我想在表格中显示议程" tblAgenda"在这里使用Asp.net是查询:
public static List<int> SelectByYear()
{
DbManager db = new DbManager();
try
{
List<int> list = new List<int>();
var result = from p in db.tblAgenda
group p by p.News.Value.Year
into g
select new { Year = g.Key, Releases = g };
foreach (var obj in result)
{
list.Add(obj.Year);
}
list.Reverse();
return list.ToList<int>();
}
catch
{
return null;
}
finally
{
db.Dispose();
}
}
在这里我打电话给上面的方法:
public partial class edd_Default : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(Request.QueryString["id"]))
{
RecentData();
}
}
}
private void RecentData()
{
List<tblAgenda> agd = new List<tblAgenda>();
StringBuilder sbHeadings = new StringBuilder();
StringBuilder sbData = new StringBuilder();
List<int> list1 = AgendaManager.SelectByYear();
if (list1 != null)
{
List<int> list = list1.Take(3).ToList<int>();
int Row = 0;
string RowCss = "";
foreach (tblAgenda ob in agd)
{
strYears = "";
if (list.Count > 0)

string stryr = strYears;

现在的问题是我在list1中没有得到任何值,我尝试在查询中使用调试器,发现我无法访问&#34; tblAgenda&#34;,它给出的错误是: &#34;由于先前的功能评估超时,因此功能评估被禁用。您必须继续执行以重新启用功能评估&#34;。我搜索了很多,但没有找到任何好的,我的连接字符串是完全正常的,因为所有其他表格工作正常,即使在&#34; tblAgenda&#34;我可以从管理面板存储新议程,但我无法检索前端的议程,这里有什么问题? 感谢。
