Step 1: Click cs to Cut-n-paste code into clsConvertToDateTime.cs
using System; public class clsConvertToDateTime { public void Main() { //**************************************************************************************** // Purpose: Converts any valid date and time into date data type // // Syntax: Convert.ToDateTime(expression) // // Parameter1: expression - any valid representation of date and time // // Result: date - returns date // // Quick Example: Convert.ToDateTime("September 12, 2011") // Returns 9/12/2011 12:00:00 AM // //**************************************************************************************** // This example is from http://idealprogrammer.com Console.WriteLine("Example #1: Convert.ToDateTime(expression)"); DateTime date1 = Convert.ToDateTime("September 12, 2011"); Console.WriteLine(date1); // Returns 9/12/2011 12:00:00 AM //write blank line to make output easier to read Console.WriteLine(); Console.WriteLine("Example #2: Convert.ToDateTime(expression)"); DateTime date2 = Convert.ToDateTime("3:08:40 PM"); Console.WriteLine(date2); // Returns 1/1/0001 3:08:40 PM //write blank line to make output easier to read Console.WriteLine(); Console.WriteLine("Example #3: Convert.ToDateTime(expression)"); DateTime date3 = Convert.ToDateTime("September 12, 2011 3:08:40 PM"); Console.WriteLine(Convert.ToDateTime(date3)); // Returns September 12, 2011 3:08:40 PM //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 myclsConvertToDateTime As New clsConvertToDateTime myclsConvertToDateTime.Main() End Sub End Module |

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
