VB.NET Core Classes in a Nutshell

Name

File

Synopsis

Like the Directory type, this type offers a collection of shared utility methods for working with files on the filesystem. In most cases, these methods are simply shortcuts for working with the System.IO types directly; for example, the AppendText() method returns a StreamWriter that can append text to the file specified in the path argument. This could be accomplished just as easily by creating a StreamWriter around a FileStream opened to the same file, with the FileMode.Append flag passed into the constructor.

That stated, there are methods on this type that aren’t available through the Stream-based API. For example, the file’s creation time, last-accessed time, last-modified times, and attributes, are all available via this type, whereas no such corresponding call exists on the Stream type.
