Definition

Namespace:

System.Security

Assembly:

System.Runtime.dll

Source:

PermissionSet.cs

Adds a specified permission to the PermissionSet.

public:
 System::Security::IPermission ^ AddPermission(System::Security::IPermission ^ perm);

public System.Security.IPermission? AddPermission (System.Security.IPermission? perm);

member this.AddPermission : System.Security.IPermission -> System.Security.IPermission

Public Function AddPermission (perm As IPermission) As IPermission

Parameters

perm

IPermission

The permission to add.

Returns

IPermission

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

Exceptions

InvalidOperationException

The method is called from a ReadOnlyPermissionSet.

Examples

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.
ps1.AddPermission(
    new FileDialogPermission(FileDialogPermissionAccess.Open));

' Add a permission to the permission set.
ps1.AddPermission(New FileDialogPermission(FileDialogPermissionAccess.Open))

Remarks

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 Unrestricted PermissionSet.

Notes to Inheritors

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