Add multiple items from ListBox to TextBox

If you know how to process multiple lines out of a list box, simply append the values together either into a string, then assign the value of the string to the text box, or directly into the text box.

Well, my solution for that would be :

consider we have a listbox on form, with its 'SelectionMode' property set to value 'MultiSimple', and a textbox which 'Multiline' property is true, and 'WordWrap' property is false. and of course a button to add items from listbox to textbox.

my code in the 'button1_Click' event would be :

private void button1_Click(object sender, EventArgs e)
{
int count = listBox1.SelectedItems.Count;

foreach (object item in listBox1.SelectedItems)
{
textBox1.Text += item.ToString();

if (listBox1.SelectedItems[count - 1] != item)
textBox1.Text += ", \r\n";
}
}

So, each selected item in listbox will be added ( as an string via ToString() function) to textbox's text, and if it isnt the last selected item, a comma and a new line will be added.
