While Loop in VB.net
By: Ramlak in VB.net Tutorials on 2008-11-25
While loops keep looping while the condition they test remains true, so you use a While loop if you have a condition that will become false when you want to stop looping. Here's the While loop's syntax (note that you used to end this loop with Wend in VB6 and before-that's changed to End While now):
While condition
[statements]
End While
And here's an example putting While to work:
Sub CheckWhile() Dim intCounter As Integer = 0 Dim intNumber As Integer = 10 While intNumber > 6 intNumber -= 1 intCounter += 1 End While MsgBox("The loop ran " & intCounter & " times.") End Sub
And here's what you see when you run this code:
The loop ran 4 times. Press any key to continue

Many Visual Basic functions, like EOF-which is true when you've reached the end of a file while reading from it-are explicitly constructed to return values of True or False so that you can use them to control loops such as Do and While loops. |
