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

You don't necessarily have to use the [string]:: prefix. This works in the same way:

if ($version)
{
    $request += "/" + $version
}

A variable that is null or empty string evaluates to false.
