PermissionSet.AddPermission(IPermission) Method


Adds a specified permission to the PermissionSet.

 virtual System::Security::IPermission ^ AddPermission(System::Security::IPermission ^ perm);
public virtual System.Security.IPermission AddPermission (System.Security.IPermission perm);
abstract member AddPermission : System.Security.IPermission -> System.Security.IPermission
override this.AddPermission : System.Security.IPermission -> System.Security.IPermission
Public Overridable Function AddPermission (perm As IPermission) As IPermission



The permission to add.


The union of the permission added and any permission of the same type that already exists in the PermissionSet.


The method is called from a ReadOnlyPermissionSet.


The following code example shows the use of the AddPermission method to add a permission to a permission set. This code example is part of a larger example provided for the PermissionSet class.

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


If a permission of the same type as the added permission already exists in the PermissionSet, the new permission is the union of the existing permission object and the specified permission object. For example, if a permission that implements IUnrestrictedPermission is added to an UnrestrictedPermissionSet, the resulting union is the original UnrestrictedPermissionSet.

Notes to Inheritors

When you inherit from PermissionSet, you can change the behavior of the AddPermission(IPermission) method by overriding the AddPermissionImpl(IPermission) method.
