Replacing foreach on a list with LINQ

I'm not sure if this would be desirable, but is there a LINQ "way" of replacing the following:

foreach (var u in users)
    context.Users.Add(u);

with something like

context.Users.Add(....);

Assuming users is type List<User> you just do

users.ForEach(u => context.Users.Add(u));

though you don't need to use LINQ. You could just do

context.Users.AddRange(users);

If Users is a DbSet then you can probably do without looping at all by using AddRange:

context.Users.AddRange(users);

However if you really want to use Linq, then you can also do this:

users.ToList().ForEach(u => context.Users.Add(u));

Or the shorthand version:

users.ToList().ForEach(context.Users.Add);

You don't need LINQ. You need to use AddRange instead of Add:

context.Users.AddRange(users);

Assumption: you're using Entity Framework and Users is of type DbSet<T>
