Convert int to a char in C#

This post will discuss how to convert an int to a char in C#.

1. Explicit conversion (casts)

C# doesn’t support implicit conversion from type ‘int’ to ‘char’ since the conversion is type-unsafe and risks potential data loss. However, we can do an explicit conversion using the cast operator (). A cast informs the compiler that the conversion is intentional.

The following program casts the value of an integer to a Char value.

using System;

public class Example

{

public static void Main()

{

int val = 65;

char ch = (char)val;

Console.WriteLine("{0} converts to '{1}'", val, ch);

}

Output: 65 converts to 'A'

2. Using `Convert.ToChar()` method

We can use the Convert.ToChar() method to convert an integer to its equivalent Unicode character. The following example converts the value of an integer to a char value. The program throws an OverflowException if it is outside the range of the char data type (0-65535).

using System;

public class Example

{

public static void Main()

{

int val = 65;

try {

char ch = Convert.ToChar(val);

Console.WriteLine("{0} converts to '{1}'", val, ch);

}

catch (OverflowException) {

Console.WriteLine("{0} is outside the range of the char datatype", val);

}

Output: 65 converts to 'A'

3. Using `Char.ConvertFromUtf32()` method

We can use the Char.ConvertFromUtf32() method to convert the specified Unicode code point into a UTF-16 encoded string.

using System;

public class Example

{

public static void Main()

{

int val = 65;

char ch = Char.ConvertFromUtf32(val)[0];

Console.WriteLine("{0} converts to '{1}'", val, ch);

}

Output: 65 converts to 'A'
