UnitOfWork CommitChanges 不编辑数据库行

Question

所以我正在使用 UnitOfWork 将对象保存到数据库中。这非常有效。但是，当我尝试编辑对象并再次保存时，没有任何更改写入数据库。

这是用于保存的片段：

this.uow = new UnitOfWork();
this.job = new Job(uow);

using (UnitOfWork u = new UnitOfWork())
            {
                job.Truck = cboTrucks.SelectedItem.ToString();
                job.Driver = cboDriver.SelectedItem.ToString();
                job.Load = txtLoad.Text;
                job.Comment = txtComment.Text;
                job.FileOk = chkFile.Checked;
                job.Notified = chkNotified.Checked;
                job.JobDate = dteJobDate.DateTime;

                u.CommitChanges();
            }

Answer 1

我终于让它工作了这是我改变的:

之前：

this.uow = new UnitOfWork();
this.job = new Job(uow);

之后：

this.uow = new UnitOfWork();
this.job = new XPQuery<TIS.Model.Internal.Job>(uow).Where(q => q.Id == job.Id).FirstOrDefault();
