The ProcessStartInfo.Verbs property enables you to determine the verbs that can be used with the file specified by the ProcessStartInfo.FileName property. You can set the ProcessStartInfo.Verb property to the value of any verb in the set. Examples of verbs are "Edit", "Open", "OpenAsReadOnly", "Print", and "Printto".

When you use the ProcessStartInfo.Verbs property, you must include the file name extension when you set the value of the ProcessStartInfo.FileName property. The file name extension determines the set of possible verbs.
