String Literal Vs String Object in C#

CsharpProgrammingServer Side Programming

String Literals

String literals or constants are enclosed in double quotes "" or with @"". A string contains characters that are similar to character literals: plain characters, escape sequences, and universal characters.

Here are some examples of String Literals −

Hello, World"
"Welcome, \

The following is an example showing the usage of string literals −

Example

using System;

namespace Demo {

   class Program {

      static void Main(string[] args) {

         // string
         string str1 ="Hello, World";
         Console.WriteLine(str1);

         // Multi-line string
         string str2 = @"Welcome,
         Hope you are doing great!";

         Console.WriteLine(str2);
      }
   }
}

String Object

Create string object using one of the following methods −

  • By assigning a string literal to a String variable
  • By using a String class constructor
  • By using the string concatenation operator (+)
  • By retrieving a property or calling a method that returns a string
  • By calling a formatting method to convert a value or an object to its string representation

The following is how you can create a string object and compare two strings −

Example

using System;

namespace Demo {

   class Program {

      static void Main(string[] args) {
         string str1 = "John";
         string str2 = "Andy";

         if (String.Compare(str1, str2) == 0) {
            Console.WriteLine(str1 + " and " + str2 + " are equal strings.");
         } else {
            Console.WriteLine(str1 + " and " + str2 + " are not equal strings.");
         }
         Console.ReadKey() ;
      }
   }
}
