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 … WebThe point in the sequence where a particular run of pseudo-random values begins is selected using an integer called the seed value. The seed is normally set from some arbitrary value like the system clock before the random number functions are used. This prevents the same run of values from occurring each time a game is played and thus …
