SecurityException.PermitOnlySetInstance Property

Gets or sets the permission, permission set, or permission set collection that is part of the permit-only stack frame that caused a security check to fail.

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

[ComVisibleAttribute(false)]
public Object PermitOnlySetInstance { get; set; }

Property Value

Type: System.Object
A permission, permission set, or permission set collection object.

The PermitOnlySetInstance property represents the permitted permission, permission set, or permission set collection contained in the stack frame that caused the security exception. For instance, when a security exception occurs because of a PermissionSet.Demand failure, the permitted permission appears in this property and the demanded PermissionSet is contained in the Demanded property.

This property is of type Object because permissions, permission sets, or permission set collections can all be demanded and Object is their common base class. To test the run-time type of this property, you can use the GetType method or a specific language operator, such as the is operator in C# or the TypeOf operator in Visual Basic.

The following code example shows the use of the PermitOnlySetInstance property to display the permission, permission set, or permission set collection that is part of the permit-only stack frame that caused a security check to fail. This code example is part of a larger example provided for the SecurityException class.

Display("The permitted permission is: " +
    ((PermissionSet)sE.PermitOnlySetInstance).ToString());
