Hi everyone.
I have two textBoxes on the form and one listView.
I want to add items from textBox1.Text to Column1 in listView, and items from textBox2.Text to Column2 in listViev1.
I tried the code below but it's not good enough.

Picture 1 is my result.
Picture 2 is as I would like it to be.
How to do it. Thank you.

       {
           try
           {
               string[] line = textBox2.Lines;
               var Column2 = line.ToString();
               foreach (var Column1 in textBox1.Lines)
                   if (!listView1.Items.ContainsKey(Column1))
                   {
                      listView1.Items.Add(new ListViewItem(new string[] { Column1, Column2 }));
                   }
           }
           catch
           {

           }
       }

This will give you the results you are looking for.

The issue was that you were not specifying which item in line you wanted to display.

C#

try
{
    int counter = 0; // Counter to increment to next item in lastNames
    string[] lastNames; 
    lastNames = textBox2.Lines; // Fills a string array with all the last names in textBox2

    foreach (var Column1 in textBox1.Lines)
    {
        // Selects the corresponding last name at the same index as first name. 
        // This assumes first and last names are in the correct order.
        var Column2 = lastNames[counter]; 

        if (!listView1.Items.ContainsKey(Column1))
        {
            listView1.Items.Add(new ListViewItem(new string[] { Column1, Column2 }));
        }

        counter++; // Increments the counter to the next item in lastNames
    }
}
catch
{

}
