I learned some basic stuff on EF 4.0 and recently upgraded to EF 6.0. I can't seem to get a simple insert working. Has the "ent.AddtoImage()" been deprecated in version 6.0? I searched around but cannot find an answer.
using (evEntities ent = new evEntities())
{
Image insertImg = new Image();
insertImg.TypeID = "a";
ent.AddtoImage(insertImg);
ent.SaveChanges();
}
I get a red squiggly line under AddtoImage ???
Edit: here is an image -
Assuming that Image is an entity generated by EF you can use
ent.Images.Add(insertImg);
in EF6, then the rest of your code.
Yeah.
beacause evEntities is valid only in the scope of the using statement, which is the next block.
As you miss {} - that next blcock is the next statement, which is
Image insertImg = new Image ();
Right after that line, evEntities is disposed and the variable invalid.
Wrap the whole lines after using into curly braces to make them one block.
using (evEntities ent = new evEntities()) {
....rest of your code
}
Try this instead
evEntities.Entry<Image>(ent).State = EntityState.Added;
ent.SaveChanges();
or
evEntities.Set<Image>().Add(ent);
ent.SaveChanges();
