Remarks
The XlNumberFormat class provides a set of static properties you can use to apply the predefined Excel number format to a cell value. These properties allow you to display a numeric value in a cell as a number (XlNumberFormat.Number, XlNumberFormat.Number2, XlNumberFormat.NumberWithThousandSeparator, etc. ), percentage (XlNumberFormat.Percentage, XlNumberFormat.Percentage2), fraction (XlNumberFormat.Fraction, XlNumberFormat.Fraction2), date (XlNumberFormat.ShortDate, XlNumberFormat.LongDate, XlNumberFormat.MonthYear, etc.), time (XlNumberFormat.ShortTime12, XlNumberFormat.LongTime12, XlNumberFormat.MinuteSeconds, etc.), text (XlNumberFormat.Text) and so on. To get the format code used by the XlNumberFormat object to display a cell value, use the XlNumberFormat.FormatCode property.
If the predefined formats do not meet your demands, you can create a custom number format. To do this, assign the corresponding format string to the XlFormatting.NumberFormat property of the XlCellFormatting object that defines common format settings of a cell. The specified format string will be implicitly converted to the XlNumberFormat object.
To apply the specified number formatting options to a cell, pass the XlNumberFormat object to the IXlCell.ApplyFormatting method as a parameter, or assign it to the IXlCell.Formatting property. For more information on how to apply a number format to a cell value, refer to the How to: Specify Number Format for Cell Content document.
