C#: byte

Handbook C# · Practical Guide

An unsigned 8-bit integer, from 0 to 255.

Simple example (Example.cs)

Save this example separately as Example.cs. Run it independently of the other examples on this page.

Example.cs:

// PROJECT-EXAMPLE
byte amount = 12;
System.Console.WriteLine(amount + 2);

Result:

14

Syntax

byte value = 12;

The type of the variable determines the range and rules of arithmetic. To check the overflow of integers, use checked; for text conversion — TryParse.

Example 1: simple form

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Threading.Tasks;
using System.IO;
using System.Runtime.InteropServices;
using System.Runtime.CompilerServices;

public static class Program
{
    public static async Task Main(string[] args)
    {
        byte first = 12;
        byte second = 2;
        Console.WriteLine(first + second);
    }
}

Example 2: another practical form

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading;
using System.Threading.Tasks;
using System.IO;
using System.Runtime.InteropServices;
using System.Runtime.CompilerServices;

public static class Program
{
    public static async Task Main(string[] args)
    {
        byte[] values = [12, 2, 3];
        foreach (byte value in values) Console.WriteLine(value);
        Console.WriteLine(byte.MaxValue);
    }
}
