Convert bool to int in C#

This post will discuss how to convert bool to int in C#. The boolean value true is represented by 1, and false by 0.

1. Using `Convert.ToInt32()` method

Unlike C++, C# doesn’t support implicit conversion from type bool to int. The Convert.ToInt32() converts the specified value to the equivalent 32-bit signed integer. It is overloaded for all data types, including Boolean, and returns the integer 1 if the specified value is true; otherwise, 0.

The following example converts the boolean value true to 1 and boolean value false to 0 using Convert.ToInt32().

using System;

public class Example

{

public static void Main()

{

bool b = true;

int i = Convert.ToInt32(b);

Console.WriteLine(i); // 1

b = false;

i = Convert.ToInt32(b);

Console.WriteLine(i); // 0

}

2. Using Custom method

We can also explicitly create an extension method to convert a boolean value to an integer. The following example provides an illustration.

using System;

public static class Extensions

{

public static int ToInt(this bool value)

{

return value ? 1 : 0;

}

public class Example

{

public static void Main()

{

bool b = true;

int i = b.ToInt();

Console.WriteLine(i); // 1

b = false;

i = b.ToInt();

Console.WriteLine(i); // 0

}
