Assembly: mscorlib (in mscorlib.dll)

public override SecurityElement ToXml ()
public SecurityElement ToXml ()
public override function ToXml () : SecurityElement
Not applicable.

Return Value

An XML encoding of the permission, including state information.

The following code example shows how the ToXml method performs if you execute the method from your code. For the complete code example, see the FileDialogPermission class.

NoteNote:

The code example is intended to show the behavior of the method, not to demonstrate its use. In general, the methods of permission classes are used by the security infrastructure; they are not typically used in applications.

private bool ToFromXmlDemo()
{

    bool returnValue = true;

    fileDialogPerm2 = new FileDialogPermission(PermissionState.None);
    fileDialogPerm2.FromXml(fileDialogPerm1.ToXml());
    Console.WriteLine("Result of ToFromXml = " +
        fileDialogPerm2.ToString());

    return returnValue;
}

// ToXml creates an XML encoding of the permission and its current 
// state; FromXml reconstructs a
// permission with the specified state from the XML encoding.

{
    boolean returnValue = true;

    FileDialogPermission fileDialogIdPerm2[] = 
        new FileDialogPermission[1];
    FileDialogGenerator fileDialogGen1 =  
        new FileDialogGenerator();
    FileDialogGenerator fileDialogGen2 =  
        new FileDialogGenerator();
    fileDialogGen1.ResetIndex();
    while(fileDialogGen1.CreateFileDialog(fileDialogIdPerm1, 
        fileDialog1)) {
        if (fileDialogIdPerm1[0] == null) {
            continue ;
        }

            fileDialogIdPerm2[0].FromXml(fileDialogIdPerm1[0].ToXml());
            Console.WriteLine(("Result of ToFromXml = " 
                + fileDialogIdPerm2[0].ToString()));
        }
