Different Ways to Convert Char Array to String in C#
  • Last Updated : 28 May, 2020

We have given a character array arr and the task is to convert char array to string str in C#

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

In order to do this task, we have the following methods:

Method 1: 

Using string() Method: The String class has several overloaded constructors which take an array of characters or bytes. Thus it can be used to create a new string from the character array.

Syntax:

string str = new string(character_array);

Example:



C#

filter_none

code

// C# program to convert the
// char array to string
using System;
using System.Text;
  
public class GFG{
      
    static string getString(char[] arr) 
    {
        // string() is a used to 
        // convert the char array
        // to string
        string s = new string(arr);
          
        return s;
    }
    
    static void Main(string[] args)
    {
        // given character array
        char[] arr = {'G', 'e', 'e', 'k'
        's', 'F', 'o', 'r', 'G', 'e',
        'e', 'k', 's'};
          
        // function calling
        string str = getString(arr);
          
        // printing output
        Console.WriteLine(str);
  
    }
}

Method 2: 

Using Join() Method: This method is used to concatenates the members of a collection or the elements of the specified array, using the specified separator between each member or element. Thus it can be used to create a new string from the character array.

Syntax:

string str = string.Join("", character_array);

Example:

C#

filter_none

        // String.Join() is a used to 
        // convert the char array
        // to string
        string s = string.Join("", arr);
          
        return s;
    }
    
    static void Main(string[] args)
    {
        // given character array
        char[] arr = {'G', 'e', 'e', 'k'
        's', 'F', 'o', 'r', 'G', 'e',
        'e', 'k', 's'};
          
        // function calling
        string str = getString(arr);
          
        // printing output
        Console.WriteLine(str);
  
    }
}

Method 3: 

Using Concat() Method: This method is used to concatenate one or more instances of String or the String representations of the values of one or more instances of Object. Thus it can be used to create a new string from the character array.

Syntax:

string str = string.Concat(character_array);

Example:

C#

filter_none

        // convert the char array
        // to string
        string s = string.Concat(arr);
          
        return s;
    }
    
    static void Main(string[] args)
    {
        // given character array
        char[] arr = {'G', 'e', 'e', 'k'
        's', 'F', 'o', 'r', 'G', 'e',
        'e', 'k', 's'};
          
        // function calling
        string str = getString(arr);
          
        // printing output
        Console.WriteLine(str);
  
    }
