Solution 1

Try this Code:

C#

var chars = "0123456789";
 var random = new Random();
var result = new string(Enumerable.Repeat(chars, 2).Select(s => s[random.Next(s.Length)]).ToArray());

Change this Repeat(char,3) and var chars = "0123456789";

thanks what you gave can simply be achieved via using rand.next(1000, 9999)
but i want to use for loop to have the numbers generated many times like sey 10 times instead of generating only once

for (int i = 0; i < 10; i++)
{
int lbl = rand.Next(1000, 999);

LblNumber.Text = lbl.ToString();
}
but the code above only generate one i want the to be upto 10 at once like this
123
132
234
254 and so on
