C-Sharp ConvertToByte Example – Code Sample Syntax

Purpose: – Illustrates using .

Purpose:
Converts 0 to 255 unsigned (rounded) into byte data type

Syntax:
Convert.ToByte(numeric expression)

Parameters Description
numeric expression 0 to 255

Result Data Type Description
Byte 0 to 255 unsigned and parameter1 is rounded

Quick Example
Convert.ToByte(255) // Returns 255

Step 1: Click cs to Cut-n-paste code into clsConvertToByte.cs

using System;
 
public class clsConvertToByte
{
 
    public void Main()
    {
 
 
        //****************************************************************************************
        // Purpose: Converts 0 to 255 unsigned (rounded) into byte data type
        //
        // Syntax: 	Convert.ToByte(numeric expression)
        //
        // Parameter1: numeric expression - 0 to 255
        //
        // Result: Byte - 0 to 255 unsigned and parameter1 is rounded
        //
        // Quick Example: Convert.ToByte(255) // Returns 255
        //
        //****************************************************************************************
        // This example is from http://idealprogrammer.com
 
        Console.WriteLine("Example #1: 	Convert.ToByte(numeric expression)");
 
 
        Console.WriteLine(Convert.ToByte(255)); // Returns 255
 
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
        Console.WriteLine("Example #2: 	Convert.ToByte(numeric expression)");
 
 
        Console.WriteLine(Convert.ToByte(1.5)); // Returns 2
 
        //Prevent console from closing before you press enter
        Console.ReadLine();
 
    }
 
}

Step 2: Click cs to Cut-n-paste code into Module1.cs

Module Module1
 
    Sub Main()
 
 
        Dim myclsConvertToByte As New clsConvertToByte
        myclsConvertToByte.Main()
 
 
 
    End Sub
 
End Module

Prerequistes:

  1. Install C-Sharp (Express or Standard Edition)
  2. Install SQL Server Express
  3. Download Northwind and pubs Database
  4. Attach Northwind Database to Databases in Sql Express
  5. Attach pubs Database to Databases in Sql Express

Notes:

  • Console Application is used to simplify things, but Windows Forms or Web Forms could also be used
  • You can build a library of syntax examples by using same project over and over and just commenting out what you do not want to execute in Module1.cs
