Hi all VFP'ers,
As you probably know by now X# plans to have VFP syntax support by
October 2019.
A question I am asked a lot by VFP coders is: Do I have to strict type
my code in X#? Well, X# allows both lazy declaration and strict declaration.
Here is a small benchmark to compare the results:
function Start( ) as void
local nWeak
local nStrongas int
local dStartas DateTime
System.Console.WriteLine("Starting, non typed")&& The .NET way of "?
<Expressions>"
dStart :=DateTime.Now
for nWeak := 1to 10000000
nop&& A X# way of saying No operating procedures, will not produce a
compiler warning message
next
System.Console.WriteLine("Terminated, non typed, duration " + (DateTime.Now
- dStart ):ToString() )
System.Console.WriteLine("Starting, typed")
dStart :=DateTime.Now
for nStrong := 1to 10000000
nop
next
System.Console.WriteLine("Terminated, typed, duration " + (DateTime.Now -
dStart ):ToString() )
return
&& Results:
&& Starting, non typed
&& Terminated, non typed, duration 00:00:00.6469739
&& Starting, typed
&& Terminated, typed, duration 00:00:00.0210397
&& A speed improvement of 30.75 times
Hope this is of interest to some.
