SmtpPermissionAttribute.CreatePermission Method
Creates a permission object that can be stored with the SecurityAction in an assembly's metadata.
Namespace: System.Net.Mail
Assembly: System (in System.dll)
This method should only be called by the security system, never by application code.
At compile time, attributes are converted into security declarations and stored in Microsoft intermediate language (MSIL) metadata. At run time, the security declarations in metadata are used to create permission objects that map to the state described in the metadata.
