Remarks

The WorksheetBase class is the base class for the Sheetn classes in document-level Excel projects created by using Visual Studio. Use the Sheetn classes to programmatically access the worksheets in your project. The WorksheetBase class is a host item that represents a worksheet in document-level projects. For more information, see Host Items and Host Controls Overview and Worksheet Host Item.

The WorksheetBase class provides the same members as the Microsoft.Office.Interop.Excel.Worksheet class in the Excel primary interop assembly, but it adds the following features:

Creating Worksheet Host Items

You cannot create WorksheetBase objects programmatically in Office projects.

In document-level projects, the Sheetn classes (which derive from WorksheetBase) are instantiated automatically by the Visual Studio Tools for Office runtime when the end user opens the workbook. For more information, see Programming Document-Level Customizations.

In application-level projects, you can create worksheet host items programmatically by using the GetVstoObject method. The worksheet host item you create is a Microsoft.Office.Tools.Excel.Worksheet object, rather than a WorksheetBase object. For more information, see Extending Word Documents and Excel Workbooks in Application-Level Add-ins at Run Time.

Usage

This type is used only in Office projects that target the .NET Framework 4. The assembly that defines this type is not part of the Visual Studio Tools for Office runtime. You must deploy this assembly with your solution. For more information, see Assemblies in the Visual Studio Tools for Office Runtime.

Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
