Get Autogenerated Guid- MVC

Does anyone happen to know if there is a way in the Entity Framework to return me the Guid of 开发者_运维百科a just inserted row, assume the column is an guid which is auto Generated.

I am using MVC with Entity Framework. I am using Repository Method ADD(), the return type of the method is void.

Any one knows?

StewieFG,

On adding the item, and hitting SaveChanges(), your object should now be populated with the value of the autogenrated column. Consider the example below:

[HttpPost]
public ActionResult Create(MyEditViewModel viewModel)
{
    if (ModelState.IsValid) {
        _myService.Insert(viewModel.Entity);
        _myService.SaveChanges();
        // we can query the column value for the autogenerated value now
        // i.e. viewModel.Entity.GuidIDColumn value etc..
        return this.RedirectToAction(x => x.Index());
    } else {
        PopulateViewModel(viewModel);
        return View(viewModel);
    }
}

hope this helps
