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);

        }

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。

http://www.cnblogs.com/dragon/archive/2005/04/01/130204.html

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!");



            



        }
