What is the Linq.First equivalent in PowerShell?

Question

The snippet below detects from a list of files which of them is a Directory on Ftp

as C# it will be like below

var files = new List(){\"App         


        

Answer 1

This is a really simple implementation for First:

function First($collection)
{
    foreach ($item in $collection)
    {
        return $item
    }
    return $null
}

Instead of returning $null, you could throw an InvalidOperationException exception.
