小编use*_*269的帖子

我尝试了很多不同的方法并查看了不同的帖子,但仍未找到这种审核方式的解决方案.下面是我的DBContext模板文件.我通过添加OnContextCreated()partial方法来定制它,并将SavingChanges事件分配给我的OnSavingChanges事件处理程序.

namespace ARSystem.Models
{
    public partial class ARSEntities : ObjectContext
    {
        public ARSEntities()

        public void OnSavingChanges(object sender, EventArgs e)
        {
            IEnumerable<ObjectStateEntry> changes = this.ObjectStateManager.GetObjectStateEntries(EntityState.Added | EntityState.Deleted | EntityState.Modified);
            foreach (ObjectStateEntry stateEntryEntity …
