In this article, we would like to show you how to add character to string in C#.

Quick solution:

xxxxxxxxxx
 
string text = "ABC";
char character = 'x';
string result = text + character;
​
Console.WriteLine(result); // ABCDx

or:

xxxxxxxxxx
 
string text = "ABCD";
char character = 'x';
int index = 1;
​
string result = text.Insert(index, character.ToString());
​
Console.WriteLine(result); // AxBCD

1. Practical example using `+` operator

Edit

In this example, we add a character at the end of the text string using + operator.

xxxxxxxxxx
 
using System;
​
public class TestClass
{
    public static void Main()
    {
        string text = "ABC";
        char character = 'x';
        string result = text + character;
​
        Console.WriteLine(result);
    }
}

Output:

xxxxxxxxxx
 
ABCDx

2. Using `String.Insert()` method

Edit

In this example, we use Insert() method to add a character to the string at specific position (index).

xxxxxxxxxx
 
using System;
​
public class TestClass
{
    public static void Main()
    {
        string text = "ABCD";
        char character = 'x';
        int index = 1;
​
        string result = text.Insert(index, character.ToString());
​
        Console.WriteLine(result);
    }
}
