Question

i have defined a method like this:

private String getRadndomNumber(int min, int max) {
    Random rnd = new Random((int) DateTime.Now.Ticks & 0x0000FFFF);
    return Convert.ToString(rnd.Next(min,max));
}

I am defining both seed and min,max interval , I wanted to know whether the SEED value is of any help here or not ?

tnx 🙂

Seed helps you generate a random number, it’s the base number used for their random algorithm. Using the same seed each time could end up with a predictable set of “random” numbers coming out in sequence.

From the MS documentation:

“If your application requires different random number sequences,
invoke this constructor repeatedly with different seed values. One way
to produce a unique seed value is to make it time-dependent. For
example, derive the seed value from the system clock. However, the
system clock might not have sufficient resolution to provide different
invocations of this constructor with a different seed value.”

The default constructor uses the system clock as seed but multiple instances created in the same tick could cause predictable numbers between the generators.
