Saving Powershell command output to listbox

问题

Trying to write some GUI program using c#.

I need to execute some Powershell commands (Like Get-ContentFilterPhrase) and add their output to list box. Everything I was able to get right now is just a (Collection) in the first line of my listbox.

Could anyone describe how to do that right, please.

Here's one of my attempts:

var rulelist = new List<string>();
        var rsConfig = RunspaceConfiguration.Create();
        using (var myRunSpace = RunspaceFactory.CreateRunspace(rsConfig))
        {
            PSSnapInException snapInException = null;
            var info = rsConfig.AddPSSnapIn("Microsoft.Exchange.Management.PowerShell.E2010", out snapInException);

            myRunSpace.Open();

            using (var ps = PowerShell.Create())
            {
                ps.AddScript("Get-ContentFilterPhrase | Where-Object {$_.Influence -Match 'BadWord'}| Format-Table -Property Phrase");
                var results = ps.Invoke();
                foreach (var result in results)
                {
                    rulelist.Add(result.ToString());
                }
            }
            listBox1.Items.Add(rulelist);
        }
