Content Type Id for Image, Audio and Video

After debugging I have found the Content Type Ids for Image, Audio and Video in the assets library. These content type ids are not present in SPBuiltInContentTypeId.

public class SPBuiltInContentTypeIdExtension
{
  public static SPContentTypeId Video =
    new SPContentTypeId
     ("0x0101009148F5A04DDD49CBA7127AADA5FB792B00291D173ECE694D56B19D111489C4369D");
  public static SPContentTypeId Audio =
    new SPContentTypeId
      ("0x0101009148F5A04DDD49CBA7127AADA5FB792B006973ACD696DC4858A76371B2FB2F439A");
  public static SPContentTypeId Image =
    new SPContentTypeId
      ("0x0101009148F5A04DDD49CBA7127AADA5FB792B00AADE34325A8B49CDA8BB4DB53328F214");
}

These three asset content types inherit from Document CT (“0x0101”) and have “0x0101009148F5A04DDD49CBA7127AADA5FB792B” in common, which is the content type id for multimedia content type. So if you want to check if it is a multimedia, use this id. You can see the content type id when you go to Site Actions - Site Settings - Content Types. Click on a content type you interested in. In the address bar of your browser find ?ctype=.

/_layouts/ManageContentType.aspx?
ctype=0x0101009148F5A04DDD49CBA7127AADA5FB792B00AADE34325A8B49CDA8BB4DB53328F214

Eller i koden så kan du göra så här:

var id = properties.Web.AvailableContentTypes
   .BestMatch(properties.ListItem.ContentTypeId);

Enjoy.

Although not in SPBuiltInContentTypeId, they are in Microsoft.SharePoint.Publishing.ContentTypeId. So an alternative is to add a reference to Microsoft.SharePoint.Publishing and then use ContentTypeId.Audio | ContentTypeId.Image | ContentTypeId.Video.

It was really nice, thanks for your finding!
