Basic File Functions
---------------------
Read File:
----------
Imports System
Imports System.IO
Public Module modmain
  Sub Main()
   Dim srFile as StreamReader = File.OpenText("C:\autoexec.bat")
   Console.WriteLine(srFile.ReadToEnd())
   srFile.Close
  End Sub
End Module
Write File:
-----------
Imports System
Imports System.IO
Public Module modmain
  Sub Main()
   Dim swFile as StreamWriter = File.CreateText("C:\test.txt")
   swFile.WriteLine("Hello World ;)")
   swFile.Flush()
   swFile.Close()
  End Sub
End Module
File Version Info:
------------------
Imports System
Imports System.Diagnostics
Public Module modmain
  Sub Main()
   Dim versionInfo As FileVersionInfo = FileVersionInfo.GetVersionInfo("C:\WINNT\Notepad.exe")
   Console.WriteLine("Notepad version " + versionInfo.FileVersion)
   Console.WriteLine("Description: " + versionInfo.FileDescription)
  End Sub
End Module
File Size:
----------
Imports System
Imports System.IO
Public Module modmain
  Sub Main()
   Dim MyFile as new FileInfo ("c:\autoexec.bat")
   Console.WriteLine("The length of autoexec.bat is " _
     + MyFile.Length.ToString + " bytes.")
  End Sub
End Module
Copy Move and Delete File:
--------------------------
Imports System
Imports System.IO
Public Module modmain
  Sub Main()
   	File.Copy("c:\autoexec.bat", "c:\autocopy.ext")
   	File.Move("c:\autocopy.ext", "c:\newname.ext")
	File.Delete("c:\autocopy.ext")
  End Sub
End Module
Temporary File Name:
---------------------
The GetTempFileName function creates a name for a temporary file. The filename is the concatenation of specified path and prefix strings, a hexadecimal string formed from a specified integer, and the .TMP extension.
Imports System
Imports System.IO
Public Module modmain
  Sub Main()
   Console.WriteLine(Path.GetTempFileName)
  End Sub
End Module
