示例1: Union
' Return a new object that contains the union of 'this' and 'target'.
' Note: You do not have to implement this method. If you do not, the version
' in CodeAccessPermission does this:
' 1. If target is not null, a NotSupportedException is thrown.
' 2. If target is null, then Copy is called and the new object is returned.
Public Overrides Function Union(ByVal target As IPermission) As IPermission
' If 'target' is null, then return a copy of 'this'.
If target Is Nothing Then
Return Copy()
End If
' Both objects must be the same type.
Dim soundPerm As SoundPermission = VerifyTypeMatch(target)
' If 'this' or 'target' are unrestricted, return a new unrestricted permission.
If m_specifiedAsUnrestricted OrElse soundPerm.m_specifiedAsUnrestricted Then
Return Clone(True, SoundPermissionState.PlayAnySound)
End If
' Return a new object with the calculated, unioned permission value.
Return Clone(False, CType(Math.Max(CType(m_flags, Int32), CType(soundPerm.m_flags, Int32)), SoundPermissionState))
