C# program to multiply all numbers in the list

Firstly, set the list −

List<int> myList = new List<int> () {
   5,
   10,
   7
};

Now, set the value of a variable to 1 that would help us in multiplying −

int prod = 1;

Loop through and get the product −

foreach(int i in myList) {
   prod = prod*i;
}

The following is the code −

Example

 Live Demo

using System;
using System.Collections.Generic;

public class Program {
   public static void Main() {
      List<int> myList = new List<int>() {
         5,
         10,
         7
      };
      Console.WriteLine("List: ");
      foreach(int i in myList) {
         Console.WriteLine(i);
      }
      int prod = 1;
      foreach(int i in myList) {
         prod = prod*i;
      }
      Console.WriteLine("Product: {0}",prod);
   }
}

Output

List:
5
10
7
Product: 350
