The scope of the declaration that is allowed depends on the SecurityAction that is used.
The security information declared by a security attribute is stored in the metadata of the attribute target and is accessed by the system at run time. Security attributes are used only for declarative security. For imperative security, use the corresponding permission class.
The following example of a declarative attribute shows the correct way to request ZoneIdentityPermission and states that you must have at least this permission to run your code. Code will run only if executed from the local computer.
<assembly: ZoneIdentityPermissionAttribute(SecurityAction.RequestMinimum, _
Zone := SecurityZone.MyComputer)>
'In Visual Basic, you must specify that you are using the assembly scope when making a request.
/** @assembly ZoneIdentityPermissionAttribute(SecurityAction.RequestMinimum,
Zone = SecurityZone.MyComputer)
*/
// In VJ#, you must specify that you are using the assembly scope when making
// a request.
The following example shows how to demand that the calling code has ZoneIdentityPermission at link time. Code will run only if executed from the local computer.
<ZoneIdentityPermissionAttribute(SecurityAction.Demand, _ Zone := SecurityZone.MyComputer)> Public Class SampleClass
/** @attribute ZoneIdentityPermissionAttribute(SecurityAction.Demand,
Zone = SecurityZone.MyComputer)
