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

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

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.Key, myEnumerator.Value);
   Console.WriteLine();
}

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
