Network Programming in .NET

Using ADSI, once you have a DirectoryEntry object for a given website using

var root = new DirectoryEntry(“IIS://localhost/W3SVC”);
foreach (DirectoryEntry e in root.Children)
{
if (e.SchemaClassName != “IIsWebServer”) continue;

// e now represents a website in IIS

}

You can start and stop it using

Entry.Invoke(“start”);

Entry.Invoke(“stop”);

However, these commands run asynchronously, and you need to poll on the value

Entry.Invoke(“Get”, “ServerState”)

Where 4 is stopped and 2 is started. However, those using IISAdmin.net will find that this value never changes, meaning that it is impossible to tell when the website has actually changed state. Therefore, my fix was calling:

Entry.RefreshCache();

Prior to calling Invoke/Get
