Accepted answer
number in string..

private static string _numbers = "0123456789";
Random random = new Random();
private void DoWork()
{
StringBuilder builder = new StringBuilder(6);
string numberAsString = "";
int numberAsNumber = 0;
for (var i = 0; i < 6; i++)
{
builder.Append(_numbers[random.Next(0, _numbers.Length)]);
}
numberAsString = builder.ToString();
numberAsNumber = int.Parse(numberAsString);
}

in integer

Random generator = new Random();
int r = generator.Next(100000, 999999);
int r1 = generator.Next(100000, 1000000);
