There are times when you want to declare a variable and assign a value to it even without having to figure out what the data type of the variable is .

In C# , the var keyword provides the type inference feature where the compiler decides what type the local variable is .

Below is a sample code snippet demonstrating the Implicit Type Inference in C#.

Implicit Type Inference in C#

using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Linq;
using System.Net;
namespace AbundantCode
    internal class Program
        // Implicit Type Inference in C#
        private static void Main(string[] args)
            var WelcomeMessage = " Welcome to";
            var Year = 2013;
            Console.WriteLine(WelcomeMessage + Year);


Below are some of the points related to the Implicit Type Inference in C#

– The variables returned are still strongly typed

– Cannot initialize the Implicit Type Inference variable to null.
