asp.net - Can I setup an IIS MIME type in .NET?

Question

Can I setup a custom MIME type through ASP.NET or some .NET code? I need to register the Silverlight XAML and XAP MIME types in IIS 6.

Answer 1

To add to the master mime type list:

using (DirectoryEntry mimeMap = new DirectoryEntry("IIS://Localhost/MimeMap"))
{
    PropertyValueCollection propValues = mimeMap.Properties["MimeMap"];

    IISOle.MimeMapClass newMimeType = new IISOle.MimeMapClass();
    newMimeType.Extension = extension; // string - .xap
    newMimeType.MimeType = mimeType;   // string - application/x-silverlight-app

    propValues.Add(newMimeType);
    mimeMap.CommitChanges();
}

Add a reference to :

'System.DirectoryServices' on the .NET add references tab
'Active DS IIS Namespace Provider' on the COM add references tab.

To configure a mime type for a specific site, change ..

'IIS://Localhost/MimeMap'

to

'IIS://Localhost/W3SVC/[iisnumber]/root'

...replacing '[iisnumber]' with the IISNumber of the website.
