Assembly: Microsoft.Office.Interop.Excel (in microsoft.office.interop.excel.dll)
Each Style object represents a style description for a range. The Style object contains all style attributes (font, number format, alignment, and so on) as properties. There are several built-in styles — including Normal, Currency, and Percent — which are listed in the Style name box in the Style dialog box (Format menu).
Use the Styles property to return the Styles collection.
Use the Add method to create a new style and add it to the collection.
Use Styles(index), where index is the style index number or name, to return a single Style object from the workbook Styles collection.
