If strings starts with in PowerShell
<p>Is there a way to check if a string starts with a string?</p>

<p>We are checking the groupmembership from the <a href="http://en.wikipedia.org/wiki/Active_Directory" rel="noreferrer">AD</a> user. Our AD groups look like this: <code>S_G_share1_W</code></p>

<p>The script for connecting the networkshares should only run if the groupname starts with <code>"S_G_"</code>, because we have some other groups too.</p>

<pre><code>$GroupArray = Get-ADPrincipalGroupMembership $env:USERNAME | select samaccountname

foreach ($Group in $GroupArray) {

    if ($Group.StartsWith("S_G_")) {

        $Group = $Group -replace "S_G_", $FileServerRV
        Write-Host $Group

        $Group = $Group.Substring(0, $Group.Length-2)
        Write-Host $Group

        #erstellen des Anzeigennames
        $Groupname = $Group.Replace($FileServerRV, "")
        Write-Host "Call Function with parameter "$Group $Groupname
    }
}
</code></pre>
