Just getting to grips with Entity Framework and I can save, add, delete etc

  • 0

Just getting to grips with Entity Framework and I can save, add, delete etc a single entity like so:

db.Entry(client).State = EntityState.Modified;
db.SaveChanges();

My question is if I wanted to change several records how should I do this, for example I want to select all Jobs with a Type of ‘new’ and set the Type to ‘complete’. I can select all the jobs easily enough with Linq but do I have to loop through, change them, set the state to modified, save changes, next one etc? I’m sure there is a straightforward way that I just don’t know about or managed to find yet.

    Are you sure you need to set the EntityState? SaveChanges will DetectChanges before saving. You can’t update multiple records at once as you are requesting, but you can loop through, update the value and call save changes after the loop. This will cause 1 connection to the database where all of your updated records will be saved at once.
