Beispiele

Im folgenden Beispiel wird die Message-Eigenschaft veranschaulicht.The following example demonstrates the Message property. Dieses Codebeispiel ist Teil eines größeren Beispiels, das für die MissingMemberException-Klasse bereitgestellt wird.This code example is part of a larger example provided for the MissingMemberException class.

try
{
    // Attempt to access a static AnotherField field defined in the App class.
    // However, because the App class does not define this field,
    // a MissingFieldException is thrown.
    App::typeid->InvokeMember("AnotherField", BindingFlags::Static |
        BindingFlags::GetField, nullptr, nullptr, nullptr);
}
catch (MissingMemberException^ ex)
{
    // Notice that this code is catching MissingMemberException which is the
    // base class of MissingMethodException and MissingFieldException.
    // Show the user that the AnotherField field cannot be accessed.
    Console::WriteLine("Unable to access the AnotherField field: {0}",
        ex->Message);
}
try
{
    // Attempt to access a static AnotherField field defined in the App class.
    // However, because the App class does not define this field,
    // a MissingFieldException is thrown.
    typeof(App).InvokeMember("AnotherField", BindingFlags.Static |
        BindingFlags.GetField, null, null, null);
}
catch (MissingMemberException e)
{
 // Notice that this code is catching MissingMemberException which is the
 // base class of MissingMethodException and MissingFieldException.
 // Show the user that the AnotherField field cannot be accessed.
 Console.WriteLine("Unable to access the AnotherField field: {0}", e.Message);
}
    Try
        ' Attempt to access a static AnotherField field defined in the App class.
        ' However, because the App class does not define this field, 
        ' a MissingFieldException is thrown.
        GetType(App).InvokeMember("AnotherField", BindingFlags.Static Or BindingFlags.GetField, _
                                   Nothing, Nothing, Nothing)
    Catch e As MissingMemberException
        ' Notice that this code is catching MissingMemberException which is the  
        ' base class of MissingMethodException and MissingFieldException.
        ' Show the user that the AnotherField field cannot be accessed.
        Console.WriteLine("Unable to access the AnotherField field: {0}", e.Message)
    End Try
End Sub 

Hinweise

Wenn der Klassenname beim Konstruieren des Objekts nicht angegeben wird, wird die von der Basisklasse geerbte Standardtext Zeichenfolge zurückgegeben.If the class name is not specified when the object is constructed, the default text string inherited from the base class is returned.

Diese Eigenschaft überschreibt Message.This property overrides Message. Die Fehlermeldung sollte lokalisiert werden.The error message should be localized.
