Remarks

The HttpPostedFileBase class is an abstract class that contains the same members as the HttpPostedFile class. The HttpPostedFileBase class lets you create derived classes that are like the HttpPostedFile class, but that you can customize and that work outside the ASP.NET pipeline. When you perform unit testing, you typically use a derived class to implement members that have customized behavior that fulfills the scenario you are testing.

The HttpPostedFileWrapper class derives from the HttpPostedFileBase class. The HttpPostedFileWrapper class serves as a wrapper for the HttpPostedFile class. At run time, you typically use an instance of the HttpPostedFileWrapper class to call members of the HttpPostedFile object.
