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
