I got a code for listview that can read a text file. but there is a problem with this code its in Add items to the list.

private void Form1_Load(System.Object sender, System.EventArgs e)
{
   ListView1.View = View.Details;
   ListView1.GridLines = true;
   ListView1.FullRowSelect = true;
   ListView1.HideSelection = false;
   ListView1.MultiSelect = false;
   ListView1.Columns.Add("IP", 90, HorizontalAlignment.Left);
   ListView1.Columns.Add("Port", 40, HorizontalAlignment.Left);
   ListView1.Columns.Add("Protocol", 80, HorizontalAlignment.Left);
   ListView1.Columns.Add("Type", 60, HorizontalAlignment.Left);
   ListView1.Columns.Add("Speed", 50, HorizontalAlignment.Left);
}

private void Button4_Click(System.Object sender, System.EventArgs e)
{
   OpenFileDialog1.ShowDialog();
   string filepath = OpenFileDialog1.FileName;
   System.IO.StreamReader inputstream = new System.IO.StreamReader(filepath);
   string[] newstr = new string[3];
   string IP = null;
   string Port = null;
   string Protocol = null;
   string Type = null;
   string Speed = null;

   //Read while there is mor characters to read
   while (inputstream.Peek() != -1) {
      //Split each line containing Account|Password into the array
      newstr = inputstream.ReadLine().Split("|");
      //Assigm the values to the variables
      IP = newstr[0];
      Port = newstr[1];
      Protocol = newstr[2];
      Type = newstr[3];
      Speed = newstr[4];

      //Add them to the list
      this.ListView1.Items.Add(IP);
      this.ListView1.Items.Item(ListView1.Items.Count - 1).SubItems.Add(Port);
      this.ListView1.Items.Item(ListView1.Items.Count - 1).SubItems.Add(Protocol);
      this.ListView1.Items.Item(ListView1.Items.Count - 1).SubItems.Add(Type);
      this.ListView1.Items.Item(ListView1.Items.Count - 1).SubItems.Add(Speed);
   }

   inputstream.Close();
}

private void Button3_Click(object sender, EventArgs e)
{
   foreach (ListViewItem Item in ListView1.Items) {
      ListView1.Items.Remove(Item);
   }
}
