Question

从加载项中，我们可以使用以下方式获取解决方案路径。

_applicationObject = (DTE2)application;  // retrieved from OnConnection method
string solutionDir = System.IO.Path.GetDirectoryName(_applicationObject.Solution.FullName);

您将如何通过编辑器分类器项目（Visual C＃ - ＆gt;可扩展性 - ＆gt;编辑器分类器）执行此操作？

我无法从应用程序或使用getService方法获取DTE对象。

有人可以帮帮我吗？提前谢谢。

 internal class TestQuickInfoSource : IQuickInfoSource
    {
        private TestQuickInfoSourceProvider m_provider;
        private ITextBuffer m_subjectBuffer;
        private Dictionary<string, string> m_dictionary;
        private bool m_isDisposed;
        private DTE2 _applicationObject;

        [Import]
        internal SVsServiceProvider ServiceProvider = null;

        //constructor that initializes the dictionary
        public TestQuickInfoSource(TestQuickInfoSourceProvider provider, ITextBuffer subjectBuffer)
        {
            m_provider = provider;
            m_subjectBuffer = subjectBuffer;

              **// HERE the dictionary with the tool-tip info is created. I would need the solution path here ideally so that I can dynamically create the dictionary from a file there. Following commented statements.**

            // Get an instance of the currently running Visual Studio IDE
            //DTE dte = (DTE)ServiceProvider.GetService(typeof(DTE));
            //string solutionDir = System.IO.Path.GetDirectoryName(dte.Solution.FullName);

            //DTE dte = (DTE)ServiceProvider.GetService(typeof(EnvDTE.DTE));

            //string solutionPath = Path.GetDirectoryName(dte.Solution.FullName);

            //_applicationObject = (DTE2)provider;

            //string solutionPath = Path.GetDirectoryName(_applicationObject.Solution.FullName);            


            //string gg = System.Reflection.Assembly.GetExecutingAssembly().ToString();

            //string solutionDirectory = ((EnvDTE.DTE)System.Runtime
            //                                  .InteropServices

            //                                  .GetActiveObject("VisualStudio.DTE.10.0"))

            //EnvDTE.DTE dte = (EnvDTE.DTE)System.Runtime.InteropServices.Marshal.GetActiveObject("VisualStudio.DTE");
            //string solutionDir = System.IO.Path.GetDirectoryName(dte.Solution.FullName);

            //_applicationObject = (DTE2)dte;

            //string solutionDir1 = System.IO.Path.GetDirectoryName(_applicationObject.Solution.FullName);


            string startupPath = System.IO.Directory.GetCurrentDirectory();

            //EnvDTE.DTE dte = (EnvDTE.DTE)GetService(typeof(EnvDTE.DTE));
            //System.IO.Path.GetDirectoryName(dte.Solution.FullName);

            //Reading Resource File
            //string path = "";



            //EnvDTE80.DTE2 dte2;
            //dte2 = (EnvDTE80.DTE2)System.Runtime.InteropServices.Marshal.GetActiveObject("VisualStudio.DTE.10.0");

            //_applicationObject = (DTE2)dte2;

            //if (_applicationObject.ActiveDocument != null)
            //{
           //    string y = _applicationObject.ActiveDocument.ToString();
            //    string solutionPat = Path.GetDirectoryName(dte2.Solution.FullName);                
            //}

            //Connect objConnect = new Connect();
            //Array objArray = null;
            //objConnect.OnConnection(dte2, ext_ConnectMode.ext_cm_AfterStartup, null, ref objArray);


            //these are the method names and their descriptions
            m_dictionary = new Dictionary<string, string>();
            m_dictionary.Add("add", "int add(int firstInt, int secondInt)\nAdds one integer to another.");
            m_dictionary.Add("subtract", "int subtract(int firstInt, int secondInt)\nSubtracts one integer from another.");
            m_dictionary.Add("multiply", "int multiply(int firstInt, int secondInt)\nMultiplies one integer by another.");
            m_dictionary.Add("divide", "int divide(int firstInt, int secondInt)\nDivides one integer by another.");
            m_dictionary.Add("#include", "Custom Tool-Tip !");
        }

Answer 1

您可以使用GetGlobalService，因此：

var dte2 = (DTE2)Microsoft.VisualStudio.Shell.Package.GetGlobalService(typeof(SDTE));

但是你通常这样做的方式是由@Srikanth Venugopalan给出的。如果你得到＆＃34; NULL＆＃34;，那就错了，而且在不知道更多的情况下，很难提供帮助。

Answer 2

您可以尝试导入SVsServiceProvider并使用GetService方法获取实例

This walkthrough为您提供了如何获取DTE对象引用的说明。

获得DTE引用后，其余部分应与您在add-n中的操作类似。
