Question

I have list like this:

var list = new List<string>();

This list contains lets say following names: “Ken”, “John”, “Tom”, etc.

I need to add this list to database table which looks like this:

Id          SecondId              Name
1           1                     Ken
2           1                     John
3           2                     Tom

Where SecondId is secondary key and that info i already have. But my question is there a better way of adding all names to the database without iterating through list using foreach loop? Any linq query or some other way or i have to iterate through the list to add them to database one by one?

Answer 1

I don’t think there is a way to add the list as a chunk.
You could use the ForEach extension method on the List like so (assuming you are using a DbContext for database access):

using (var context = new NameContext()) {
    list.ForEach(i => context.Names.Add(new Name(i, SECOND_ID)));
}

You can use the same approach but use you database writing code inside the lambda expression in case you are not using DbContext.
