以下包含了这两种不同属性的用法：
foreach (DataRow dr in dataset.Tables[0].Rows)
{
if (i != 0 && lujing!="")
{
DataTable dt = new DataTable();
dt = new BLL.production().GetList_pro(" production_id=" + dr["Column1"]).Tables[0];
int n = int.Parse(dt.Rows.Count.ToString());
if (n == 0)
{
model.channel_id = 20;
model.category_id = 83;
model.production_id = int.Parse(dr["Column1"].ToString());
model.pmzc = dr["Column2"].ToString();
model.title1 = dr["Column3"].ToString();
model.author = dr["Column4"].ToString();
model.img_url1 = lujing + dr["Column5"].ToString();
model.size = dr["Column6"].ToString();
model.creation_year = dr["Column7"].ToString();
model.judge = dr["Column8"].ToString();
if (!string.IsNullOrEmpty(dr["Column10"].ToString()))
{
model.explain_1 = dr["Column10"].ToString();
}
model.explain_2 = dr["Column11"].ToString();
model.sort_id = 99;
if (bll.Add(model) < 1)
{
}
}
else {
foreach (DataRow item in dt.Rows)
{
Model.production model_1 = bll.GetModel(int.Parse(item["id"].ToString()));
model_1.price_1 = dr["Column9"].ToString();
if (bll.Update(model_1))
{
}
}
}
}
i++;
}
