The application downloads some files. My table contains a documentID which is the primary key, the document name,file size and download completed time. How to update the table?

Answer 1

There are basically 2 ways how you can achieve this.

1. Either you can create the database and your tables structure earlier and place database file in your project under resources and on first launch of application you can copy that database to isolated storage.

2. Secondly define your table structures as classes and create the database and tables at first launch of your application.

You can create your Datacontext class deriving from the default Datacontext class so that you can save and get data through LINQ queries.

Hope this helps.
