WinForm应用程序框架设计之WinAction（删除数据）

我们来先看看WinAction的删除数据的流程：

具体的参考代码：

        public virtual void DeleteEntity(object entity, object caller, object sender, EventArgs e)
        {
            if (caller is IDataListView)
            {
                IDataListView listForm = caller as IDataListView;
                if (null == listForm.DataList || (listForm.DataList is ICollection && (listForm.DataList as ICollection).Count == 0))
                    return;
            }
            if (MessageBox.Show("确实要删除当前记录？", "提示", MessageBoxButtons.YesNo, MessageBoxIcon.Question) == DialogResult.No)
                return;
            //判断当前删除的是否是新增的记录。(如果是新增的那条，其id为-1)
            if (entity is Entity && (entity as Entity).IsNewEntity)
            {
                Form eForm = CallEditForm(caller);
                if (eForm.Visible)
                    eForm.Close();
                return;
            }
            useBll.Delete((T)entity);
            if (updateFreshByDB && caller is IDataListView && (caller as IDataListView).RefreshEntityList != null)
                (caller as IDataListView).RefreshEntityList((caller as IDataListView).SearchEntity, caller, sender, e);
        }
