Split a number into its composite digits and count.

Try..

$Num = "345"
($num -split "" | Measure -Sum).Sum

Select allOpen in new window

Doesnt seem to work, I have the following...

for($i = 1; $i -lt 100; $i++) {
 $current = "$i"
 ($current.Split("") | Measure-Object -Sum).Sum
}

But this isnt returning the results I would expect...

Note: I had to use $current.Split("") to make the code compile...

Use the -split operator as Subsun posted, not the split method.

for($i = 1; $i -lt 100; $i++) {
 $current = $i
 ($current -Split "" | Measure-Object -Sum).Sum
}

Select allOpen in new window

Unfortunately when I try that command I get a 'You must provide a value expression on the right-hand side of the '-' operator.

Then you probably have a space after a hyphen somewhere.  Select all the code above and paste and run.

I think it must be something more sinister... I copied and pasted the following into a new window...

$num = "345"
($num -split "" | Measure -Sum).Sum

And am still getting the same issue?

EXCEPTION TYPE: System.Management.Automation.ParseException

Good call, I am using powershell v1.0.0.0 - your final solution worked like a charm. Thanks for the help! Perhaps its time I move onto the latest version of powershell!
