Which is the good way to update object in EF6
- by TrieuH
I have searched and find 2 way to update object in EF
var attachedEntity = _context.EntityClasses.Local.First(t => t.Id == entity.Id);
//We have it in the context, need to update.
if (attachedEntity != null)
{
var attachedEntry = _context.Entry(attachedEntity);
attachedEntry.CurrentValues.SetValues(entity);
}
else
{
////If it's not found locally, we can attach it by setting state to modified.
////This would result in a SQL update statement for all fields
////when SaveChanges is called.
var entry = _context.Entry(entity);
entry.State = EntityState.Modified;
}
_context.SaveChanges();
And other way is seem more easy
var entity = _context.EntityClasses.FirstOrDefault(t => t.Id == entity.Id);
_context.Entry(entity ).EntityState.Modified
_context.SaveChanges();
What is best way to update object?
NOTE: the performence is importance with me
