EnvironmentPermission.IsSubsetOf(IPermission) Method

Definition

Determines whether the current permission is a subset of the specified permission.

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

Parameters

target
IPermission

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

Returns

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

Exceptions

The target parameter is not null and is not of the same type as the current permission.

Remarks

The current permission is a subset of the specified permission if the current permission specifies a state that is wholly contained by the specified permission. 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 represents no more access to the protected resource than does the specified permission.
