C# tips and tricks 30 - Difference between Equals() method and == comparison operator in c#

What is “==“ ? The == is a comparison operator. The == Operator compares the reference identity. You can compare any primitive type such as int, char, float and Booleans. The == operator returns a boolean value. When used with objects, the == operator compares the two object references and determines whether they refer to the same instance. What is Equals() ? The Equals() method compares only the contents. Equals() is a method available in the String class that is used to compare two strings and determine whether they are equal. The Equals() returns a boolean value. Code sample : using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Threading.Tasks; namespace EqualentDemo { class Program { static void Main(string[] args) { int i = 10; int y = 10; Console.WriteLine(i==y); Console.WriteLine(i.Equals(y)+"
"); string a = "Ankpro"; string b = "Ankpro"; Console.WriteLine(a == b); Console.WriteLine(a.Equals(b)+"
"); Student std = new Student(); std.Name = "Ankpro"; Student std1 = new Student(); std.Name = "Ankpro"; Console.WriteLine(std == std1); Console.WriteLine(std.Equals(std1)+"
"); object str = new string(new char[] { 'A', 'N', 'K', 'P', 'R', 'O' }); object str1 = new string(new char[] { 'A', 'N', 'K', 'P', 'R', 'O' }); Console.WriteLine(str == str1); Console.WriteLine(str.Equals(str1)+"
"); int x = 10; byte z = 10; Console.WriteLine(z == x); Console.WriteLine(z.Equals(x) + "
"); } class Student { public string Name { get; set; } } } }
