PermissionSet::AddPermission Method (IPermission^)

 

Adds a specified permission to the PermissionSet.

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

public:
IPermission^ AddPermission(
	IPermission^ perm
)

Parameters

perm
Type: System.Security::IPermission^

The permission to add.

Return Value

Type: System.Security::IPermission^

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

Exception Condition
InvalidOperationException

The method is called from a ReadOnlyPermissionSet.

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 method by overriding the AddPermissionImpl method.

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 ) );
