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:
- Install C-Sharp (Express or Standard Edition)

- Attach Northwind Database to Databases in Sql Express
- 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
