如何通过C＃在数据集数据表中计算移动平均计算？

Question

Is there any way to do moving average calculations in Dataset Datatable. Is this the best option for calculating moving average calculations by using C sharp? what i am thinking is Datatable looks like excel, because of i am very familier with Excel and vba macros i think this is the best options. I am just beginer in C sharp i don't know other options, so anyone have any information about it, it will very helpful for me. And thanks in advance for your time.

Answer 1

Something as simple as this could do the trick.

static class Extensions
{
     public static IEnumerable<double> MovingAverage(this double[] numbers, int runs)
     {
         for (var i = 0; i < numbers.Length - runs + 1; i++)
             yield return Enumerable.Range(i, runs).Average(idx => numbers[idx]);
     }
}

Use case:

 foreach (var number in new[] {1d, 2d, 7d, 4d, 5}.MovingAverage(2))
     Console.WriteLine(number);
