How to retrieve SQL row ID

I have a winforms project where I search for a term that the user enters. Here is the Linq code I am using to search for the word in the database.

            var query = db.PASSWORDINFOs.Where(c => c.Name == term.ToLower()).ToList();

My question is, when the query returns, how can I get the Row ID so I can then use that for updating and deleting of the record without having to query again?

The variable query holds a list of PASSWORDINFOs. In each element of the list you can access the columns of that PASSWORDINFOs instance. So if ID is a member of that object you can get to it by iterating through the list and access it by using the property something like this

foreach( PASSWORDINFOs pi in query )
    Console.WriteLine("ID = " + pi.ID);
