How do I delete multiple rows in Entity Framework (without foreach)

using (var context = new DatabaseEntities())
{
    context.ExecuteStoreCommand("DELETE FROM YOURTABLE WHERE CustomerID = {0}", customerId);
}

Addition: To support list of ids you can write

var listOfIds = String.Join(',',customerIds.Select(id => $"'{id}'").ToList());
var sql= $@"DELETE  [YOURTABLE] WHERE CustomerID in ({listOfIds})";

Note: if CustomerID Is a string, you should double-check for potential SQL injection risks, for integer CustomerID it’s safe

EntityFramework 6 has made this a bit easier with .RemoveRange().

Example:

db.People.RemoveRange(db.People.Where(x => x.State == "CA"));
db.SaveChanges();

Warning! Do not use this on large datasets!

EF pulls all the data into memory, THEN deletes it. For smaller data sets this might not be an issue but generally avoid this style of delete unless you can guarantee you are only doing very small changes.

You could easily run your process out of memory while EF happily pulls in all the data you specified just to delete it.
