An Aggregate function takes more than two arguments and works on the requirement. there are many aggregate functions in LINQ

SOME function of LINQ

  1. SUM()    return the sum of a collection
  2. MIN()    return the minimum of collection
  3. MAX()     returns the maximum collection
  4. COUNT()    return the length of the collection
  5. Average()    return is the average of a collection
  6. Aggregate()   returns the value as needed from a collection

Example

using System;
using System.Linq;
using System.Collections.Generic;

class MyProgram
{ 
 static void Main(string[ ] args)
    { 

  int[] intAry = {45,78,5,896,4,5,8,65,99,66,55,88,5,558,56,55,45,23};
  var Sum = intAry.Where(x => x%2 == 0).Sum();
  Console.WriteLine('Sum of array : ' + Sum);

  var Min = intAry.Min();
  Console.WriteLine('Min of array : ' + Min);

  var Max = intAry.Max();
  Console.WriteLine('Max of array : ' + Max);

  var Count = intAry.Count();
  Console.WriteLine('Length of array : ' + Count);

  var Avg = intAry.Average();
  Console.WriteLine('Average of array : ' + Avg);

  var Aggregate = intAry.Aggregate((a,b) => a+b);
  Console.WriteLine('Aggregate function of array : ' + Aggregate);

    } 
}

Output

Sum of array : 1754

Min of array : 4

Max of array : 896

Length of array : 18

Average of array : 119.77777777777777

Aggregate function of array : 2156
