[RESOLVED] [2005] For...Next vs. Do...While

[Troy Lundin]

When I open my assemblies in Reflector, my for...next loops are rewritten like so:

Original Loop:

For i As Int32 = 0 To 30 Step 1
' Do something
Next i

Rewritten Loop:

Dim i As Integer
Do While (i <= 30)
' Do something
i += 1
Loop

I have also seen (and used):

Dim i As Integer
Do
' Do something
i += 1
Loop While (i <= 30)

Is there any performance difference between those? Or any difference other than the obvious aesthetic one?
