如何从编辑器分类器项目(c#)中获取当前解决方案目录

Question

从外接程序中，我们可以使用以下方法获得解路径:

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

如何通过编辑器分类器项目 (Visual c# ->可扩展性->编辑器分类器)做到这一点?

我无法从应用程序或使用getService方法获得DTE对象。

有人能帮我一下吗?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;

        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));

            //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，如下:

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

但是你通常做的方式，是由@Srikanth Venugopalan给出的。如果你得到"NULL"，那就有问题，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

本演练向您展示了如何获取对DTE对象的引用。

一旦您有了DTE引用，其余的应该与您在add-n中所做的类似。
