Updated Code

To retrieve the version number from the assembly in your code, you use can do this:

String strVersion = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString(); 

To retrieve the version number from the assembly that is calling your assembly, you can use this:

String strVersion = System.Reflection.Assembly.GetCallingAssembly().GetName().Version.ToString();

Initial Code

See the To retrieve the version number from the assembly in your code, you use can do this:

String strVersion = System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString(); 

To retrieve the version number from the assembly that is calling your assembly, you can use this:

String strVersion = System.Reflection.Assembly.GetCallingAssembly().GetName().Version.ToString();

Initial Description

If you are just looking for the version information in the assembly, you can use `Application.ProductVersion` (at least for GUI applications). I don't think you'll get the reflection performance hit this way.

You can also add an "About" box to your GUI and see what code is generated for all of that information (product name, copyright, version, etc).
