C-Sharp Format Example - Format - Sample Code

Description: Illustrates the C# Syntax for Format.

Example Class Main:

using System;
public class clsFormat
{
 
    public void Main()
    {
 
 
        //****************************************************************************************
        // Example #1: 	Format(Expession,style) - returns a formatted string 
        // expression - required. object. any valid expression
        // style - optional. string.  A valid named or user-defined format String expression.
        //
        //Different Formats for Different Numeric Values
        // A user-defined format expression for numbers can have from one to three sections 
        // separated by semicolons. If the Style argument of the Format function contains one
        // of the predefined numeric formats, only one section is allowed.
        //
        // If you use             This is the result
        // One section only       The format expression applies to all values.
        // Two(sections)          The first section applies to positive values and zeros; 
        //                        the second applies to negative values.
        // Three(sections)        The first section applies to positive values, the second 
        //                        applies to negative values, and the third applies to zeros.
        //
        //****************************************************************************************
 
        Console.WriteLine("Example #1: 	Format(Expression,style) $#,##0;;\\Z\\e\\r\\o");
 
        string strStyle = "$#,##0;;\\Z\\e\\r\\o";
 
 
 
        // Return 
        Console.WriteLine(Microsoft.VisualBasic.Strings.Format(1, strStyle)); //Returns $1
        Console.WriteLine(Microsoft.VisualBasic.Strings.Format(-1, strStyle)); //Returns -$1
        Console.WriteLine(Microsoft.VisualBasic.Strings.Format(0, strStyle)); //Returns Zero
 
 
        //write blank line to make output easier to read
        Console.WriteLine();
 
        // Predefined Numeric Formats
        // The following table identifies the predefined numeric format names. These may be used 
        // by name as the Style argument for the Format function:
        //
        // Format(name)                Description()
        // General Number , G, or g    Displays number with no thousand separator.
        // For example, Format(&H3FA, "g") returns 1018.
        //
        // Currency , C, or c          Displays number with thousand separator, if appropriate; 
        // displays two digits to the right of the decimal separator. Output is based on system locale 
        // settings. For example, Format(92346, "c") returns $92,346.00.
        // 
        // Fixed , F, or f             Displays at least one digit to the left and two digits to 
        // the right of the decimal separator. For example, Format(4375, "f") returns 4375.00.
        //
        // Standard , N, or n          Displays number with thousand separator, at least one 
        // digit to the left and two digits to the right of the decimal separator.
        // For example, Format(5674, "n") returns 5,674.00.
        // 
        // Percent()                   Displays number multiplied by 100 with a percent sign 
        // (%) appended immediately to the right; always displays two digits to the right of the 
        // decimal separator. For example, Format(0.5979, "Percent") returns 59.79%.
        //
        // P , or p                    Displays number with thousandths separator multiplied by
        // 100 with a percent sign (%) appended to the right and separated by a single space; 
        // always displays two digits to the right of the decimal separator.
        // For example, Format(0.90345, "p") returns 90.35 %.
        //
        // Scientific()                Uses standard scientific notation, providing two 
        // significant digits. For example, Format(1234567, "Scientific") returns 1.23E+06.
        // E , or e                    Uses standard scientific notation, providing six 
        // significant digits. For example, Format(1234567, "e") returns 1.234567e+006.
        //
        // D , or d                    Displays number as a string that contains the value of 
        // the number in Decimal (base 10) format. This option is supported for integral types
        // (Byte, Short, Integer, Long) only. For example, Format(&H7F, "d") returns 127.
        //
        // X , or x                    Displays number as a string that contains the value of 
        // the number in Hexadecimal (base 16) format. This option is supported for integral 
        // types (Byte, Short, Integer, Long) only. For example, Format(127, "x") returns 7f.
        //
        // Yes/No                      Displays No if number is 0; otherwise, displays Yes.
        // For example, Format(3, "Yes/No") returns Yes.
        //
        // True/False                  Displays False if number is 0; otherwise, displays True.
        // For example, Format(0, "True/False") returns False.
        //
        // On/Off                      Displays Off if number is 0; otherwise, displays On.
        // For example, Format(0, "On/Off") returns Off.
 
 
        //User-Defined Numeric Formats
        //
        // The following table identifies characters you can use to create user-defined number 
        // formats. These may be used to build the Style argument for the Format function:

        // Character()                   Description()
        //
        // None()                        Displays the number with no formatting.
        // (0)                           Digit placeholder. Displays a digit or a zero.
        // (#)                           Digit placeholder. Displays a digit or nothing. 
        // (.)                           Decimal placeholder. The decimal placeholder determines 
        // how many digits are displayed to the left and right of the decimal separator. 
        // (%)                           Percent placeholder. Multiplies the expression by 100. 
        // The percent character (%) is inserted in the position where it appears in the format string.
        // (,)                           Thousand separator.
        // (:)                           Time separator.
        // (/)                           Date separator. 
        // (E- E+ e- e+)                 Scientific format.
