重载“DeleteEntity”方法未获取“1”参数!!!!!! 
不是说的很清楚吗，deleteＥntity调用的参数不对．
把你的ＤeleteＥntity方法也贴出来看看

Answer 2

DeleteEntity方法public bool DeleteEntity(CollectionMallOrder CollectionMallOrderData, DataTable dtOrderDetail, CollectionMallStock entCollectionMallStock) 
{
  ...........
  ...........
  for(int i=0 ; i< dtOrderDetail.Rows.Count ;i++)
{ 
this.entCollectionMallStock = this.bllCollectionMallStock.GetStockByProductGUID(this.session,dtOrderDetail.Rows[i]["Mall_Product_GUID"].ToString());
this.entCollectionMallStock.MallProductCount= this.entCollectionMallStock.MallProductCount + Convert.ToInt32(dtOrderDetail.Rows[i]["CollectionMallProductCount"].ToString());
this.bllCollectionMallStock.UpdateEntity(this.session,this.entCollectionMallStock);
} if(this.bllCollectionMallOrderDetail.DeleteEntity(this.session,CollectionMallOrderData.Id)==false ||
this.dalCollectionMallOrder.DeleteData(this.session,CollectionMallOrderData)==false )
{
this._ErrorMessage=this.dalCollectionMallOrder.ErrorMessage;
this.transaction.Rollback();
this.session.Close();
return false;
}
else
{
this.transaction.Commit();
this.session.Close();
return true;
}
}在上面的函数里改成entCollectionMallOrder.Id = datalistNavigateOrder.DataKeys[e.Item.ItemIndex].ToString();
this.entCollectionMallOrderDetail.CollectionMallOrder = entCollectionMallOrder;
DataTable dtOrderDetail =new DataTable(); 
entCollectionMallStock.Id = datalistNavigateOrder.DataKeys[e.Item.ItemIndex].ToString();
this.bllCollectionMallOrder.DeleteEntity(entCollectionMallOrder,dtOrderDetail,entCollectionMallStock);
System.Web.UI.Page currentPage= (System.Web.UI.Page)this.Page;
Response.Redirect(currentPage.Request.Url.ToString());
已经是不报错了  能不能用还没测试呢
