Random Generator Names in a Drop Down Box

Question

I am trying to write a program that will randomly generate a list of names that are in a drop down box. Example: In one drop down box, I have 6 names, and when I press the Generate button, I want it to randomly pick one of those names in the box. I am not familiar with c# completely. I appreciate everyone's help in this for me.

What do you mean? Why would you have same names appear in you dropdownlist if you're the one populating it?

Thank you very much! It worked! Now here's another question, if I have the same names that appear in the drop down boxes, how can I set it up to not appear twice in a drop down box?

//I dragged 1 listbox, 1 textbox, and 1 button //I double clicked on my form for it to create a form1_load event private void Form1_Load(object sender, EventArgs e) { listBox1.Items.Add("Jan"); listBox1.Items.Add("Aimee"); listBox1.Items.Add("Cjo"); } //I double-clicked on the button for it to create a button1_click event private void button1_Click(object sender, EventArgs e) { Random randomizer = new Random(); // to be used in reading the items in the list box. in this scenario, listBox1.Items.Count is equal to 3. so the randomizer.next generates numbers from 0 up to 3-1, or simply put: 0 to 2. int randomIndex = randomizer.Next(0, listBox1.Items.Count); string randomName = listBox1.Items[randomIndex].ToString(); textBox1.Text = randomName; }
