DnsPermission.IsUnrestricted Method

Checks the overall permission state of the object.

Namespace: System.Net
Assembly: System (in system.dll)

'Declaration
Public Function IsUnrestricted As Boolean
'Usage
Dim instance As DnsPermission
Dim returnValue As Boolean

returnValue = instance.IsUnrestricted
public final boolean IsUnrestricted ()
public final function IsUnrestricted () : boolean
Not applicable.

Return Value

true if the DnsPermission instance was created with PermissionState.Unrestricted; otherwise, false.

The following example uses the IsUnrestricted method to check the overall permission state of the object.

Public Sub useDns()
    ' Create a DnsPermission instance.
    Dim permission As New DnsPermission(PermissionState.Unrestricted)
    ' Check for permission.
    permission.Demand()
    Console.WriteLine("Attributes and Values of DnsPermission instance :")
    ' Print the attributes and values.
    PrintKeysAndValues(permission.ToXml().Attributes)
    ' Check the permission state.
    If permission.IsUnrestricted() Then
        Console.WriteLine("Overall permissions : Unrestricted")
    Else
        Console.WriteLine("Overall permissions : Restricted")
    End If
End Sub 'useDns
 
Private Sub PrintKeysAndValues(myList As Hashtable)
    ' Get the enumerator that can iterate through the hash table.
    Dim myEnumerator As IDictionaryEnumerator = myList.GetEnumerator()
    Console.WriteLine(ControlChars.Tab + "-KEY-" + ControlChars.Tab + "-VALUE-")
    While myEnumerator.MoveNext()
        Console.WriteLine(ControlChars.Tab + "{0}:" + ControlChars.Tab + "{1}", myEnumerator.Key, myEnumerator.Value)
    End While
    Console.WriteLine()
End Sub 'PrintKeysAndValues

public void UseDns()
{
    // Create a DnsPermission instance.
    DnsPermission permission = 
        new DnsPermission(PermissionState.Unrestricted);

    // Check for permission.
    permission.Demand();
    Console.WriteLine("Attributes and Values of DnsPermission instance :");

    // Print the attributes and values.
    PrintKeysAndValues(permission.ToXml().get_Attributes());

    // Check the permission state.
    if (permission.IsUnrestricted()) {
        Console.WriteLine("Overall permissions : Unrestricted");
    }
    else {
        Console.WriteLine("Overall permissions : Restricted");
    }
} //UseDns

private void PrintKeysAndValues(Hashtable myList)
{
    // Get the enumerator that can iterate through the hash table.
    IDictionaryEnumerator myEnumerator = myList.GetEnumerator();
    Console.WriteLine("\t-KEY-\t-VALUE-");
    while (myEnumerator.MoveNext()) {
        Console.WriteLine("\t{0}:\t{1}", myEnumerator.get_Key(),
            myEnumerator.get_Value());
    }
    Console.WriteLine();
} //PrintKeysAndValues
