Voorbeelden

In het volgende voorbeeld ziet u de Message eigenschap. Dit codevoorbeeld maakt deel uit van een groter voorbeeld voor de MissingMemberException klasse.

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.
    typeof<App>.InvokeMember("AnotherField", BindingFlags.Static ||| BindingFlags.GetField, null, null, null)
    |> ignore
with :? MissingMemberException as 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.
    printfn $"Unable to access the AnotherField field: {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

Opmerkingen

Als de klassenaam niet is opgegeven wanneer het object wordt samengesteld, wordt de standaardteksttekenreeks die is overgenomen van de basisklasse, geretourneerd.

Deze eigenschap overschrijft Message. Het foutbericht moet worden gelokaliseerd.

Deze eigenschap is alleen-lezen.
