Access localized resource strings without creating an instance of 'ResourceManager'?

Question

I have created some resource files to hold strings. I am displaying a MessageBox by pointing it directly at a resource file named TestLocalResource

You don't need to use the ResourceManager explicitly.
Have a look here: http://geekswithblogs.net/mapfel/archive/2008/11/01/126465.aspx
To learn how to change the culture to use during runtime, see the second comment in the link:

switch (comboBox1.Text)
{
    case "neutral":
        Thread.CurrentThread.CurrentUICulture = new CultureInfo("");
        break;
    case "en-GB":
        Thread.CurrentThread.CurrentUICulture = new CultureInfo("en-GB");
        break;
    case "de-DE":
        Thread.CurrentThread.CurrentUICulture = new CultureInfo("de-DE");
        break;
}

string messageText = Messages.MsgSampleText;
MessageBox.Show(messageText);
