Listing out all sites and their document roots in .Net

So, I had a problem today that required me to find all document roots for an IIS server which is trivial (open up IIS manager, silly) on a single box. However, in this case the code would run on random boxes and I would never know what was on there.

Below is the solution I came up with is below. Hopefully it will be helpful to someone else.

Note: I had to include System.DirectoryServices into the references and in the using/imports clause.

DirectoryEntry de = new DirectoryEntry();

de.Path = "IIS://LocalHost/W3SVC";

foreach(DirectoryEntry deTmp in de.Children) 
{
  // If the server doesn't have a state it is more 
  // than likely an app pool or something similar so we don't care
  if(deTmp.Properties["ServerState"].Value != null) 
  {
    DirectoryEntry deDocRoot = new DirectoryEntry();
    deDocRoot.Path = "IIS://LocalHost/W3SVC/" + deTmp.Name + "/ROOT";

    if(deDocRoot.Properties["path"].Value != null) 
    {
       string DocRoot = deDocRoot.Properties["path"].Value.ToString();

       // Do whatever you want to with the values now...
    }
  }
}

I hope someone else finds this useful.

Also, the MSDN documentation for these object is here.
