项目
09/04/2008

更新：2007 年 11 月

表示 Microsoft Office Excel 中的智能标记。

命名空间： Microsoft.Office.Tools.Excel
程序集： Microsoft.Office.Tools.Excel.v9.0（在 Microsoft.Office.Tools.Excel.v9.0.dll 中）

语法

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

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

备注

SmartTag 类是代表 Excel 工作簿中的智能标记的抽象 SmartTagBase 类的实现。有关 Visual Studio Tools for Office 解决方案中的智能标记的信息，请参见智能标记的结构。

示例

下面的代码示例演示如何创建您自己的从 SmartTag 派生的自定义智能标记类。该示例重写 Recognize 方法以识别在某个单元格中找到的第一个智能标记术语。此示例假设您已从“添加引用”对话框的“COM”选项卡添加一个对“Microsoft Smart Tags 2.0 类型库”的引用。有关直接使用 SmartTag 类的代码示例，请参见 Action 类。
