basicly im making a simple program that genrates numbers for a game 1 - 10 but it cant generate same number 2s its to decide which player operates which control

int sd;

Random rnd =new Random();

sd= rnd.Next(10);

is simple code for random number how ever i did then think to put all 55 numbers in a list box and use index to genrat random index number every time get that value then remove it from the index how ever this didnt work as well as id hope so id like to know if any 1 knows another way or if they can think of a betta way of doing it thro list box

sorry full code

int sd;

int b; b = 0;

for (int x = 0; x < this.listBox1.Items.Count; x++)

{

b++;

this.listBox1.SetSelected(x, true);

}

Random rnd =new Random();

sd= rnd.Next(b);

b = b - 1;

string s = this.listBox1.GetItemText(sd).ToString() ;

MessageBox.Show(s);

listBox1.Items.Remove(sd.ToString());
