C# String - Clone() Method

---

---

The C# String Clone() method is used to shallow copy of the string object. However, It's important to note that the clone method does not create a new string. It simply creates another view of the same data.

A shallow copy is a new object that shares the same instance variable as an existing object.

Syntax

Following is the syntax of the C# string Clone() method −

 public object Clone(); 

Parameters

This method does not accept any parameters −

Return value

This method returns instance of String.

Example 1

This is the basic example of the string Clone() method. We can use this method to create another view of the same data.

 using System; class Program { static void Main() { string original_string = "Hello, TutorialsPoint !"; object cloned_string = original_string.Clone(); Console.WriteLine($"Original: {original_string}"); Console.WriteLine($"Cloned: {cloned_string}"); Console.WriteLine($"Are both references equal? {ReferenceEquals(original_string, cloned_string)}"); } } 

Output

Following is the output −

 Original: Hello, TutorialsPoint ! Cloned: Hello, TutorialsPoint ! Are both references equal? True 

Example 2: Modify The String

Let us see another example of the Clone() method. Here, we modify the original string after cloning −

 using System; class Program { static void Main() { string original_str = "Learning C# in tutorialspoint is fun"; object cloned_str = original_str.Clone(); Console.WriteLine("Original String: " + original_str); Console.WriteLine("Cloned String: " + cloned_str); // Modify the original string original_str = "I love tutorialspoint"; Console.WriteLine("\nAfter modifying the original string:"); Console.WriteLine("Original String: " + original_str); Console.WriteLine("Cloned String: " + cloned_str); } } 

Output

Following is the output −

 Original String: Learning C# in tutorialspoint is fun Cloned String: Learning C# in tutorialspoint is fun After modifying the original string: Original String: I love tutorialspoint Cloned String: Learning C# in tutorialspoint is fun 

Example 3: Modify The Cloned String

Here, in this example we modified the cloned string −

 using System; class Program { static void Main() { string original = "Hii, TutorialsPoint!"; object cloned = original.Clone(); Console.WriteLine("Original String: " + original); Console.WriteLine("Cloned String: " + cloned); string modified_cloned = ((string)cloned).ToUpper(); Console.WriteLine("\nAre the references equal? " + ReferenceEquals(original, cloned)); Console.WriteLine("\nAfter modifying the cloned string:"); Console.WriteLine("Modified Cloned" + modified_cloned); } } 

Output

Following is the output −

 Original String: Hii, TutorialsPoint! Cloned String: Hii, TutorialsPoint! Are the references equal? True After modifying the cloned string: Modified ClonedHII, TUTORIALSPOINT!
