Generate Random Number and String with C# | Visual Studio 2019
Pseudo-random numbers are chosen with equal probability from a finite set of numbers. The chosen numbers are not completely random because a mathematical algorithm is used to select them, but they are sufficiently random for practical purposes.
You can generate the same sequence of random numbers by providing the same seed value to the Random(Int32) constructor. The seed value provides a starting value for the pseudo-random number generation algorithm. The following example uses 100100 as an arbitrary seed value to instantiate the Random object, displays 20 random floating-point values, and persists the seed value. It then restores the seed value, instantiates a new random number generator, and displays the same 20 random floating-point values. Note that the example may produce different sequences of random numbers if run on different versions of the .NET Framework.
