Answer 1

int.Parse DateTime.Parse 很危险啊

Answer 2

到最后
catch (Exception ex)
  {
  log.Error(ex.Message);
  }
ex这个地方报错

Answer 3

log.Error(ex.Message);
换成
log.Error(ex.ToString());

Answer 4

int.Parse DateTime.Parse这个地方有什么问题不？

Answer 5

this.hfParent.Value
txtorderid.Text
this.txtprice
txtbegintime.Text
lanmu.SelectedValue
ID
出错时你检查下上面这些的值分别是什么，贴上来最好

Answer 6

log.Error(ex.Message);
换成
log.Error(ex.ToString());
也还是不行

Answer 7

一步步执行，看看是那句代码报错，然后跳到错误catch中了
你代码中确实用了很多 Parse 相关的，这个你要不做判断，最有可能出错的就是他，当数据不能被转换为目标类型是就会出错了

Answer 8

this.hfParent.Value=1
txtorderid.Text=999
this.txtprice=1800
txtbegintime.Text=2006-12-8 0:00:00
lanmu.SelectedValu  没有获取到值

Answer 9

这段代码没有执行就直接跳到catch里面，上面的代码没有报错
if (((Button)sender).Text == "保存")
                    {
                        string savePath = "Product/" + GetClassDirectory(parentID.ToString()) + "/" + DirFile.GetDateDir() + "/";
                        string fileName = DirFile.GetDateFile();
                        string fileEXName = ".html";
                        productenti.SavePath = savePath;
                        productenti.FileName = fileName;
                        productenti.FileExName = fileEXName;
                        if (Tab_Product.Add(productenti) == 1)
                        {
                            CreateHmtl(productenti);
                            PageInfo("添加成功", "Product_List.aspx");
                        }
                        else
                        {
                            PageInfo("添加失败", "Product_Add.aspx");
                        }
                    }
                    else if (((Button)sender).Text == "保存修改")
                    {
                        string ID = Request.QueryString["ID"];
                        productenti.SavePath = ViewState["SavePath"].ToString();
                        productenti.FileName = ViewState["FileName"].ToString();
                        productenti.FileExName = ViewState["FileExName"].ToString();
                        if (ID == null || ID.Equals(""))
                        {
                            PageInfo("参数错误", "Product_List.aspx");
                        }
                        else
                        {
                            productenti.ID = int.Parse(ID);
                            if (Tab_Product.Edit(productenti) == 1)
                            {
                                CreateHmtl(productenti);
                                PageInfo("修改成功", "Product_List.aspx");
                            }
                            else
                            {
                                PageInfo("修改失败", "Product_List.aspx");
                            }
                        }
                    }

Answer 10

你先把方法里的 try catch 去掉，然后再调试，等到报错，看出在哪行上
