SecurityPermissionAttribute Constructor

Initializes a new instance of the SecurityPermissionAttribute class with the specified SecurityAction.

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

public SecurityPermissionAttribute (
	SecurityAction action
)
public SecurityPermissionAttribute (
	SecurityAction action
)
public function SecurityPermissionAttribute (
	action : SecurityAction
)

Parameters

action

One of the SecurityAction values.

The following code example shows the use of the SecurityPermissionAttribute constructor to create instances of the SecurityPermissionAttribute class that are used to deny and demand security permissions.

// This sample demonstrates the use of the SecurityPermissionAttribute.
