 private void button1_Click(object sender, EventArgs e)

  {

   if (textBox1.Text == "")

   {

    MessageBox.Show(" Added content cannot be empty ");

    textBox1.Focus(); // Get the focus 

 

   }

   else

   {

    if (listView1.Items.Count > 0) // Determine whether there are items in the list box 

    {

     // Loop to compare whether there are duplicates, and abandon adding if there are duplicates 

     for (int i = 0; i < listView1.Items.Count; i++)

     {

      if (string.Compare(listView1.Items[i].Text.ToString(), textBox1.Text) == 0)

      {

       MessageBox.Show(" Items are duplicate and cannot be added! ");

       textBox1.Text = ""; // Empty the text box 

       textBox1.Focus();

       return;

      }

     }

     listView1.Items.Add(textBox1.Text.ToString());

     textBox1.Text = "";

    }

    else

    {

     listView1.Items.Add(textBox1.Text.ToString()); // Add data from a text box to a list box 

     textBox1.Text = "";

    }

 

   }

  }
