Purpose: – Illustrates the C# Syntax for FormatCurrency.
Step 1: Click on C# to Cut-n-paste code into clsFormatCurrency.cs
using System; public class clsFormatCurrency { public void Main() { //**************************************************************************************** // Syntax: FormatCurrency (Expression As Object, _ // NumDigitsAfterDecimal As Integer, _ // IncludeLeadingDigit As TriState, _ // UseParensForNegativeNumbers As TriState, _ // GroupDigits As TriState _ // ) As String // // 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: FormatCurrency (Expression As Object," + " NumDigitsAfterDecimal As Integer," + " IncludeLeadingDigit As TriState," + " UseParensForNegativeNumbers As TriState," + " GroupDigits As TriState " + " ) As String "); double dblNumber = -5432.43; // Returns "($5,432.43)". Console.WriteLine(Microsoft.VisualBasic.Strings.FormatCurrency(dblNumber, -1, 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) { clsFormatCurrency myFormatCurrency = new clsFormatCurrency(); myFormatCurrency.Main(); } } } |
Prerequistes:
- Install C# (Express or Standard Edition)

- 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 Program.cs
