At this point, you can run your application. When you select the CSharpSnapIn.dll or

VbNetSnapIn.dll assemblies, you should see the correct message displayed. The final task is to dis-

to call a new helper function named DisplayCompanyData() before exiting the foreach scope. Notice

this method takes a single System.Type parameter.
