Random double between given numbers

Question

I'm looking for some succinct, modern C# code to generate a random double number between 1.41421 and 3.14159. where the number should be [0-9]{1}.[0-9]{5} format.

I'm thinking some solution that utilizes Enumerable.Range somehow may make this more succinct.

Answer 1

You can easily define a method that returns a random number between two values:

private static readonly Random random = new Random();

private static double RandomNumberBetween(double minValue, double maxValue)
{
    var next = random.NextDouble();

    return minValue + (next * (maxValue - minValue));
}

You can then call this method with your desired values:

RandomNumberBetween(1.41421, 3.14159)

Answer 2

Use something like this.

Random random = new Random()
int r = random.Next(141421, 314160); //+1 as end is excluded.
Double result = (Double)r / 100000.00;
