Equals(String, String) Method in C#

The Equals() method in C# is used to check whether two String objects have the same value or not.

Syntax

bool string.Equals(string s1, string s2)

Above, s1 and s2 are the strings to be compared.

Example

 Live Demo

using System;
public class Demo {
   public static void Main(string[] args) {
      string s1 = "Kevin";
      string s2 = "Tom";
      string s3 = s2;
      Console.WriteLine("String1 = "+s1);
      Console.WriteLine("String2 = "+s2);
      Console.WriteLine("Are both the strings equal? = "+s1.Equals(s2));
      Console.WriteLine("Are both the strings equal? = "+s2.Equals(s3));
   }
}

Output

String1 = Kevin
String2 = Tom
Are both the strings equal? = False
Are both the strings equal? = True

Example

 Live Demo

using System;
public class Demo {
   public static void Main(string[] args) {
      string s1 = "David";
      string s2 = "David";
      string s3 = s2;
      string s4 = "Tom";
      string s5 = s4;
      Console.WriteLine("String1 = "+s1);
      Console.WriteLine("String2 = "+s2);
      Console.WriteLine("String3 = "+s3);
      Console.WriteLine("String4 = "+s4);
      Console.WriteLine("String5 = "+s5);
      Console.WriteLine("Is s1 and s2 equal? = "+s1.Equals(s2));
      Console.WriteLine("Is s2 and s3 equal? = "+s2.Equals(s3));
      Console.WriteLine("Is s3 and s4 equal? = "+s3.Equals(s4));
      Console.WriteLine("Is s4 and s5 equal? = "+s4.Equals(s5));
   }
}

Output

String1 = David
String2 = David
String3 = David
String4 = Tom
String5 = Tom
Is s1 and s2 equal? = True
Is s2 and s3 equal? = True
Is s3 and s4 equal? = False
Is s4 and s5 equal? = True
