Step 1: Click cs to Cut-n-paste code into clsConvertToObject.cs
using System; public class clsConvertToObject { public void Main() { //**************************************************************************************** // Purpose: Converts any valid expression into Object data type // // Syntax: (object)(expression) // // Parameter1: expression - any valid expression // // Result: object - returns input as an object // // Quick Example: (object)("Ideal") // Returns Ideal // //**************************************************************************************** // This example is from http://idealprogrammer.com Console.WriteLine("Example #1: (object)(expression)"); object Object1 = (object)("Ideal"); Console.WriteLine(Object1); // Returns Ideal //write blank line to make output easier to read Console.WriteLine(); Console.WriteLine("Example #2: (object)(expression)"); object Object2 = (object)-3.4; Console.WriteLine(Object2); // Returns -3.4 //write blank line to make output easier to read Console.WriteLine(); Console.WriteLine("Example #3: (object)(expression)"); object Object3 = (object)5.5; Console.WriteLine((object)Object3); // Returns 5.5 //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 myclsConvertToObject As New clsConvertToObject myclsConvertToObject.Main() End Sub End Module |
Prerequistes:
- Install C-Sharp (Express or Standard Edition)
- Install SQL Server Express
- Download Northwind and pubs Database
- 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
