Exemples

L’exemple suivant illustre la Message propriété. Cet exemple de code fait partie d’un exemple plus grand fourni pour la MissingMethodException classe.

try
{
    // Attempt to call a static DoSomething method defined in the App class.
    // However, because the App class does not define this method,
    // a MissingMethodException is thrown.
    App::typeid->InvokeMember("DoSomething", BindingFlags::Static |
        BindingFlags::InvokeMethod, nullptr, nullptr, nullptr);
}
catch (MissingMethodException^ ex)
{
    // Show the user that the DoSomething method cannot be called.
    Console::WriteLine("Unable to call the DoSomething method: {0}",
        ex->Message);
}

try
{
    // Attempt to call a static DoSomething method defined in the App class.
    // However, because the App class does not define this method,
    // a MissingMethodException is thrown.
    typeof(App).InvokeMember("DoSomething", BindingFlags.Static |
        BindingFlags.InvokeMethod, null, null, null);
}
catch (MissingMethodException e)
{
    // Show the user that the DoSomething method cannot be called.
    Console.WriteLine("Unable to call the DoSomething method: {0}", e.Message);
}

try
    // Attempt to call a static DoSomething method defined in the App class.
    // However, because the App class does not define this method,
    // a MissingMethodException is thrown.
    typeof<App>.InvokeMember("DoSomething", BindingFlags.Static ||| BindingFlags.InvokeMethod, null, null, null)
    |> ignore
with :? MissingMethodException as e ->
    // Show the user that the DoSomething method cannot be called.
    printfn $"Unable to call the DoSomething method: {e.Message}"

Try
    ' Attempt to call a static DoSomething method defined in the App class.
    ' However, because the App class does not define this method, 
    ' a MissingMethodException is thrown.
    GetType(App).InvokeMember("DoSomething", BindingFlags.Static Or BindingFlags.InvokeMethod, _
                               Nothing, Nothing, Nothing)
Catch e As MissingMethodException
    ' Show the user that the DoSomething method cannot be called.
    Console.WriteLine("Unable to call the DoSomething method: {0}", e.Message)
End Try

Remarques

Si le nom de classe n’est pas spécifié lorsque l’objet est construit, la chaîne de texte par défaut héritée de la classe de base est retournée.

Cette propriété remplace Message. Le message d’erreur doit être localisé.
