如何：添加和处理命令

项目
06/09/2015

Visual Studio 2013 中已弃用 Visual Studio 的外接程序。你应该升级外接程序到 VS 的扩展包。有关升级的更多信息，请参见。常见问题：将外接程序转换为 VSPackage 扩展

下列对象允许您在 Visual Studio 菜单和工具栏上创建、处理和操作命令。

对象名	描述
IDTCommandTarget	对通过使用 AddNamedCommand2 方法添加到集成开发环境 (IDE) 的命令，提供确定此命令的状态或执行此命令的方法。
Commands2	表示 IDE 中的所有命令。
Command	表示 IDE 中的命令。
CommandEvents	为外接程序提供命令事件。
CommandBarEvents	为单击命令栏上的控件时所进行的操作提供一个 Click 事件。

备注

如果您的命令不再显示在相应的命令栏上，或者添加一个新命令或修改现有命令，或者希望重新创建命令，请关闭 Visual Studio 的所有实例，并双击包含外接程序源代码的文件夹中名为 ReCreateCommands.reg 的文件。

使用这些对象，可以：

添加或移除 Visual Studio IDE 中的命令栏（AddCommandBar 和 RemoveCommandBar 方法）。
将新命名的命令添加到工具栏或菜单（AddNamedCommand2 方法）中。
调用命令或命名命令（Raise 和 Exec 方法）。
获取命令的状态（CommandInfo 和 QueryStatus 方法）。

备注

无法为 CommandBar 控件连接 CommandBarEvents 事件，该控件为通过 AddNamedCommand2 添加的新命令而创建。

备注

显示的对话框和菜单命令可能会与“帮助”中的描述不同，具体取决于您现用的设置或版本。这些过程是在“常规开发设置”处于活动状态时开发的。若要更改设置，请在“工具”菜单上选择“导入和导出设置”。有关详细信息，请参阅在 Visual Studio 中自定义开发设置。

示例

下面的示例使用：

Command 对象。
AddNamedCommand 方法。
AddControl 方法。
IDTCommandTarget 接口。
IDTCommandTarget.Exec 方法。
IDTCommandTarget.QueryStatus 方法。

此过程演示如何将外接程序以命令的形式显示在 Visual Studio 中的**“工具”**菜单上。将代码的第一部分添加到您创建的外接程序的 OnConnection 方法中。在 Exec 和 QueryStatus 方法中，请确保 If cmdName = "MyAddin1.Connect.MyAddin1" Then 这一行代码反映您的外接程序的名称。
