FileIOPermission::IsSubsetOf Method (IPermission^)

 

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

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

public:
virtual bool IsSubsetOf(
	IPermission^ target
) override

Parameters

target
Type: System.Security::IPermission^

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

Return Value

Type: System::Boolean

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

Exception Condition
ArgumentException

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

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