名前空間: System.Net
アセンブリ: System (system.dll 内)
構文

Visual Basic (宣言)

Public Function IsUnrestricted As
 Boolean

Visual Basic (使用法)

Dim instance As DnsPermission
Dim returnValue As Boolean

returnValue = instance.IsUnrestricted

C#

public bool IsUnrestricted ()

C++

public:
virtual bool IsUnrestricted () sealed

戻り値
DnsPermission インスタンスが PermissionState.Unrestricted で作成された場合は true。それ以外の場合は false。

使用例

IsUnrestricted メソッドを使用して、オブジェクトの全般的なアクセス許可状態をチェックする例を次に示します。

Visual Basic

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

C#

   // 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();
}

C++

   }

private:

         Console::WriteLine( "\t {0}:\t {1}", myEnumerator->Key, myEnumerator->Value
 );
      }
      Console::WriteLine();
   }

J#

public void UseDns()

    // 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(),
