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

    var Content = File.ReadAllText(SlnPath);
    Regex projReg = new Regex(
        "Project\\(\"\\{[\\w-]*\\}\"\\) = \"([\\w _]*.*)\", \"(.*\\.(cs|vcx|vb)proj)\""
        , RegexOptions.Compiled);
    var matches = projReg.Matches(Content).Cast();
    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
