Purpose: – Illustrates using C-Sharp ConvertToString Code Example.
Purpose:
Converts boolean, date, and numeric data types into String data type
Syntax:
Convert.ToString(expression)
Convert.ToString(expression)
| Parameters | Description | expression | boolean, date, and numeric data types |
|---|
| Result Data Type | Description | String | 1. If boolean, returns string “True” or “False” 2. If date, returns A string containing a date value (date and time) in the short date format of your system 3. If number, returns a string representing the number |

Console.WriteLine("Example #1: Convert.ToString(expression) - boolean");
bool myBool = true;
string String1 = Convert.ToString(myBool);
Console.WriteLine(String1); // Returns "True"
//write blank line to make output easier to read
Console.WriteLine();
Console.WriteLine("Example #2: Convert.ToString(expression) - date");
DateTime myDate = Convert.ToDateTime("10/21/2011");
string String2 = Convert.ToString(myDate);
Console.WriteLine(String2); // Returns 10/21/2011
//write blank line to make output easier to read
Console.WriteLine();
Console.WriteLine("Example #3: Convert.ToString(5.5) - number");
string String3 = Convert.ToString(5.5);
Console.WriteLine(Convert.ToString(String3)); // Returns 5.5
//Prevent console from closing before you press enter
Console.ReadLine();

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
Instructions:
- Use C-Sharp 2010 Express or Standard Edition
- Create new project;
- Click File/New Project
