PermissionSet Constructor (PermissionState)

Initializes a new instance of the PermissionSet class with the specified PermissionState.

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

	PermissionState state


Type: System.Security.Permissions::PermissionState

One of the enumeration values that specifies the permission set's access to resources.


The state parameter is not a valid PermissionState.

The Unrestricted state allows all permissions that implement the IUnrestrictedPermission interface, while None allows no permissions.

Use AddPermission on an empty PermissionSet to define the set in greater detail.

The following code example shows the use of the PermissionSet constructor to create a permission set with a permission state of None. This code example is part of a larger example provided for the PermissionSet class.

// Open a new PermissionSet.
PermissionSet^ ps1 = gcnew PermissionSet( PermissionState::None );

Console::WriteLine( "Adding permission to open a file from a file dialog box." );

// Add a permission to the permission set.
ps1->AddPermission( gcnew FileDialogPermission( FileDialogPermissionAccess::Open ) );

Console::WriteLine( "Demanding permission to open a file." );
Console::WriteLine( "Demand succeeded." );
