title: Ability to find WinForm control via the Tag property
body: <p>I am working in C# on an existing WinForm project.  The original code uses Tag to convey hardware addressing info for a bunch of textboxes that represent certain hardware registers in a connected microcontroller system.  I know how to find an unknown control by searching for its Name using the Control.ControlCollection.Find method, but it's unclear to me on whether I can find the control by the Tag (just a string in this instance).</p>
