How do I programmatically list all projects in a solution?

Question

How do I programmatically list all of the projects in a solution? I\'ll take a script, command-line, or API calls.

Answer 1

Here's a PowerShell script that retrieves project details from a .sln file:

Get-Content 'Foo.sln' |
  Select-String 'Project\(' |
    ForEach-Object {
      $projectParts = $_ -Split '[,=]' | ForEach-Object { $_.Trim('[ "{}]') };
      New-Object PSObject -Property @{
        Name = $projectParts[1];
        File = $projectParts[2];
        Guid = $projectParts[3]
      }
    }

Answer 2

I know that this is maybe already answered question, but I would like to share my approach of reading sln file. Also during run time I am determining if project is Test project or not

function ReadSolutionFile($solutionName)
{
    $startTime = (Get-Date).Millisecond
    Write-Host "---------------Read Start---------------" 
    $solutionProjects = @()

    dotnet  sln "$solutionName.sln" list | ForEach-Object{     
        if($_  -Match ".csproj" )
        {
            #$projData = ($projectString -split '\\')

            $proj = New-Object PSObject -Property @{

                Project = [string]$_;
                IsTestProject =   If ([string]$_ -Match "test") {$True} Else {$False}  
            }

            $solutionProjects += $proj

        }
    }

    Write-Host "---------------Read finish---------------" 
    $solutionProjects

    $finishTime = (Get-Date).Millisecond
    Write-Host "Script run time: $($finishTime-$startTime) mil" 
}

Hope this will be helpfull.

Answer 3

Currently you can use Package Manager Console in VS to obtain that info. Use powershell Get-Project command

Get-Project -All

Answer 4

You can use the EnvDTE.Solution.Projects object to programmatically get access to the projects in a solution.

One gotcha though is that if you have any SolutionFolders in your solution, any projects in these folders are not shown in the above collection.

I've written an article including a code sample on how to get all projects regardless of any solutionfolders

Answer 5

    var Content = File.ReadAllText(SlnPath);
    Regex projReg = new Regex(
        "Project\\(\"\\{[\\w-]*\\}\"\\) = \"([\\w _]*.*)\", \"(.*\\.(cs|vcx|vb)proj)\""
        , RegexOptions.Compiled);
    var matches = projReg.Matches(Content).Cast<Match>();
    var Projects = matches.Select(x => x.Groups[2].Value).ToList();
    for (int i = 0; i < Projects.Count; ++i)
    {
        if (!Path.IsPathRooted(Projects[i]))
            Projects[i] = Path.Combine(Path.GetDirectoryName(SlnPath),
                Projects[i]);
        Projects[i] = Path.GetFullPath(Projects[i]);
    }

Edit: Amended the regex to include the ".*" as per the comment by Kumar Vaibhav

Answer 6

There's a really elegant solution here: Parsing Visual Studio Solution files

The answer by John Leidegren involves wrapping the internal Microsoft.Build.Construction.SolutionParser class.
