Calling IIsWebServer.Status via ADSI and C#

09 November 2005

The IIS ADSI Provider reference (incorrectly) states that IIsWebServer.Status is a method call, but the following code snippet fails with HRESULT 0x80020003.

DirectoryEntry ent = 
                 new DirectoryEntry("IIS://localhost/W3SVC/1");
// next call throws 
// System.Runtime.InteropServices.COMException (0x80020003): Member not found.
int status  = (int) ent.Invoke("Status",null);

It happens that IIsWebServer.Status is actually a property and the proper calling mechanism would be :


DirectoryEntry ent = 
                 new DirectoryEntry("IIS://localhost/W3SVC/1");
Object ads = ent.NativeObject; Type type = ads.GetType();
int status  = (int)type.InvokeMember("Status", 
                                       BindingFlags.GetProperty,
                                       null, ads, null);
