CodeAccessPermission.ToXml Method

When overridden in a derived class, creates an XML encoding of the security object and its current state.

Namespace:  System.Security
Assembly:  mscorlib (in mscorlib.dll)

public abstract SecurityElement ToXml()

Return Value

Type: System.Security.SecurityElement
An XML encoding of the security object, including any state information.

Implements

ISecurityEncodable.ToXml()

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 ToXml method. This code example is part of a larger example provided for the CodeAccessPermission class.


public override SecurityElement ToXml()
{
    // Use the SecurityElement class to encode the permission to XML.
    SecurityElement esd = new SecurityElement("IPermission");
    String name = typeof( NameIdPermission).AssemblyQualifiedName;
    esd.AddAttribute("class", name);
    esd.AddAttribute("version", "1.0");

    // 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.
    if (m_Unrestricted)
    {
        esd.AddAttribute("Unrestricted", true.ToString());
    }
    if (m_Name != null) esd.AddAttribute( "Name", m_Name );
    return esd;
}
