what is Using keyword in VB.net ?
-
hello ! can u tell me what is Using keyword in VB.net ? what it do ? and if i want to write a keyword like this in C#, which keyword should i use ?
The Using keyword simply sticks a Dispose call at the end of the code. For example:
Using(sw As New StreamWriter("C:/TestFile.txt"))
sw.WriteLine("Aloha!")
End Usingbecomes
Try
Dim sw As New StreamWriter("C:/TestFile.txt")sw.WriteLine("Aloha!")Finally
sw.Dispose()
End TryThe keyword in C# is
using; it's case sensitive, unlike VB.NetBetween the idea And the reality Between the motion And the act Falls the Shadow

It does more for you than just call
Disposein the manner in which you describe. It also wraps it in aTry/Finallyblock too so thatDisposeis always called even in the event that an exception is raised. This is where its real usefulness lies. It is much easier to write theUsingblock that it would two write all the corresponsingTry/Finallystuff to do the same thing.User group: Scottish Developers Blog: Can Open... Worms? Everywhere!
