C-Sharp FormatCurrency Syntax Example | ASP.NET C# String Method | Source Code
Purpose: – Here is a FormatCurrency Example that illustrates the C# Syntax in ASP.NET.
Step 1: Click on C# to Cut-n-paste code into FormatCurrency.aspx.cs
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; // This example is from http://idealprogrammer.com // It shows how you can use FormatCurrency syntax in C-Sharp ASP.NET //**************************************************************************************** // 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. //**************************************************************************************** public partial class StringManipulation_FormatCurrency : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Label1.Text = "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)". Label2.Text = Microsoft.VisualBasic.Strings.FormatCurrency(dblNumber, -1, Microsoft.VisualBasic.TriState.UseDefault, Microsoft.VisualBasic.TriState.True, Microsoft.VisualBasic.TriState.True); //Returns Zero } } |
