Calculate with X number of variables-CodePudding

I am wondering how I could make a calculation (in this case, calculating the average) with a variable number of variables / fields in C#? I could write an if case for each number of variables but I bet there is a better way for it, right? The bad way would like this:

if (numberOfFields == 4)
   (field1   field2   field3   field4) / 4;
if (numberOfFields == 5)
   (field1   field2   field3   field4   field5) / 5;
.
.
.

Greetings!

Organize your variables (field1, field2...) into a collection, say, array (you can well use List<T> and many other collections):

 //TODO: put the right type here
 double[] array = new double[] {
   field1,
   field2,
   field3,
   field4,
   field5,
   ... 
 };

Then query with a help of LInq:

 using System.Linq;

 ...

 var average = array
   .Take(numberOfFields)
   .Average();
