How to print modifications in repository, using SharpSVN DLL in PowerShell?

Question

I am using SharpSvn DLL in PowerShell. I've got as far as updating the working local copy, but how to print the modification in the command line, the way the svn update command works?

$es = New-Object 'System.Collections.Generic.Dictionary[string [SharpSvn.SvnUpdateResult]]
$result = New-Object -TypeName SharpSvn.SvnUpdateResult -ArgumentList $es, 0

$svnClient = New-Object SharpSvn.SvnClient
[boolean] $stat = $svnClient.Update([string]$localDir, [ref]$result)
if ($stat -eq "True") {
    Write-Host " ..Done" -ForegroundColor Green
    if ($result.HasRevision) {
        Write-Host -NoNewLine ' Revision: '
        Write-Host $result.Revision
    }

There is a piece of code which I found online, but it didn't helped.

SvnUpdateArgs ua = new SvnUpdateArgs();
ua.Notify += delegate(object sender, SvnNotifyEventArgs e)
        {
            Console.Write(e.Action);
            Console.WriteLine(e.FullPath);
        };
ua = New-Object SharpSvn.SvnUpdateArgs();
