Try the following to concatenate the ListBox items into a single string: int count = ListBox1.Items.Count; string[] items = new string[count]; for(int i = 0; i { items[i] = ListBox1.Items[i].Text; } string text = String.Join(  items); // assuming separator is a space If in the Properties Box you change the SelectionMode for the ListBox to Multiple then it should allow you to select all the items at once.
