal e As SecurityElement) ' The following code for unrestricted permission is only included as an example for ' permissions that allow the unrestricted state. It is of no value for this permission. Dim elUnrestricted As String = e.Attribute("Unrestricted") If Nothing <> elUnrestricted Then m_Unrestricted = Boolean.Parse(elUnrestricted) Return End If Dim elName As String = e.Attribute("Name") m_name = IIf(elName Is Nothing, Nothing, elName) End Sub 'FromXml
