String literals vs. string objects in C#

String literals

String literals or constants are enclosed in double quotes "" or @"". Strings contain characters similar to character literals: plain characters, escape sequences, and universal characters.

The following are some examples of string literals -

Hello, World"
"Welcome, \

The following are examples 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 a string object using one of the following methods -

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

Here's how to 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() ;
      }
   }
}
