1.在WebService1.asmx页面写两个方法，如下：
[WebMethod]
public List<Model.T_News1> GetProvince(int pagesize,int pageindex)
{
BLL.T_News1 bnews = new BLL.T_News1();
DataTable dt = bnews.GetListTable(pagesize,pageindex);
List<Model.T_News1> list = new List<Model.T_News1>();
int Id;
string newtitle = "";
string newcontent = "";
DateTime creatime;
for (int i = 0; i < dt.Rows.Count; i++)
{
Id = Convert.ToInt32(dt.Rows[i]["Id"]);
newtitle=dt.Rows[i]["NewsTitle"].ToString();
newcontent = dt.Rows[i]["NewsContent"].ToString();
//creatime = Convert.ToDateTime(dt.Rows[i]["CreateTime"]);
creatime = Convert.ToDateTime(dt.Rows[i]["CreateTime"]).;
Model.T_News1 news = new Model.T_News1()
{
Id = Id,
NewsTitle = newtitle,
NewsContent = newcontent,
CreateTime = creatime
};
list.Add(news);
}
return list;
}
[WebMethod]
public int GetListPageindex(int pagesize)
{
BLL.T_News1 bnews = new BLL.T_News1();
int totalcount = bnews.GetRecordCount("");
if (totalcount % pagesize == 0)
{
return totalcount / pagesize;
}
else
{
return totalcount / pagesize + 1;
}
}
2.在三层架构的BLL层，写上下面这句代码
public DataTable GetListTable(int pagesize,int pageindex)
{
return dal.GetListTable(pagesize,pageindex);
}
3.在三层架构的DAL层，写上下面的代码
public DataTable GetListTable(int pagesize,int pageindex)
{
sqlParameter[] parameter =
{
new sqlParameter("@pagesize",sqlDbType.Int),
new sqlParameter("@pageindex",sqlDbType.Int)
};
parameter[0].Value = pagesize;
parameter[1].Value = pageindex;
return DbHelpersql.RunProcedureDataTable("pro_fenye",parameter);
}
