首先我们使用向导生成一个package的扩展，里面就会发现一个vsct文件。vsct文件的全称是Visual Studio Command Table，它其实就是一个xml文件，通过一定的规则来描述visual Studio的command布局。

 

添加一个菜单项：

首先我们在vsct文件你们加一个菜单项：

<?xml version="1.0" encoding="utf-8"?>

<CommandTable xmlns="http://schemas.microsoft.com/VisualStudio/2005-10-18/CommandTable" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <Extern href="stdidcmd.h"/>

    <Extern href="vsshlids.h"/>

    <Commands package="vsPackage">

        <Groups>

            <Group guid="cmdSet" id="MyMenuGroup" priority="0x0600">

                <Parent guid="guidSHLMainMenu" id="IDM_VS_MENU_TOOLS"/>

            </Group>

        </Groups>

        <Buttons>

            <Button guid="cmdSet" id="cmdidMyCommand" priority="0x0100" type="Button">

                <Parent guid="cmdSet" id="MyMenuGroup" />

                <Strings>

                    <ButtonText>我的工具箱</ButtonText>

                </Strings>

            </Button>

        </Buttons>

    </Commands>

    <Symbols>

        <GuidSymbol name="vsPackage" value="{0b468468-bf83-4dc6-9253-ca5970142e5d}" />

        <GuidSymbol name="cmdSet" value="{b001c53d-3e2d-4c8f-9787-73ed59a7c412}">

            <IDSymbol name="MyMenuGroup" value="0x1020" />

            <IDSymbol name="cmdidMyCommand" value="0x0100" />

        </GuidSymbol>

    </Symbols>

</CommandTable>

其中高亮部分就是我添加的内容，执行效果如下：

 

再次添加一个菜单项：

再次添加一个菜单项也是非常简单的，只要在Buttons里面增加一项即可：

<?xml version="1.0" encoding="utf-8"?>

<CommandTable xmlns="http://schemas.microsoft.com/VisualStudio/2005-10-18/CommandTable" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <Extern href="stdidcmd.h"/>

    <Extern href="vsshlids.h"/>

    <Commands package="vsPackage">

        <Groups>

            <Group guid="cmdSet" id="MyMenuGroup" priority="0x0600">

                <Parent guid="guidSHLMainMenu" id="IDM_VS_MENU_TOOLS"/>

            </Group>

        </Groups>

        <Buttons>

            <Button guid="cmdSet" id="cmdidMyCommand" priority="0x0100" type="Button">

                <Parent guid="cmdSet" id="MyMenuGroup" />

                <Strings>

                    <ButtonText>我的工具箱</ButtonText>

                </Strings>

            </Button>

            <Button guid="cmdSet" id="cmdidMyCommand2" priority="0x0101" type="Button">

                <Parent guid="cmdSet" id="MyMenuGroup" />

                <Strings>

                    <ButtonText>我的工具箱2</ButtonText>

                </Strings>

            </Button>

        </Buttons>

    </Commands>

    <Symbols>

        <GuidSymbol name="vsPackage" value="{0b468468-bf83-4dc6-9253-ca5970142e5d}" />

        <GuidSymbol name="cmdSet" value="{b001c53d-3e2d-4c8f-9787-73ed59a7c412}">

            <IDSymbol name="MyMenuGroup" value="0x1020" />

            <IDSymbol name="cmdidMyCommand" value="0x0100" />

            <IDSymbol name="cmdidMyCommand2" value="0x0101" />

        </GuidSymbol>

    </Symbols>

</CommandTable>

生成的效果如下：

 

添加分组

现在我们来把菜单进行分组：首先在Groups项中添加一个Group，然后修改Button的ParentId即可。

<?xml version="1.0" encoding="utf-8"?>

<CommandTable xmlns="http://schemas.microsoft.com/VisualStudio/2005-10-18/CommandTable" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <Extern href="stdidcmd.h"/>

    <Extern href="vsshlids.h"/>

    <Commands package="vsPackage">

        <Groups>

            <Group guid="cmdSet" id="MyMenuGroup" priority="0x0600">

                <Parent guid="guidSHLMainMenu" id="IDM_VS_MENU_TOOLS"/>

            </Group>

            <Group guid="cmdSet" id="MyMenuGroup2" priority="0x0601">

                <Parent guid="guidSHLMainMenu" id="IDM_VS_MENU_TOOLS"/>

            </Group>

        </Groups>

        <Buttons>

            <Button guid="cmdSet" id="cmdidMyCommand" priority="0x0100" type="Button">

                <Parent guid="cmdSet" id="MyMenuGroup" />

                <Strings>

                    <ButtonText>我的工具箱</ButtonText>

                </Strings>

            </Button>

            <Button guid="cmdSet" id="cmdidMyCommand2" priority="0x0101" type="Button">

                <Parent guid="cmdSet" id="MyMenuGroup2" />

                <Strings>

                    <ButtonText>我的工具箱2</ButtonText>

                </Strings>

            </Button>

        </Buttons>

    </Commands>

    <Symbols>

        <GuidSymbol name="vsPackage" value="{0b468468-bf83-4dc6-9253-ca5970142e5d}" />

        <GuidSymbol name="cmdSet" value="{b001c53d-3e2d-4c8f-9787-73ed59a7c412}">

            <IDSymbol name="MyMenuGroup" value="0x1020" />

            <IDSymbol name="MyMenuGroup2" value="0x1021" />

            <IDSymbol name="cmdidMyCommand" value="0x0100" />

            <IDSymbol name="cmdidMyCommand2" value="0x0101" />

        </GuidSymbol>

    </Symbols>

</CommandTable>

效果如下：

 

在菜单中添加图标

在菜单中添加图标要稍微麻烦点：首先需要添加一个Bitmaps分组，然后修改Button的Icon属性。

<?xml version="1.0" encoding="utf-8"?>

<CommandTable xmlns="http://schemas.microsoft.com/VisualStudio/2005-10-18/CommandTable" xmlns:xs="http://www.w3.org/2001/XMLSchema">

    <Extern href="stdidcmd.h"/>

    <Extern href="vsshlids.h"/>

    <Commands package="vsPackage">

        <Groups>

            <Group guid="cmdSet" id="MyMenuGroup" priority="0x0600">

                <Parent guid="guidSHLMainMenu" id="IDM_VS_MENU_TOOLS"/>

            </Group>

            <Group guid="cmdSet" id="MyMenuGroup2" priority="0x0601">

                <Parent guid="guidSHLMainMenu" id="IDM_VS_MENU_TOOLS"/>

            </Group>

        </Groups>

        <Buttons>

            <Button guid="cmdSet" id="cmdidMyCommand" priority="0x0100" type="Button">

                <Parent guid="cmdSet" id="MyMenuGroup" />

                <Icon guid="guidImages" id="bmpPic1" />

                <Strings>

                    <ButtonText>我的工具箱</ButtonText>

                </Strings>

            </Button>

            <Button guid="cmdSet" id="cmdidMyCommand2" priority="0x0101" type="Button">

                <Parent guid="cmdSet" id="MyMenuGroup2" />

                <Icon guid="guidImages" id="bmpPicSearch" />

                <Strings>

                    <ButtonText>我的工具箱2</ButtonText>

                </Strings>

            </Button>

        </Buttons>

        <Bitmaps>

            <Bitmap guid="guidImages" href="Resources\Images.png" usedList="bmpPic1, bmpPic2, bmpPicSearch, bmpPicX, bmpPicArrows"/>

        </Bitmaps>

    </Commands>

    <Symbols>

        <GuidSymbol name="vsPackage" value="{0b468468-bf83-4dc6-9253-ca5970142e5d}" />

        <GuidSymbol name="cmdSet" value="{b001c53d-3e2d-4c8f-9787-73ed59a7c412}">

            <IDSymbol name="MyMenuGroup" value="0x1020" />

            <IDSymbol name="MyMenuGroup2" value="0x1021" />

            <IDSymbol name="cmdidMyCommand" value="0x0100" />

            <IDSymbol name="cmdidMyCommand2" value="0x0101" />

        </GuidSymbol>

        <GuidSymbol name="guidImages" value="{f3517729-ad9a-4c24-9f72-288fafa0758d}" >

            <IDSymbol name="bmpPic1" value="1" />

            <IDSymbol name="bmpPic2" value="2" />

            <IDSymbol name="bmpPicSearch" value="3" />

            <IDSymbol name="bmpPicX" value="4" />

            <IDSymbol name="bmpPicArrows" value="5" />

            <IDSymbol name="bmpPicStrikethrough" value="6" />

        </GuidSymbol>

    </Symbols>

</CommandTable>

生成的效果如下：

 

在菜单中关联命令

通过向导生成Package时，会自动生成一个Package的子类，重载其Initialize函数，在里面加入事件处理函数即可。向导默认已经给我们生成了一个示例，我们只需要修改其处理函数和添加新的按钮的事件即可。

    protected override void Initialize()

    {

        base.Initialize();

        // Add our command handlers for menu (commands must exist in the .vsct file)

        OleMenuCommandService mcs = GetService(typeof(IMenuCommandService)) as OleMenuCommandService;

        if (null != mcs)

        {

            // Create the command for the menu item.

            CommandID menuCommandID = new CommandID(GuidList.guidVSPackage3CmdSet, (int)PkgCmdIDList.cmdidMyCommand);

            MenuCommand menuItem = new MenuCommand((s, e) => System.Windows.Forms.MessageBox.Show("hello world"), menuCommandID);

            mcs.AddCommand(menuItem);

        }

    }
