DBDataPermission.IsSubsetOf(IPermission) Method

Definition

Namespace:

System.Data.Common

Assembly:

System.Security.Permissions.dll

Source:

DBDataPermission.cs

Returns a value indicating whether the current permission object is a subset of the specified permission object.

C#

public override bool IsSubsetOf(System.Security.IPermission target);

Parameters

target

IPermission

A permission object that is to be tested for the subset relationship. This object must be of the same type as the current permission object.

Returns

Boolean

true if the current permission object is a subset of the specified permission object, otherwise false.

Exceptions

ArgumentException

The target parameter is an object that is not of the same type as the current permission object.

Remarks

The current permission object is a subset of the specified permission object if the current permission object specifies a set of operations that is wholly contained by the specified permission object. For example, a permission that represents access to C:\example.txt is a subset of a permission that represents access to C:\. If this method returns true, the current permission object represents no more access to the protected resource than does the specified permission object.
