錯誤：當我選擇日期時轉換日期和/或時間從字符串轉換失敗？

Question

我有這個gridview的，我用的SqlDataSource

這是我的選擇命令，

<asp:SqlDataSource ID="SqlDataSource1" runat="server" 
    ConnectionString="<%$ ConnectionStrings:TAXIConnectionString %>" 
    SelectCommand="SELECT [TripId] FROM [BookingMaster] 
        WHERE(([PickupLocation] = @PickupLocation or @PickupLocation is null) 
        AND ([DestinationLocation] = @DestinationLocation 
        or @DestinationLocation is null) 
        AND ([Status] = @Status or @Status is null) 
        AND (cast([PickupDateTime] as date) = @PickupDateTime 
        or @PickupDateTime is null))" 
    CancelSelectOnNullParameter="False"> 
     <SelectParameters> 
      <asp:ControlParameter ControlID="ddPickup" Name="PickupLocation" 
        PropertyName="SelectedValue" Type="String" 
        ConvertEmptyStringToNull="true" /> 
      <asp:ControlParameter ControlID="ddDestination" Name="DestinationLocation" 
       PropertyName="SelectedValue" Type="String" 
       ConvertEmptyStringToNull="true" /> 
      <asp:ControlParameter ControlID="ddStatus" Name="Status" 
       PropertyName="SelectedValue" Type="String" 
       ConvertEmptyStringToNull="true" /> 
      <asp:ControlParameter ControlID="txtBookingDate" Name="PickupDateTime" 
       PropertyName="Text" Type="String" ConvertEmptyStringToNull="true" /> 
     </SelectParameters> 
    </asp:SqlDataSource>  

，但正如我13或者之後選擇日期錯誤來了......

Server Error in '/' Application. 

Conversion failed when converting date and/or time from character string. 

這有什麼不對？

聽起來像是本地化問題。我猜你正在輸入dd/mm/yy格式的日期，但是ASP.NET或SQL Server試圖用不變的文化或en-US來分析它們，它們預計爲mm/dd/yy格式。或者相反。將日期傳遞給SQL Server時，最好已使用DateTime.Parse解析它們，或者使用yyyy-MM-dd HH:mm:ss格式將它們作爲字符串傳遞，這是完全明確的。
