C# Load .txt file and show in listview

so what I'm trying to do is load a .txt file and once the .txt file is loaded it will show the contents from the .txt file in a listView.

Here is my load code.

        List<String> proxies = new List<string>();
    private void loadProxiesToolStripMenuItem_Click(object sender, EventArgs e)
    {
        loadProxies();
    }

    private void loadProxies()
    {
        this.Invoke(new MethodInvoker(delegate
        {
            OpenFileDialog ofd = new OpenFileDialog();
            ofd.Filter = "TXT files|*.txt";
            ofd.Title = "Load Proxies";
            var dialogResult = ofd.ShowDialog();
            if (dialogResult == DialogResult.OK)
            {
                proxies = new List<string>();
                Parallel.ForEach(System.IO.File.ReadLines(ofd.FileName), (line, _, lineNumber) =>
                {
                    if (line.Contains(":"))
                    {
                        //loadedCombo.Add(line);
                        proxies.Add(line);
                    }
                    else
                    {
                        //MessageBox.Show("Hmm, thats not a combolist - please try again");
                    }
                });
            }

            txt_proxies.Text = "Proxies Loaded: " + proxies.Count.ToString();

        }));
    }

and I'm wanting it to show in the listView which is named "proxyView".

So what I'm trying to say it, I can get the .txt to load and it changes the count but it's not adding the contents from the .txt file into the listview.

Thanks much appreciated.

To add an item to a ListView you can use yourListView.Items.Add(text)

For example: 

private void loadProxies()
{ 
    OpenFileDialog ofd = new OpenFileDialog();
    ofd.Filter = "TXT files|*.txt";
    ofd.Title = "Load Proxies";
    var dialogResult = ofd.ShowDialog();
    if (dialogResult == DialogResult.OK)
    {
        foreach (var line in System.IO.File.ReadLines(ofd.FileName))
        {
            if (line.Contains(":"))
                proxyView.Items.Add(line);
        }
    }
}
