The System.IO.File Class

The System.IO.File class provides access to files on disk exposing special shared members. For example, you can easily create a text file invoking two methods: WriteAllText and WriteAllLines. Both create a new text file, put into the file the given text, and then close the file; however, the second one enables you to write the content of an array of strings into multiple lines. The following code provides an example:

File.WriteAllText("C:\Temp\OneFile.txt", "Test message")Dim lines() As String = {"First", "Second", "Third"}File.WriteAllLines("C:\Temp\OneFile.txt", lines)

Such methods are useful because they avoid the need to manually close files on disk when you perform the writing operation. ...
