Get a list of Solution/Project Files for VS Add-in or DXCore Plugin

问题

I am trying to write a add-in for Visual Studio that, among other things, needs to keep track of every file in a Visual Studio solution. I know what events I need to subscribe to (when a Solution is opened, when a file is added/removed/edited in it, the same for projects, etc), but I don't understand how to actually get a list of files from any of it.

I recently installed CodeRush and have been playing with the DXCore framework. I'm very happy with it's approach at plugins, but I still don't see an obvious way to get a list of files in the solution.

So to sum it up: How, via the Visual Studio SDK or DXCore, do I get a reliable list of files in the solution and it's projects?

回答1:

This is all available easily using DTE in the Visual Studio SDK.

You can get a list of projects in a solution using the Projects interface.

You can get a list of items in a project using the ProjectItem interface.

For more information, I'd recommend reading up on Controlling Projects and Solutions.

Thanks, Reed; the article you linked got me far enough to get a proof of concept churned out in a couple minutes.

Since I feel it's related, here is the iteration and recursive means by which I collected the ProjectItems. I did this in DXCore, but the same idea applies to the raw Visual Studio SDK (DXCore is merely a nicer looking wrapper over the SDK). The 'Solution', 'Projects', 'Project', and 'ProjectItem' objects are right there in EnvDTE.

Setting Projects

EnvDTE.Solution solution = CodeRush.ApplicationObject.Solution;
EnvDTE.Projects projects = solution.Projects;

Iterating over the Projects to pull ProjectItems

var projects = myProjects.GetEnumerator();
while (projects.MoveNext())
{
    var items = ((Project)projects.Current).ProjectItems.GetEnumerator();
    while (items.MoveNext())
    {
        var item = (ProjectItem)items.Current;
        //Recursion to get all ProjectItems
        projectItems.Add(GetFiles(item));
    }
}

Finally, The recursion I do for getting all ProjectItems in the active Solution

ProjectItem GetFiles(ProjectItem item)
{
    //base case
    if (item.ProjectItems == null)
        return item;

    var items = item.ProjectItems.GetEnumerator();
    while (items.MoveNext())
    {
        var currentItem = (ProjectItem)items.Current;
        projectItems.Add(GetFiles(currentItem));
    }

    return item;
}

See EnvDTE : Getting all projects (the SolutionFolder PITA)

This solution works brilliantly to get all of the projects in the solution, even if the projects are in subfolders.

Be sure to read the comments below the code, as it points out an essential fix, use this to grab DTE2 instead of the original code, or else it doesn't get the correct instance of Visual Studio:

DTE2 dte2 = Package.GetGlobalService(typeof(DTE)) as DTE2;

(the code was updated to include above fix)
