Step 1: Click on C# to Cut-n-paste code into clsFormatPercent.cs

using System;
public class clsFormatPercent
{
 
    public void Main()
    {
 
 
        //****************************************************************************************
        // Syntax: 	FormatPercent (Expression As Object, _
        // NumDigitsAfterDecimal As Integer, _
        // IncludeLeadingDigit As TriState, _
        // UseParensForNegativeNumbers As TriState, _
        // GroupDigits As TriState _
        // ) As String
        //
        // Returns an expression formatted as a percentage (that is, multiplied by 100) with 
        // a trailing % character.
        // 
        // Expression - Required - Expression to be formatted
        // NumDigitsAfterDecimal - Optional - Numeric value indicating how many places are displayed
        // to the right of the decimal. Default value is –1, which indicates that the computer's 
        // regional settings are used.
        // IncludeLeadingDigit - Optional. TriState enumeration that indicates whether or not a 
        // leading zero is displayed for fractional values. 
        // UseParensForNegativeNumbers - Optional. TriState enumeration that indicates whether 
        // or not to place negative values within parentheses. 
        // GroupDigits - Optional. TriState enumeration that indicates whether or not numbers are
        // grouped using the group delimiter specified in the computer's regional settings. 
        //****************************************************************************************
 
        Console.WriteLine("Example #1: 	FormatPercent (Expression As Object," + " NumDigitsAfterDecimal As Integer," + " IncludeLeadingDigit As TriState," + " UseParensForNegativeNumbers As TriState," + " GroupDigits As TriState " + " ) As String ");
        double dblNumber = -5432.43;
 
        // Returns "(543,243.000)".
        Console.WriteLine(Microsoft.VisualBasic.Strings.FormatPercent(dblNumber, 3, Microsoft.VisualBasic.TriState.UseDefault, Microsoft.VisualBasic.TriState.True, Microsoft.VisualBasic.TriState.True));
 
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
 
 
        //Prevent console from closing before you press enter
        Console.ReadLine();
 
    }
 
 
}

Step 2: Click on C# to Cut-n-paste code into Program.cs

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
 
namespace CSharp_Syntax
{
    class Program
    {
        static void Main(string[] args)
        {
 
 
            clsFormatPercent myFormatPercent = new clsFormatPercent();
            myFormatPercent.Main();
 
        }
    }
}

Prerequistes:

  1. Install C# (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 Program.cs

Instructions:

  1. Use C# 2010 Express or Standard Edition
  2. Create new project;
    • Click File/New Project
    • Select Console Application Template
    • Select C# for Language
    • name of project could be CSharp_Syntax.
  3. CS Syntax File Directory Binary File Read Sequential

  4. Add New folder named “StringManipulation”
    • Right-click project name in solution explorer;
    • add new folder;
    • name of folder could be: StringManipulation
  5. Add Class Named clsFormatPercent to StringManipulation folder
    • Right-click StringManipulation folder;
    • add new item;
    • Select class
    • Class name could be clsFormatPercent
  6. Click on C# in code in step 1 at top of page to copy code into clsFormatPercent.cs
  7. Click on C# in step 2 at top of page to copy code into Program.cs
  8. Click green arrow or press F5 to run program
