Stellt ein Smarttag in Microsoft Office Excel dar.

Namespace: Microsoft.Office.Tools.Excel
Assembly: Microsoft.Office.Tools.Excel.v9.0 (in Microsoft.Office.Tools.Excel.v9.0.dll)

Syntax

<PermissionSetAttribute(SecurityAction.Demand, Name := "FullTrust")> _
Public Class SmartTag _
    Inherits SmartTagBase

Dim instance As SmartTag

[PermissionSetAttribute(SecurityAction.Demand, Name = "FullTrust")]
public class SmartTag : SmartTagBase

Hinweise

Die SmartTag-Klasse ist eine Implementierung der abstrakten SmartTagBase-Klasse für Smarttags in Excel-Arbeitsmappen. Informationen über Smarttags in Visual Studio Tools for Office-Projektmappen finden Sie unter Smarttagarchitektur.

Beispiele

Im folgenden Codebeispiel wird veranschaulicht, wie Sie eine benutzerdefinierte Smarttagklasse erstellen, die aus SmartTag abgeleitet wird. Im Beispiel wird die Recognize-Methode überschrieben, um den ersten in einer Zelle gefundenen Smarttagbegriff zu erkennen. In diesem Beispiel wird davon ausgegangen, dass Sie von der Registerkarte COM im Dialogfeld Verweis hinzufügen einen Verweis auf die Microsoft Smart Tags 2.0-Typbibliothek hinzugefügt haben. Ein Codebeispiel, in dem die SmartTag-Klasse direkt verwendet wird, finden Sie in der Action-Klasse.
