Convert String to Character Array in C#

  • Last Updated : 26 May, 2020

Given a string, the task is to convert this string into a character array in C#.

Examples:

Input:  string 
Output:  [s, t, r, i, n, g]
  
Input:  GeeksForGeeks
Output:  [G, e, e, k, s, F, o, r, G, e, e, k, s]  

Method 1: Naive Approach

Step 1: Get the string.

Step 2: Create a character array of the same length as of string.



Step 3: Traverse over the string to copy character at the i’th index of string to i’th index in the array.

Step 4: Return or perform the operation on the character array.

Below is the implementation of the above approach:

C#




// C# program to Convert a string 
// to a Character array 
// using Naive Approach 
    
using System;
  
public class GFG{
    
    static public void Main ()
    
        string str = "GeeksForGeeks"
    
        // Creating array of string length 
        char[] ch = new char[str.Length]; 
    
        // Copy character by character into array 
        for (int i = 0; i < str.Length; i++) { 
            ch[i] = str[i]; 
        
    
        // Printing content of array 
        foreach  (char c in ch) { 
            Console.WriteLine(c); 
        
    
}

Output:

G
e
e
k
s
F
o
r
G
e
e
k
s

Method 2: Using toCharArray() Method

Step 1: Get the string.

Step 2: Create a character array of same length as of string.

Step 3: Store the array return by toCharArray() method.

Step 4: Return or perform operation on character array.

C#




// C# program to Convert a string 
// to a Character array 
// using ToCharArray method 
    
using System;
  
public class GFG{
    
    static public void Main ()
    
        string str = "GeeksForGeeks"
    
        // Creating array of string length 
        // Copy character by character into array 
        char[] ch = str.ToCharArray();
    
        // Printing content of array 
        foreach  (char c in ch) { 
            Console.WriteLine(c); 
        
    
}

Output:

G
e
e
k
s
F
o
r
G
e
e
k
s
