vb.net random number generator seed

 

 

 

 

The Random class is used to generate non-negative pseudo-random integers that are not truly random, but are for general purposes close enough. The sequence is calculated using an initial number (called the Seed) In earlier versions of .net, this seed number was the same every time an Random Number Generator.

Each time you create a new instance of Random you are resetting the random number generator. Since the default constructor uses Environment.TickCount as the seed you are often returning precisely the same sequence of pseudo-random numbers. To truncate a number in VB .NET, you can use the Floor method. It returns the largest whole number smaller than the orginal number.

Additionally, unlike Rnd, System.Random automatically seeds its random number generator with a random value derived from the current date and time. Home. Similar Sites. Vb.net Random Number Generator Seed.
