在父项之前删除子实体。 [英] Deleting child entities before the parent.

问题描述

大家好，

我有以下代码删除没有附加子项的父级...

I have the following code which deletes a parent with no children attached...

 using (CounterfeitEntities Deletecontext = new CounterfeitEntities())
            {
                try
                      {
                         
  
                          int IDtoDelete = Convert.ToInt32(counterfeitIDTextBox1.Text);
                          CounterfeitPart deletepartNew = Deletecontext.CounterfeitParts.First(i => i.CounterfeitID == IDtoDelete);
                          //CounterfeitPart deletepartNew = Deletecontext.CounterfeitParts.Include("CounterfeitPartsImage").First(i => i.CounterfeitID == IDtoDelete);
                          Deletecontext.CounterfeitParts.DeleteObject(deletepartNew);
                          Deletecontext.SaveChanges();


                      }
                catch (System.Exception excep)

                      {
                        MessageBox.Show(excep.Message);
                      }


                LoadData();

                System.Windows.MessageBox.Show("Record deleted.", "Information", MessageBoxButton.OK, MessageBoxImage.Information);

            }

当附加子记录时，这会出错。我如何首先删除任何子记录？

This however errors when there are child records attached. How do I first delete any child records?

谢谢，

Dean
