VSPackge插件系列：常用IDE功能的封装

继上一篇VSPackge插件系列简单介绍如何正确的获取DTE之后，就一直没发VSPackge插件系列的文章了，最近同事也想了解如何在代码中与VS交互，特发一篇文章示例一些简单功能是如何调用，也以备以后查阅之用。

为了方便的调用vs的提供的服务，我这里写了一个类对vs的一些常用功能进行封装了，像什么当前选择项，当前编辑器，当前窗口，输出窗口的调用等等。还有解决方案里的选择改变事件的监听等等，更多功能还待挖掘中。

    public class Ide    {        private Ide()        {            _dte2 = (DTE2)ServiceProvider.GlobalProvider.GetService(typeof(DTE));            _dte2.Events.SelectionEvents.OnChange += new _dispSelectionEvents_OnChangeEventHandler(SelectionEvents_OnChange);        }        #region Singlton        private static Ide _Ide = new Ide();        public static Ide Instance        {            get            {                return _Ide;            }        }        #endregion        #region Propertys        private DTE2 _dte2 = null;        public DTE2 DTE2         {             get             {                return _dte2;            }        }        public Window ActiveWindow        {            get            {                CheckDTE();                return _dte2.ActiveWindow;             }        }        public Document ActiveDocument        {            get            {                CheckDTE();                return _dte2.ActiveDocument;            }        }        public IEnumerable<Project> ActiveProjects        {            get            {                CheckDTE();                Array prjs = (Array)_dte2.ActiveSolutionProjects;                foreach (var prj in prjs)                {                    yield return prj as Project;                }            }        }        public Project SelectedProject        {            get            {                if (ActiveProjects.Count() > 1)                {                    throw new Exception("Project is Multi-Selection");                }                return ActiveProjects.FirstOrDefault();            }        }        public ToolWindows ToolWindows        {            get            {                CheckDTE();                return _dte2.ToolWindows;            }        }        /// <summary>        /// 解决方案管理器中显示层次结构树数据的项        /// </summary>        public IEnumerable<UIHierarchyItem> ExplorerSelectedItems        {            get            {                CheckDTE();                Array selectedItems = (Array)_dte2.ToolWindows.SolutionExplorer.SelectedItems;                foreach (var item in selectedItems)                {                    yield return item as UIHierarchyItem;                }            }        }        /// <summary>        /// 返回选择的工程或工程中的项        /// </summary>        public IEnumerable<SelectedItem> SelectedItems        {            get            {                CheckDTE();                SelectedItems selectedItems = _dte2.SelectedItems;                foreach (var item in selectedItems)                {                    yield return item as SelectedItem;                }            }        }        public StatusBar StatusBar        {            get            {                CheckDTE();                return _dte2.StatusBar;            }        }        public OutputWindowPane OutputWindow        {            get            {                var outpanes = ToolWindows.OutputWindow.OutputWindowPanes;                foreach (OutputWindowPane pane in outpanes)                {                    if (pane.Name.Equals("GLIde"))                    {                        return pane;                    }                }                return ToolWindows.OutputWindow.OutputWindowPanes.Add("GLIde");            }        }        public ErrorList ErrorWindow        {            get            {                return ToolWindows.ErrorList;             }        }        private void CheckDTE()        {            if (_dte2 == null)            {                throw new Exception("DTE service not found");            }        }        #endregion        #region Events        public event Action<object, EventArgs> SelectionChanged;        void SelectionEvents_OnChange()        {            if (SelectionChanged != null)            {                SelectionChanged(this, new EventArgs());            }        }        #endregion    }    public static class Extentions    {        public static void WriteLine(this OutputWindowPane outputPane, string context)        {            outputPane.OutputString(context + Environment.NewLine);        }    }

这其中也参考了一篇比较旧的文章，看来研究VS的人不是甚多，不知道是何原因，还是各位大侠私藏了自己的技术。

以下是调用示例代码，状态栏的文本提示，处理动画，获取选中项名称，获取当前选中工程，当前激活窗口等等。

        private void button1_Click(object sender, RoutedEventArgs e)        {            Ide.Instance.StatusBar.Progress(true, "doing something", 90, 100);            Ide.Instance.StatusBar.Animate(true, vsStatusAnimation.vsStatusAnimationDeploy);            //Ide.Instance.StatusBar.Progress(false);            tbDisplay.Text += "SelectedItems:" + Environment.NewLine;            foreach (var item in Ide.Instance.SelectedItems)            {                tbDisplay.Text += item.Name + Environment.NewLine;            }            tbDisplay.Text += "ExplorerSelectedItems:" + Environment.NewLine;            foreach (var item in Ide.Instance.ExplorerSelectedItems)            {                tbDisplay.Text += item.Name + Environment.NewLine;            }            tbDisplay.Text += "ActiveProjects:" + Environment.NewLine;            foreach (var item in Ide.Instance.ActiveProjects)            {                tbDisplay.Text += item.Name + Environment.NewLine;            }            tbDisplay.Text += "ActiveWindow:" + Environment.NewLine;            tbDisplay.Text += Ide.Instance.ActiveWindow.Caption + Environment.NewLine;            //tbDisplay.Text += "ActiveDocument:" + Environment.NewLine;            //tbDisplay.Text += Ide.Instance.ActiveDocument.Name + Environment.NewLine;            //tbDisplay.Text += "SelectedProject:" + Environment.NewLine;            //tbDisplay.Text += Ide.Instance.SelectedProject.Name + Environment.NewLine;            Ide.Instance.OutputWindow.WriteLine("Hello world!");                    }

 欢迎各位提供更多的使用心得，共同进步！
