PermissionSet Constructor (PermissionState)


The .NET API Reference documentation has a new home. Visit the .NET API Browser on to see the new experience.

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

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

Public Sub New (
	state As PermissionState


Type: System.Security.Permissions.PermissionState

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

Exception Condition

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.
Dim ps1 As 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.")
Console.WriteLine("Demand succeeded.")
