Overview

We can use the Convert.ToInt32(byte) method to convert a byte value to its equivalent 32-bit signed integer.

A byte is in the range of 0 to 255. An Int32 is in the range of -2,147,483,648 to 2,147,483,647.

Syntax

Convert.ToInt32(byteValue)
Syntax for converting a Byte to Int32 in C# using Convert.ToInt32(byte)

Parameters

  • byteValue: This is the byte value we want to convert to a 32-bit signed integer.

Return value

It returns an equivalent 32-bit signed integer of the specified byte value byteValue.

Code example

Let's look at the example below:

using System;
class HelloWorld
{
    static void Main()
    {
      // create some byte values
      byte byte1 = 20;
      byte byte2 = 255; // limit of a byte value
      byte byte3 = 45; 
      byte byte4 = 0;

      // print the data types of the bytes created
      Console.WriteLine(byte1.GetType());
      Console.WriteLine(byte2.GetType());
      Console.WriteLine(byte3.GetType());
      Console.WriteLine(byte4.GetType());

      // convert the bytes to Int32 and print results
      Console.WriteLine(Convert.ToInt32(byte1).GetType());
      Console.WriteLine(Convert.ToInt32(byte2).GetType());
      Console.WriteLine(Convert.ToInt32(byte3).GetType());
      Console.WriteLine(Convert.ToInt32(byte4).GetType());
    }
}
Convert a byte to Int32 in C#

Code explanation

  • Lines 7 to 10: We create some byte values.
  • Lines 13 to 16: We use the GetType() method to get the data type of byte values we created.
  • Lines 19 to 22: We use Convert.ToInt32() to convert the created byte values to Int32 values and print the type of data.
