I want it to do this

First listbox (or textbox): red
Second listbox (no textbox): 1234
minecraft
batman
password123

then the outcome

red:1234
red:minecraft
red:batman
red:password123

I figured out to combine two listboxes that have the same amount of items in item in it, but I need it to be able to combine 1 into several like above. Thanks.

I've dealt with this exact question before. Give me a minute so I can find my answer.

Edit- found it:

Code

listBox1.Items.AddRange(input.SelectMany(u => input, (u, p) => string.Join(':', u, p)).ToArray())

Assuming input is a collection.

Something like this?

Code

foreach(string s in listBox1.Items)
{
    listBox2.Items.Add(textBox1.Text + ":" + s);
}
