name	String	A string that specifies the style name.

Returns

Type	Description
Style	A Style object that specifies the new style.

Remarks

A workbook’s style collection (IWorkbook.Styles) contains Microsoft® Excel® built-in styles by default. The BuiltInStyleId enumerator lists these predefined styles. You can use the Add method to extend the style collection with custom styles.

When you name a style, take into account the following restrictions:

• A style name must be unique. To ensure that StyleCollection does not contain a style with the specified name, use the StyleCollection.Contains method.
• A style name must be non-empty.

All settings of the created Style object except name (Style.Name) are the same as in the Normal default style. To set required formatting characteristics for the style, modify the corresponding properties of the Style object within the Formatting.BeginUpdate - Formatting.EndUpdate paired method calls.

To create a new style based on the existing style, use the Style.CopyFrom method.

For details on how to create and modify styles, see the How to: Create or Modify a Style document.

Example

Use the StyleCollection.Add method of the Workbook.Styles collection to create a new style with a given name. The style’s format settings are identical to the Normal built-in style. Use the Style object’s properties to specify format characteristics for the new style.
