C# wrap text inside a listbox

Question

I want to display a list of words in a listbox, wrapped them together. Below is an example what I want to do. I was able to add words to listbox with a comma and in one line. Can you please help me to wrap this text.

For comma separation I used, ListBox.Items.Add(string.Join(",", myList));

Expected output-

Below is my output

Answer 1

I do not think its possible to print multiple text lines per ListBox item with the standard ListBox . Try using a TextBox instead, with Multiline = true

  this.textBox1.Text = string.Join(",", UniqueWord(myList));
