CodeAccessPermission.FromXml Method
.NET Framework 3.0
When overridden in a derived class, reconstructs a security object with a specified state from an XML encoding.
Namespace: System.Security
Assembly: mscorlib (in mscorlib.dll)
Assembly: mscorlib (in mscorlib.dll)
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 override this method in a derived class.The following code example shows an override of the FromXml method. This code example is part of a larger example provided for the CodeAccessPermission class.
public: virtual void FromXml( SecurityElement^ e ) override { // 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. String^ elUnrestricted = e->Attribute("Unrestricted"); if ( nullptr != elUnrestricted ) { m_Unrestricted = Boolean::Parse( elUnrestricted ); return; } String^ elName = e->Attribute("Name"); m_Name = elName == nullptr ? nullptr : elName; }
