PowerShell Loops Do
Example
Do-loops are useful when you always want to run a codeblock at least once. A Do-loop will evaluate the condition after executing the codeblock, unlike a while-loop which does it before executing the codeblock.
You can use do-loops in two ways:
-
Loop while the condition is true:
Do { code_block } while (condition) -
Loop until the condition is true, in other words, loop while the condition is false:
Do { code_block } until (condition)
Real Examples:
$i = 0
Do {
$i++
"Number $i"
} while ($i -ne 3)
Do {
$i++
"Number $i"
} until ($i -eq 3)
Do-While and Do-Until are antonymous loops. If the code inside the same, the condition will be reversed. The example above illustrates this behaviour.
