Visual Studio 插件开发

先上个效果图：，类似的对应的google的扩展程序。

环境：win10，vs2017 如果是其他版本的就不知道有没有对应的模板。(如果没有可能需要下载一下对应的模板)

第一步：新建项目

新建好以后会出现一个页面：大概意思插件的

一些介绍。

第2步：对着项目右击【添加项】

 需求：给js，css 添加版本号.

code：里面用到了 HtmlAgilityPack   添加引用 nuget

Install-Package HtmlAgilityPack -Version 1.11.12

       /// <summary>
        /// This function is the callback used to execute the command when the menu item is clicked.
        /// See the constructor to see how the menu item is associated with this function using
        /// OleMenuCommandService service and MenuCommand class.
        /// </summary>
        /// <param name="sender">Event sender.</param>
        /// <param name="e">Event args.</param>

        {
            //获取服务，这玩意儿……可以理解为vs的服务对象吧。
            var dte = this.ServiceProvider.GetService(typeof(DTE)) as DTE;
            var selection = dte.ActiveDocument.Selection as TextSelection;//当前文档中选中的部分
            if (selection == null)
            {

                newcontent.Append("<script src="" + src + ""></script>

            }
        }

修改配置信息 ：绑定的键盘快捷方式菜单 注意guid 和id 有点要求一致

        it is possible to define includes and macros with the same syntax used
        in C++ files. Using this ability of the compiler here, we include some files
        defining some of the constants that we will use inside the file. -->

代码写好以后，按 f5 会启动一个新的vs  打开你需要调试操作新的解决方案 (比如这里给js 或者css添加版本号 要先选中) 按快捷键alt+j 或者在工具里面 调试就会进入 MenuItemCallback方法。

安装：在bin 或者 Release目录下找到  【xx.vsix】双击安装就好了 

 附近信息：

code无误 安装后最后结果如图：

 扩展：比如实现代码自动补全 （ibatis） 一下新的语法 但是写的不熟悉 等等。 这里只是抛砖引玉
