Powershell-string to listview

我创建了一个c#应用程序，除其他外，它应该通过使用powershell代码将已安装的程序获取到远程计算机上。我可以运行代码，但它只将项目添加到单行中的单列，我不能在其中滚动。

你能告诉我如何将每个程序添加到新行，其中标题是:程序，供应商，版本?以下是ps1代码:

Invoke-Command -ComputerName $computername -ScriptBlock {
    $SWInstalled = get-wmiobject Win32_product | select @{Label="Program";Expression={$_.Name}}, version, vendor | Sort-Object Program
    $SWInstalled | ft
}

下面是相关的c#代码:

        private string RunScript(string scriptText)
        {
            // create Powershell runspace 
            Runspace runspace = RunspaceFactory.CreateRunspace();
            // open it 
            runspace.Open();
            runspace.SessionStateProxy.SetVariable("ComputerName", CompnameInput.Text);
            runspace.SessionStateProxy.SetVariable("user", UserNameInput.Text);
            // create a pipeline and feed it the script text 
            Pipeline pipeline = runspace.CreatePipeline();
            pipeline.Commands.AddScript(scriptText);
            // add an extra command to transform the script output objects into nicely formatted strings 
            // remove this line to get the actual objects that the script returns. For example, the script 
            // "Get-Process" returns a collection of System.Diagnostics.Process instances. 
            pipeline.Commands.Add("Out-String");
            // execute the script 
            Collection<PSObject> results = pipeline.Invoke();
            // close the runspace 
            runspace.Close();
            // convert the script result into a single string 
            StringBuilder stringBuilder = new StringBuilder();
            foreach (PSObject obj in results)
            {
                stringBuilder.AppendLine(obj.ToString());
            }
            // return the results of the script that has 
            // now been converted to text 
            return stringBuilder.ToString();
        }
        // helper method that takes your script path, loads up the script 
        // into a variable, and passes the variable to the RunScript method 
        // that will then execute the contents 
        private string LoadScript(string filename)
        {
            try
            {
                // Create an instance of StreamReader to read from our file. 
                // The using statement also closes the StreamReader. 
                using (StreamReader sr = new StreamReader(filename))
                {
                    // use a string builder to get all our lines from the file 
                    StringBuilder fileContents = new StringBuilder();
                    // string to hold the current line 
                    string curLine;
                    // loop through our file and read each line into our 
                    // stringbuilder as we go along 
                    while ((curLine = sr.ReadLine()) != null)
                    {
                        // read each line and MAKE SURE YOU ADD BACK THE 
                        // LINEFEED THAT IT THE ReadLine() METHOD STRIPS OFF 
                        fileContents.Append(curLine + "'n");
                    }
                    // call RunScript and pass in our file contents 
                    // converted to a string 
                    return fileContents.ToString();
                }
            }
            catch (Exception e)
            {
                // Let the user know what went wrong. 
                string errorText = "The file could not be read:";
                errorText += e.Message + "'n";
                return errorText;
            }

        private void GetSWButton_Click(object sender, RoutedEventArgs e)
        {
            SWList.Items.Clear();
            SWList.Items.Add((RunScript(LoadScript(@"C:'Get_Installed_Software.ps1"))));
        }
    }
}

还有，这里是XAML代码:

<ListView x:Name="SWList" Height="404" Margin="36,169,36,51" VerticalAlignment="Center" RenderTransformOrigin="0.5,0.5" ScrollViewer.HorizontalScrollBarVisibility="Disabled" BorderThickness="0" Visibility="Hidden" Grid.Row="2">
    <ListView.RenderTransform>
        <TransformGroup>
            <ScaleTransform/>
            <SkewTransform AngleX="-0.0"/>
            <RotateTransform/>
            <TranslateTransform X="0.346"/>
        </TransformGroup>
    </ListView.RenderTransform>
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Program" DisplayMemberBinding ="{Binding 'Program'}" Width="440"/>
            <GridViewColumn Header="Vendor" DisplayMemberBinding="{Binding 'Vendor'}" Width="281"/>
            <GridViewColumn Header="Version" DisplayMemberBinding ="{Binding 'Version'}" Width="150"/>
        </GridView>
    </ListView.View>
</ListView>

private Collection<PSObject> RunScript(string scriptText)
    {
        // create Powershell runspace 
        Runspace runspace = RunspaceFactory.CreateRunspace();
        // open it 
        runspace.Open();
        runspace.SessionStateProxy.SetVariable("ComputerName", CompnameInput.Text);
        runspace.SessionStateProxy.SetVariable("user", UserNameInput.Text);
        // create a pipeline and feed it the script text 
        Pipeline pipeline = runspace.CreatePipeline();
        pipeline.Commands.AddScript(scriptText);
        // add an extra command to transform the script output objects into nicely formatted strings 
        // remove this line to get the actual objects that the script returns. For example, the script 
        // "Get-Process" returns a collection of System.Diagnostics.Process instances. 
      //  pipeline.Commands.Add("Out-String");
        // execute the script 
        Collection<PSObject> results = pipeline.Invoke();
        // close the runspace 
        runspace.Close();
        return results;
