如何在 VSIX 项目中的解决方案文件夹中获取项目

您好，我在 Visual Studio 扩展内的自定义构建任务遇到问题。我需要识别我的自定义项目类型的项目。如果它们位于解决方案的根目录中，我可以很好地做到这一点，但是当它位于解决方案文件夹内时，就会出现问题。我可以将解决方案文件夹作为 EnvDTE.Project 获取，但不确定如何从该文件夹中获取项目。

我以为我可以从项目集合属性中获取它，但它是空的。

任何帮助将不胜感激。

if (Scope == EnvDTE.vsBuildScope.vsBuildScopeSolution)
{
    DTE2 dte2 = Package.GetGlobalService(typeof(EnvDTE.DTE)) as DTE2;
    var sol = dte2.Solution;
    EnvDTE.DTE t = dte2.DTE;
    var x = t.Solution.Projects;
    foreach(var proj in x)
    {
       try
       {
           var project = proj as EnvDTE.Project;
           var guid = GetProjectTypeGuids(project);
           if (guid.Contains("FOLDERGUID"))
           {
               //here is where I would get the project from the folder
           }

我通过更多的研究和一些尝试和错误设法解决了这个问题。如果其他人遇到这个问题，我将主要代码更改为

if (Scope == EnvDTE.vsBuildScope.vsBuildScopeSolution)
{
    errorListProvider.Tasks.Clear();
    DTE2 dte2 = Package.GetGlobalService(typeof(DTE)) as DTE2;
    var sol = dte2.Solution;
    var projs = sol.Projects;
    foreach(var proj in sol)
    {
         var project = proj as Project;
         if (project.Kind == ProjectKinds.vsProjectKindSolutionFolder)
         {
             var innerProjects = GetSolutionFolderProjects(project);
             foreach(var innerProject in innerProjects)
             {
                 //carry out actions here.
             }
         }
    }
}

GetSolutionFolderForProjects 的代码是

private IEnumerable<Project> GetSolutionFolderProjects(Project project)
{
    List<Project> projects = new List<Project>();
    var y = (project.ProjectItems as ProjectItems).Count;
    for(var i = 1; i <= y; i++)
    {
        var x = project.ProjectItems.Item(i).SubProject;
        var subProject = x as Project;
        if (subProject != null)
        {
          //Carried out work and added projects as appropriate
        }
    }

    return projects;
}

希望这对其他人有帮助。
