Examples

The following example demonstrates the Message property. This code example is part of a larger example provided for the MissingFieldException class.

try
{
    // Attempt to access a static AField field defined in the App class.
    // However, because the App class does not define this field,
    // a MissingFieldException is thrown.
    App::typeid->InvokeMember("AField", BindingFlags::Static |
        BindingFlags::SetField, nullptr, nullptr, gcnew array<Object^>{5});
}
catch (MissingFieldException^ ex)
{
    // Show the user that the AField field cannot be accessed.
    Console::WriteLine("Unable to access the AField field: {0}",
        ex->Message);
}

try
{
    // Attempt to access a static AField field defined in the App class.
    // However, because the App class does not define this field,
    // a MissingFieldException is thrown.
    typeof(App).InvokeMember("AField", BindingFlags.Static | BindingFlags.SetField,
        null, null, new Object[] { 5 });
}
catch (MissingFieldException e)
{
 // Show the user that the AField field cannot be accessed.
 Console.WriteLine("Unable to access the AField field: {0}", e.Message);
}

try
    // Attempt to access a static AField field defined in the App class.
    // However, because the App class does not define this field,
    // a MissingFieldException is thrown.
    typeof<App>.InvokeMember("AField", BindingFlags.Static ||| BindingFlags.SetField, null, null, [| box 5 |])
    |> ignore
with :? MissingFieldException as e ->
    // Show the user that the AField field cannot be accessed.
    printfn $"Unable to access the AField field: {e.Message}"

Try
    ' Attempt to access a static AField field defined in the App class.
    ' However, because the App class does not define this field, 
    ' a MissingFieldException is thrown.
    GetType(App).InvokeMember("AField", BindingFlags.Static Or BindingFlags.SetField, _
                               Nothing, Nothing, New [Object]() {5})
Catch e As MissingFieldException
    ' Show the user that the AField field cannot be accessed.
    Console.WriteLine("Unable to access the AField field: {0}", e.Message)
End Try

Remarks

If the class name is not specified when the object is constructed, the default text string inherited from the base class is returned. This property overrides Message. The error message should be localized.
