Convert List of Chars to a String in C#

This post will discuss how to convert a List of Chars to a String in C#.

1. Using `String.Join()` Method

The shortest and most idiomatic way to append characters of a list to a single string separated by a delimiter is using the String.Join method. The following code example demonstrates the usage of the String.Join method for concatenating characters of a list with a comma as a separator between each character.

using System;

using System.Collections.Generic;

public class Example

{

public static void Main()

{

List<char> chars = new List<char> { 'A', 'B', 'C' };

string s = string.Join(",", chars);

Console.WriteLine(s); // A,B,C

}

2. Using String Class Constructor

Another option for converting the list of characters to a string is to use the String constructor, which can accept a list of characters and initialize a new instance of the String object with the corresponding characters, without any delimiter. The following code example demonstrates this.

using System;

using System.Collections.Generic;

public class Example

{

public static void Main()

{

List<char> chars = new List<char> { 'A', 'B', 'C' };

string s = new string(chars.ToArray());

Console.WriteLine(s); // A,B,C

}

3. Using `String.Concat()` Method

Finally, you can also use the convenience method String.Concat() to concatenate the characters of a list separated by an empty string, as demonstrated below:

using System;

using System.Collections.Generic;

public class Example

{

public static void Main()

{

List<char> chars = new List<char> { 'A', 'B', 'C' };

string s = string.Concat(chars);

Console.WriteLine(s); // A,B,C

}
