Open special section of a local HTML file in default browser

I want to open the documentation, which is stored in a single local html file, when the user clicks on certain wpf controls. Normally, the file can be navigated using HTML sections, and links like file:///C:/Users/uname/Desktop/Tool/DOCUMENTATION.html#section work (page is automatically scrolled so the section is in view) when I copy them into the address field, but when I try to open the browser by starting a new process using that same URL, the section at the end always gets removed and the page is shown from the top. This is the code I use to open the browser:

Process.Start(new ProcessStartInfo
            {
                FileName = "cmd.exe",
                Arguments = "/C start " + "file://" + AppDomain.CurrentDomain.BaseDirectory + "DOCUMENTATION.html" + "#" + section,
                WindowStyle = ProcessWindowStyle.Hidden,
                CreateNoWindow = true
            });

I first tried to open the file directly as a new process (Process.Start("path\to\file.html")) but I obviously cannot auto-navigate to sections that way.

Is there any way to achieve this "focus" on a certain section?

>Solution :

Back in 2010, this question was answered as follows (in VisualBasic):

    Dim BrowserRegistryString As String = My.Computer.Registry.ClassesRoot.OpenSubKey("\http\shell\open\command\").GetValue("").ToString
    Dim DefaultBrowserPath As String = System.Text.RegularExpressions.Regex.Match(BrowserRegistryString, "(\"".*?\"")").Captures(0).ToString
    Dim LocalURL As String = "file:///C:/users/matt/desktop/page.htm#test"
    Process.Start(DefaultBrowserPath, LocalURL)

Try to migrate that to C#.

The cmd shell does not pass the #test anchor tag, because the tag does not belong to the object to be started by the shell. Therefore, you probably have to explicitely start a browser. Either you encode your favorite browser, or you extract the default browser from the registry as shown in the example.
