How to generate a random 10 digit number in C#?

Question

I\'m using C# and I need to generate a random 10 digit number. So far, I\'ve only had luck finding examples indicating min maximum value. How would i go about generating a r

Answer 1

try (though not absolutely exact)

Random R = new Random();

return ((long)R.Next (0, 100000 ) * (long)R.Next (0, 100000 )).ToString ().PadLeft (10, '0');

Answer 2

I tried to write a fast one:

private int GetNDigitsRandomNumber(int digits)
{
    var min = 1;
    for (int i = 0; i < digits-1; i++)
    {
          min *= 10;
    }
    var max = min * 10;

    return _rnd.Next(min, max);
}

Answer 3

private void button1_Click(object sender, EventArgs e)
{
   Random rand = new Random();
   long randnum2 = (long)(rand.NextDouble() * 9000000000) + 1000000000;
   MessageBox.Show(randnum2.ToString());
}

Answer 4

To generate a random 10 digit number in C#

Random RndNum = new Random();   

int RnNum = RndNum.Next(1000000000,9999999999);

Answer 5

Use this to create random digits with any specified length

public string RandomDigits(int length)
{
    var random = new Random();
    string s = string.Empty;
    for (int i = 0; i < length; i++)
        s = String.Concat(s, random.Next(10).ToString());
    return s;
}

Answer 6

Random random = new Random();
string randomNumber = string.Join(string.Empty, Enumerable.Range(0, 10).Select(number => random.Next(0, 9).ToString()));
