如何在已经运行的Visual Studio中以编程方式打开项目/解决方案？

Question

The "possible duplicate" aims at opening the file, like in Notepad, I am looking for opening .csproj/.sln file not as just raw text file, but as full project/solution, so for example if my path is for .sln file, entire solution should be opened, not just literally single .sln file.

I open project/solution this way:

var psi = new System.Diagnostics.ProcessStartInfo(path);
System.Diagnostics.Process.Start(psi);

where path is path to project/solution. It works fine, but it launches another Visual Studio to open the given file.

I would like to open project/solution in already running VS (if there is none, in such case, sure launch VS as well).

How to do it?

Answer 1

I'm adding this in case anyone is still looking for the answer to this question, as I was in 2019.

" How to programmatically open project/solution in already running Visual Studio? "

I've also added how to open a folder or a file as well, just for completeness.

Make sure to surround the code containing these statement in a try/catch , to handle path not found etc.

Assuming:

  using EnvDTE;
  using EnvDTE80;
  using Microsoft.VisualStudio.Shell;

  var dte = Package.GetGlobalService(typeof(_DTE)) as DTE2;

1. To programmatically open a solution :

   dte.Solution.Open(path);

2. To programmatically open a project :

  dte.ExecuteCommand("File.OpenProject", path);

3. To programmatically open a folder :

  dte.ExecuteCommand("File.OpenFolder", path);

4. To programmatically open a file :

  dte.ExecuteCommand("File.OpenFile", path);

I hope that helps someone.
