Delete Virtual Directory and related Folder

Seems useful because till date i was using a vbscript file to do this from a cscript console.. I am not sure if you had a question.. seems like you are asking how to know if the propertycollection has a property or not?

The virtual directory that is created by Visual Studio 2003, is lit bit different than the virtual directory that is made as Web Sharing from Folder Properties.
I found one useful facts after I have checked the differences between two types of virtual directories using metaedit2.2. If the vd is created by VS2003, the data of "keyType" Key of this virtual directory will be "IIsWebDirectory". Likewise, If the vd is made as Web Sharing, the data of "keyType" Key of this virtual directory will be "IIsWebVirtualDir". So, we can know whether we need to check the path property or not by checking the data of "KeyType".

Deleting Virtual Directory...

System.DirectoryServices.DirectoryEntry iISAdmin = new System.DirectoryServices.DirectoryEntry("IIS://" + sWebSite + "/W3SVC/1/Root");

string sWebPath = iISAdmin.Properties["Path"].Value.ToString();

//If the virtual directory already exists then delete it
foreach(System.DirectoryServices.DirectoryEntry vd in iISAdmin.Children)
{
if(vd.Name==sAppName)
{
sWebPath += "\\" + vd.Name;

if(vd.KeyType == "IIsWebVirtualDir")
sWebPath=vd.Properties["Path"].Value.ToString();

iISAdmin.Invoke("Delete", new string[]{vd.SchemaClassName, sAppName});
System.IO.Directory.Delete(sWebPath);
iISAdmin.CommitChanges();

break;
}
}
