Check if a string is not NULL or EMPTY

Question

In below code, I need to check if version string is not empty then append its value to the request variable.

if ([string]::IsNullOrEmpty($version))
{
    $re         


        

Answer 1

I would define $Version as a string to start with

[string]$Version

and if it's a param you can use the code posted by Samselvaprabu or if you would rather not present your users with an error you can do something like

while (-not($version)){
    $version = Read-Host "Enter the version ya fool!"
}
$request += "/" + $version
