PermissionSet Constructor (PermissionState)

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

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

public PermissionSet (
	PermissionState state
)
public PermissionSet (
	PermissionState state
)
public function PermissionSet (
	state : PermissionState
)

Parameters

state

One of the PermissionState values.

Exception typeCondition

ArgumentException

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 = new 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(
    new FileDialogPermission(FileDialogPermissionAccess.Open));
Console.WriteLine("Demanding permission to open a file.");
ps1.Demand();
Console.WriteLine("Demand succeeded.");

// Open a new PermissionSet.
PermissionSet ps1 = new 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(new FileDialogPermission(
    FileDialogPermissionAccess.Open));

Console.WriteLine("Demanding permission to open a file.");
ps1.Demand();
Console.WriteLine("Demand succeeded.");
