How to implement web api by passing array as parameter

Hi,

 

This is my code :

 

[Route("status")]
public Notification UpdateNotificationStatus(int [] NotificationId)
{
throw new NotImplementedException();
} 

 

This is my table :

 

 

 

So when I passing api uri like this : 

/members?notificationid=1,2,3,4 Then update the table
IsRead is true based on by passing NotificationID's.
Using Stored Procedure or Linq to Sql.
Please give me a code for that.

Thank you.
