ASP.NET DataContext問題

我正在調用DataContext對象的ExecuteQuery方法。我期望每行都有一個字符串和一個整數作爲結果，但是當我運行ToList函數時，我所有的值都是無關緊要的。我所有的結果都應該是不同的字符串和數字。如果我直接運行它，我的查詢運行完美，但ExecuteQuery返回垃圾而不是有效的結果。這可能是什麼原因？ASP.NET DataContext問題

預先感謝您。

編輯：

public function something as List(of Pair(of String, Integer)) 
      Dim c As TTDataContext = ContextFactory.CreateDataContext() 
      Dim startValueLen = CStr(StartValue).Length 
      Dim query As String = "select top " & CStr(Limit) & " case " & 
                    " when WONum like '0000%' then SUBSTRING(WONum, 5, Len(WONum) - 4) " & 
                    " when WONum like '000%' then SUBSTRING(WONum, 4, Len(WONum) - 3) " & 
                    " when WONum like '00%' then SUBSTRING(WONum, 3, Len(WONum) - 2) " & 
                    " when WONum like '0%' then SUBSTRING(WONum, 2, Len(WONum) - 1) " & 
                    " else WONum " & 
                    " end as retVal, " & 
                    " case " & 
                    " when WONum like '0000%' then 1 " & 
                    " when WONum like '000%' then 2 " & 
                    " when WONum like '00%' then 3 " & 
                    " when WONum like '0%' then 4 " & 
                    " else LEN(WONum) " & 
                    " end as retLen " & 
                    " from TblWorkOrder " & 
                    " where CompanyID = " & CStr(CompanyID) & " and LEN(WONum) >= " & CStr(startValueLen) & " and (WONum > '" & CStr(StartValue) & "' or LEN(WONum) > " & CStr(startValueLen) & ") " & 
                    " order by retLen, retVal" 
      Dim temp = c.ExecuteQuery(Of Pair(Of String, Integer))(query) 
      Return temp.ToList 
End Function

也許給我們展示一些代碼？你如何期望我回答這個？ – Pleun

你可以發佈你的代碼嗎？ –

感謝您的評論，我已經發布了一個非常簡單的代碼，因爲我的查詢大約有1500個字符。 –
