That's the official way.
Note that the string is not parsable. It's only suitable for
About-dialogs or similar purposes (bug reports etc.):

using System;
using System.Reflection;

class T
	static void Main ()
		Console.WriteLine (GetDisplayName ());

	// Returns the display name of the current runtime.
	static string GetDisplayName ()
		Type t = Type.GetType ("Mono.Runtime");
		if (t == null) return "MS.NET";

		MethodInfo mi = t.GetMethod ("GetDisplayName",
			BindingFlags.Static | BindingFlags.NonPublic);
		return (string) mi.Invoke (null, null);
