What API can be used to read OAB Files?

I have OAB file with me.Now i want to programatically read it's content using c#. Can anyone suggest me some APIs which can be used to read OAB files. And related information of them.

Note: Not reading OAB file form Outlook or Exchange Server (I don't want to read OAB from Exchange or Outlook.)

Explanation:

I am manually copying this file from exchange server on my PC.And now i want to read this OAB (offline Address Book). I don't want my applica开发者_开发技巧tion to read OAB files from Exchange or Outlook. I want my application to just allow user to browse OAB file saved on his machine and now read this file.

Hope now it is clear :(

I'm not aware of any API doing this, but you can write your own interface using the Microsoft specification for OAB files.
