How to get media library extension and mime type programmatically in Sitecore

One of my colleague asked me that how to get extension of uploaded file in Sitecore media library programmatically?

Here are different pointers which may be useful for you while working with media library 

·         You can get media library item in LinkField type from Sitecore.Data.Fields namespace.

·         LinkField.TargetItem -> gives reference of media library item.

·         Sitecore.Resources.Media.MediaManager.GetMediaUrl(linkField.TargetItem) -> Return media links

·         By default, link extension is “.ashx”

·         Get the extension and mime type of media library item by using below code

//Return extension like gif

string mediaItemExtension = linkField.TargetItem.Fields["Extension"].Value;

//Return mime type like image/gif

string mediaItemMimeType = linkField.TargetItem.Fields["Mime Type"].Value;

·         You can also view both of these fields in Sitecore content tree as

Media item

  

·         Let me cover one important entry in web.config file for media library item extension.

<!--  MEDIA - USE FILE EXTENSION IN ITEM NAMES

      Indicating whether to include a file extension when generating an item name from a file name.

      Default value: "false"

-->

<setting name="Media.IncludeExtensionsInItemNames" value="false"/>

·         As comments above explain that if you want to include extension in media item name then set this property as true and when you upload any file in media library for example “1.JPG” then after uploading, Sitecore give its name as “1 jpg” as shown in below image. By default this value is false and for uploading “1.JPG”, Sitecore name it as “1” as shown in first image.
