C-Sharp ConvertToChar Example – Code Sample Syntax

C-Sharp ConvertToChar Example – Code Sample Syntax

Purpose: – Illustrates using C-Sharp ConvertToChar Code Example.

Purpose:
Converts Char or first character of string into Char data type

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

using System;
 
public class clsConvertToChar
{
 
    public void Main()
    {
 
 
        //****************************************************************************************
        // Purpose: Converts Char or first character of string into Char data type
        //
        // Syntax: 	Convert.ToChar(expression)
        //
        // Parameter1: expression - char or string
        //
        // Result: Char - only first character is used when expression is string
        //
        // Quick Example: Convert.ToChar("Test") // Returns T
        //
        //****************************************************************************************
        // This example is from http://idealprogrammer.com
 
        Console.WriteLine("Example #1: 	Convert.ToChar(string)");
 
 
        Console.WriteLine(Convert.ToChar("Test")); // Returns T
 
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
        Console.WriteLine("Example #2: 	Convert.ToChar(char)");
 
        char myChar = '\0';
        myChar = 'A';
        Console.WriteLine(Convert.ToChar(myChar)); // Returns A
 
        //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 myclsConvertToChar As New clsConvertToChar
        myclsConvertToChar.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

Instructions:

1. Use C-Sharp 2010 Express or Standard Edition
2. Create new project;
   • Click File/New Project
   • Select Console Application Template
   • Select C-Sharp for Language
   • name of project could be C-Sharp_Syntax.
3. Add New folder named “Functions”
   • Right-click project name in solution explorer;
   • add new folder;
   • name of folder could be: Functions
4. Add New subfolder named “ConversionFunctions”
   • Right-click Functions folder in solution explorer;
   • add new folder;
   • name of folder could be: ConversionFunctions
5. Add New subfolder named “TypeConversionFunctions”
   • Right-click ConversionFunctions folder in solution explorer;
   • add new folder;
   • name of folder could be: TypeConversionFunctions
6. Add Class Named clsConvertToChar to TypeConversionFunctions folder
   • Right-click TypeConversionFunctions folder;
   • add new item;
   • Select class
   • Class name could be clsConvertToChar
7. Click on cs in code in step 1 above to copy code into clsConvertToChar.cs
