I am writing a random question generator. I would like to pick one question from each section.
Random class with DateTime.Now.Milliseconds as seed value generates random numbers, if the range is greater than 2(0,2/2+). But, If I give a min of 0 and a max of 1 in the range, it always returns me 0.
Am I using it wrongly.
Please suggest if there are any other alternatives.
Thanks, Mahesh

Random. Next generates a random number whose value ranges from 0 to less than Int32. MaxValue. To generate a random number whose value ranges from 0 to some other positive number, use the Random.
Examples to Implement C# random Then the main method is called within which an instance of the Random class is created to be able to make use of the Next() method. Then the Next() method is called to generate a random integer value between −2,147,483,648 and +2,147,483,648 and stored in an integer variable.
Seed Int32. A number used to calculate a starting value for the pseudo-random number sequence. If a negative number is specified, the absolute value of the number is used.
You're calling Random.Next, which returns a random integer more than or equal to the first parameter and less than, but not equal to, the second.
Specifically, you're asking for an integer in the range [0, 1), which can only be zero.
If you're looking for an integer that is either 0 or 1, you need to call Random.Next(0, 2).
If you're looking for a real number between 0 and 1, you need to call Random.NextDouble.
