c# how to random number code example

Example 1: c# random number

int random_number = new Random().Next(1, 10) // Generates a number between 1 to 10

Example 2: c# random

byte[] bytes1 = new byte[100];
byte[] bytes2 = new byte[100];
Random rnd1 = new Random();
Random rnd2 = new Random();

rnd1.NextBytes(bytes1);
rnd2.NextBytes(bytes2);

Console.WriteLine("First Series:");
for (int ctr = bytes1.GetLowerBound(0);
     ctr <= bytes1.GetUpperBound(0);
     ctr++) {
   Console.Write("{0, 5}", bytes1[ctr]);
   if ((ctr + 1) % 10 == 0) Console.WriteLine();
}

Console.WriteLine();

Console.WriteLine("Second Series:");
for (int ctr = bytes2.GetLowerBound(0);
     ctr <= bytes2.GetUpperBound(0);
     ctr++) {
   Console.Write("{0, 5}", bytes2[ctr]);
   if ((ctr + 1) % 10 == 0) Console.WriteLine();
}

// The example displays output like the following:
//       First Series:
