示例

以下示例演示如何使用LinkBehavior枚举设置LinkBehavior属性。 它还演示如何设置ActiveLinkColor、LinkColorText属性以及LinkVisited向 a LinkLabel.LinkCollection添加项。 若要运行此示例，请将其粘贴到空白窗体中，并从窗体的构造函数或Load方法调用InitializeLinkLabel。

注解

控件 LinkLabel 可以在控件的文本中显示多个链接。 使用 Add 此方法可将控件中的 LinkLabel 文本转换为用户可单击的链接，以执行类似于 Button 控件的任务。 此方法将创建的链接添加到LinkLabel.LinkCollection该链接。LinkLabel 例如，如果要在标签文本“快速”中设置单词“quick”，则调用此方法 start 时将参数设置为 4（4）， length 并将参数设置为 5（5）。 然后，“quick”一词将更改为链接，并将链接添加到集合中。 如果要将信息与链接相关联，例如在用户单击链接时要显示的 URL 或要打开的文件，请使用该方法的其他版本 Add 。

示例

下面的代码示例创建一个 LinkLabel 显示链接的控件，并在单击控件文本中定义的链接时在默认浏览器中显示Microsoft网站。 该示例定义一个初始化 LinkLabel 控件的方法，以及一个将处理 LinkClicked 控件事件的方法。 事件的事件处理程序 LinkClicked 使用 LinkData 类的属性 LinkLabel.Link 来确定在默认浏览器中显示的 URL。 此示例要求它位于类 Form 中。

   // Create a new LinkLabel control.

      // Create a new link using the Add method of the LinkCollection class.
