I am trying to create a query for entity framework that will allow me to take a list of ids and update a field associated with them.
Example in SQL:
UPDATE Friends
SET msgSentBy = '1234'
WHERE id IN (1, 2, 3, 4)
How do I convert the above into entity framework?
something like below
var idList=new int[]{1, 2, 3, 4};
using (var db=new SomeDatabaseContext())
{
var friends= db.Friends.Where(f=>idList.Contains(f.ID)).ToList();
friends.ForEach(a=>a.msgSentBy='1234');
db.SaveChanges();
}
you can update multiple fields as below
friends.ForEach(a =>
{
a.property1 = value1;
a.property2 = value2;
});
