Randomise a name

[youquijano]

have you seen my code?

try this

private void btnEnter_Click(object sender,EventArgs e) {
if(!string.IsNullOrEmpty(textName.Text.Trim())) {
listBox1.Items.Add(textName.Text);
textName.Clear();
textName.Focus();
}
}

private void btnRandomise_Click(object sender,EventArgs e) {
Random rnd = new Random();
List<string> randomised = new List<string>();
int cntr = 0;
while(cntr != listBox1.Items.Count) {
int pos = rnd.Next(1,listBox1.Items.Count + 1);
if(!listBox2.Items.Contains(listBox1.Items[pos - 1].ToString())
/*&& !randomised.Contains(listBox1.Text[pos-1].ToString())*/) {
listBox2.Items.Add(listBox1.Items[pos - 1]);
randomised.Add(listBox1.Items[pos - 1].ToString());
cntr++;
}
}
}

i think this is what you need ?
