.ToCharArray()

The .ToCharArray() method in C# converts a string into an array of characters, where each character in the string becomes an element in the resulting array. This allows for the manipulation or iteration of individual characters.

Syntax

char[] arrayName = stringName.ToCharArray();

• stringName: The string to be converted into a character array.
• arrayName: The resulting array containing individual characters from the string.

Optional Parameters

The .ToCharArray() method can also take optional parameters to convert a specific substring into a character array:

char[] substringArray = stringName.ToCharArray(startIndex, length);

• startIndex: The zero-based index where the substring starts.
• length: The number of characters to include in the resulting array, starting from startIndex.

Examples

Split into Individual Characters

Here’s an example of using .ToCharArray() to split a string into individual characters:

using System;

class Program
{
    static void Main()
    {
        string greeting = "Hello, World!";
        char[] charArray = greeting.ToCharArray();

        foreach (char c in charArray)
        {
            Console.WriteLine(c);
        }
    }
}

The output of the above code will be as follows:

H
e
l
l
o
,

W
o
r
l
d
!

Converting a Substring to a Character Array

using System;

class Program
{
    static void Main()
    {
        string phrase = "Convert this string!";
        char[] partialArray = phrase.ToCharArray(8, 4);

        foreach (char c in partialArray)
        {
            Console.WriteLine(c);
        }
    }
}

The output of the above code will be as follows:

t
h
i
s
