Visual Studio.Net 打开一个工程的时候，有时候子项目很多，而且你有不是很熟悉这个项目。
然后你查找某个关键字，打开一个文件，你需要知道它在Solution Explorer中属于哪里，也就是高亮这个文件节点，
你应该怎么做？这里提供一个办法供你参考。
我们知道 Visual Studio.Net 提供了可扩展性开发的功能，也就是插件功能，比较有名的是Visual AssistX
另外有很多文章介绍如何开发插件，

我的方法是先得到就是从SolutionExplorer的Item中一个个找当前的ProjectItem，然后高亮，很简单。
相关代码如下,请指教

public void Exec(string commandName, vsCommandExecOption executeOption, ref object varIn, ref object varOut, ref bool handled)
2
{

handled = false;
4 if(executeOption == vsCommandExecOption.vsCommandExecOptionDoDefault)
5
{
6 if(commandName == "SyncAddin.Connect.SyncAddin")

8 DoSync();
9 handled = true;
10 return;

}
12 }

}

17 {

20 ProjectItem projectitem = _applicationObject.ActiveDocument.ProjectItem;
21
22 UIHierarchy UIH = _applicationObject.ToolWindows.SolutionExplorer;
23 UIH.Parent.SetFocus();
24
25 // Requires a reference to System.Text.
26 // Set a reference to the first level nodes in Solution Explorer.
