How to determine record id in asp.net by text field db.Mods.Find(id) doesn't work?

Question

ASP.NET

It is necessary to find the record id by some method to EF, by another text field, how to do this?

Answer 1

If I understand correctly, you want to get a specific entry or its IDs?
If the field is not unique, then you need to take into account that there can be several such records
If the field is unique
Or if this field is a foreign key, then you can

var itemId = db.Mods.Single(m=>m.SomeField==model.SomeField).Select(m=>m.Id);
