Given a list, and we have to count its total number of elements using List.Count property.
C# List
A list is used to represent the list of the objects, it is represented as List<T>, where T is the type of the list objects/elements.
A list is a class which comes under System.Collections.Generic package, so we have to include it first.
List.Count property
Count is a property of List class; it returns the total number of elements of a List.
Syntax:
List_name.Count;
Here, List_name is the name of input/source list whose elements to be counted.
Example:
Input:
//an integer list
List<int> int_list = new List<int> { 10, 20, 30, 40, 50, 60, 70 };
//a string list
List<string> str_list = new List<string>{
"Manju", "Amit", "Abhi", "Radib", "Prem"
};
Function call:
int_list.Count;
str_list.Count;
Output:
7
5
C# program to count the total number of elements of a List
using System;
using System.Text;
using System.Collections.Generic;
namespace Test
{
class Program
{
static void Main(string[] args)
{
//an integer list
List<int> int_list = new List<int> { 10, 20, 30, 40, 50, 60, 70 };
//a string list
List<string> str_list = new List<string>{
"Manju", "Amit", "Abhi", "Radib", "Prem"
};
//printing total number of elements
Console.WriteLine("Total elements in int_list is: " + int_list.Count);
Console.WriteLine("Total elements in str_list is: " + str_list.Count);
//hit ENTER to exit
Console.ReadLine();
}
}
}
Output
Total elements in int_list is: 7
Total elements in str_list is: 5
