How can I choose a random integer between to given integers?
For example, I'd like to pick a random integer between 1 and 3. E.g. 1, 2,
or 3
If I do
Dim oRandom As New Random(1)
Response.Write oRandom.Next(3)
will I get a different number between 1 and 3 every time, even if I'm always
using 1 as a seed?
Thanks!

For a given seed, you'll always get the same sequence of "random"
numbers. So, yes, if you always use the seed 1, the sequence of numbers
..Next will return will be the same.
If you want a more randomized experience, simply omit the seed. The
Random class will cause a seed obtained from the system clock to be
used, so it should produce different sequences of numbers each time.

Thanks Scott, but without the seed, is there a way to ensure the number is
between, for example, 1 and 3? Or will it grab a random number between 0 and
3?

The seed = 1 does not mean your random number starts with 1. If you want to
get an integer between 1 - 3 just use Next(int minValue, int maxValue)
ie:
Random random = new Random();
int result = random.Next(1, 3);

I cannot get the random number generator to work.
I tried seeding with Date.Now.Milliseconds, it still results in the same values.
What I have are arrays of values.
I get a random index value for each array so I can pull the data from them.

I needed a quick program called "random" that gives a random
positive integer from n1 to n2. For example, if I type
"random 38, 43", I want the program to print a random member
of the set {38, 39, 40, 41, 42, 43}.
Also, I read in my compiler's documentation the following:
To get a random number in the range 0..N, use rand()%(N+1).
Note that the low bits of the rand's return value are not
very random, so rand()%N for small values of N...

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
