WebAug 10, 2024 · The Random Class. For a long time now, we’ve been able to use the Random class to generate “random” numbers. For example : var randomGenerator = new Random (); randomGenerator.Next (1, 1000000); This generates us a random number between 1 and 1 million. However, the Random in C# uses a “seed” value that then uses an algorithm to ... WebAug 11, 2024 · 1.

Example. The most useful method on RNGCryptoServiceProvider is the GetBytes method. You can enclose it in a using-statement. We fill a 4-byte array with GetBytes 10 times. Then We use BitConverter.ToInt32 to change those 4-byte arrays into integers. This yields random integers.
