PermissionSet.IsSubsetOf(PermissionSet) PermissionSet.IsSubsetOf(PermissionSet) PermissionSet.IsSubsetOf(PermissionSet) PermissionSet.IsSubsetOf(PermissionSet) Method

Definition

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

public:
 bool IsSubsetOf(System::Security::PermissionSet ^ target);
public bool IsSubsetOf (System.Security.PermissionSet target);
member this.IsSubsetOf : System.Security.PermissionSet -> bool
Public Function IsSubsetOf (target As PermissionSet) As Boolean
Parameters
target
PermissionSet PermissionSet PermissionSet PermissionSet

The permission set to test for the subset relationship. This must be either a PermissionSet or a NamedPermissionSet.

Returns

true if the current PermissionSet is a subset of the target parameter; otherwise, false.

Examples

The following code example shows the use of the IsSubsetOf method. This code example is part of a larger example provided for the PermissionSet class.

   // Create a second permission set and compare it to the first permission set.
   ps2->AddPermission( gcnew EnvironmentPermission( EnvironmentPermissionAccess::Read,"USERNAME" ) );
   ps2->AddPermission( gcnew EnvironmentPermission( EnvironmentPermissionAccess::Write,"COMPUTERNAME" ) );
IEnumerator^ list =  ps1->GetEnumerator();
Console::WriteLine("Permissions in first permission set:");
         while (list->MoveNext())
	Console::WriteLine(list->Current->ToString());
   Console::WriteLine( "Second permission IsSubsetOf first permission = {0}", ps2->IsSubsetOf( ps1 ) );
// Create a second permission set and compare it to the first permission set.
ps2.AddPermission(
    new EnvironmentPermission(EnvironmentPermissionAccess.Read, "USERNAME"));
ps2.AddPermission(
    new EnvironmentPermission(EnvironmentPermissionAccess.Write, "COMPUTERNAME"));
IEnumerator list =  ps1.GetEnumerator();
Console.WriteLine("Permissions in first permission set:");
while (list.MoveNext())
    Console.WriteLine(list.Current.ToString());
Console.WriteLine("Second permission IsSubsetOf first permission = " + ps2.IsSubsetOf(ps1));
' Create a second permission set and compare it to the first permission set.
ps2.AddPermission(New EnvironmentPermission(EnvironmentPermissionAccess.Read, "USERNAME"))
ps2.AddPermission(New EnvironmentPermission(EnvironmentPermissionAccess.Write, "COMPUTERNAME"))
Console.WriteLine("Permissions in first permission set:")
Dim list As IEnumerator = ps1.GetEnumerator()
While list.MoveNext()
    Console.WriteLine(list.Current.ToString())
End While
Console.WriteLine("Second permission IsSubsetOf first permission = " & ps2.IsSubsetOf(ps1))

Remarks

A PermissionSet is a subset of the target PermissionSet if all demands that succeed for the PermissionSet also succeed for the target. That is, the target contains at least the permissions contained in the subset.
