using
The using
statement is very useful if you are working with objects that need to be disposed by the garbage collector at a defined point.
using System.IO using System.Text function Start( ) as void local cFileName as string local aBytes as byte[] cFileName := "c:\temp\Using.txt" System.Console.WriteLine("start working with" + cFileName ) begin using var oFile := FileStream{ cFileName, FileMode.OpenOrCreate, FileAccess.ReadWrite } // as FileStream aBytes := Encoding.ASCII.GetBytes( "Hello world!" ) oFile:Write( aBytes, 0, aBytes:Length ) end using // file is not only out of scope, but also disposed, i.e. closed System.Console.WriteLine("end working with" + cFileName ) System.Console.Write( "press a key...." ) System.Console.ReadKey() return
