잘 작동했지만 더 이상 작동하지 않는 웹 응용 프로그램이 있습니다. 그것은 내 개발 컴퓨터 (로컬 데이터베이스에 연결)에서 작동하지만 프로덕션에서는 작동하지 않습니다. 따라서 개발 컴퓨터에서 프로덕션 데이터베이스에 연결 문자열을 변경하고 오류 : 시퀀스에 둘 이상의 요소가 들어 있습니다.웹 응용 프로그램 오류 : 시퀀스에 둘 이상의 요소가 포함되어 있습니다.
저는 데이터베이스와 관련이 있어야한다고 생각하지만, 그것이 무엇인지 알아내는 방법을 모릅니다. 거의 천 개의 데이터 행이 있습니다.
다음은 데이터를 가져 오는 linq 문입니다. 이 문제를 어떻게 해결할 수 있을지에 대한 아이디어가 있습니까?
protected void lnqItems_Selecting(object sender, LinqDataSourceSelectEventArgs e)
{
DocksideValidationDataContext db = new DocksideValidationDataContext();
DateTime startDate = (radStartDate.SelectedDate.HasValue)
? radStartDate.SelectedDate.Value
: DateTime.Parse("1/1/1900");
DateTime endDate = (radEndDate.SelectedDate.HasValue)
? radEndDate.SelectedDate.Value
: DateTime.Parse("1/1/2500");
int prevalNum = (txtSummaryFormNumber.Text.Trim() == "")
? -1
: Convert.ToInt32(txtSummaryFormNumber.Text.Trim());
e.Result = (from x in db.SummaryForms
where (x.SummaryFormId == prevalNum
|| (prevalNum == -1)
&& (x.SampleDate >= startDate.Date)
&& (x.SampleDate <= endDate.Date)
&& (x.StateId == Convert.ToInt32(ddlState.SelectedValue)))
orderby (x.SampleDate) descending
select x).AsEnumerable()
.Select(x => new
{
x.SummaryFormId,
x.SampleDate,
DockName = x.Dock.Code + " " + x.Dock.Name,
Status = GetStatus(x),
Color = GetStatusColor(GetStatus(x))
})
.Where(x => ((prevalNum != -1
|| cboFilter.Text == "All")
|| (x.Status == cboFilter.Text)));
}

에서덕분에 아니, 나에게 발생하지만, 나는 그것이 유용하다고 생각하지 않았다. 여기있다 :
