如何在asp.net C＃中将数据转换为数组形式？

Question

我有以下代码，数据表仅包含一行。 我希望将所有数据（一行）值保留在数组中。 下面是我的代码：

            SqlCommand cmdp = new SqlCommand("SELECT [1],[2],[3],[4],[5],[6],[7].[8],[9],[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],[20],[21],[22],[23],[24],[25],[26],[27],[28],[29],[30],[31],[32],[33],[34],[35],[36],[37],[38],[39],[40],[41],[42],[43],[44],[45],[46],[47],[48],[49],[50],[51],[52],[53],[54],[55],[56],[57],[58],[59],[60],[61],[62],[63],[64],[65],[66],[67],[68],[69],[70],[71],[72],[73],[74],[75],[76],[77],[78] from [Seatlist] where (([FlightNo] = @FN) AND ([Origin] = @Ori) AND ([Destination] = @Des) AND ([DepartureTimeDay] = @Dep) AND ( [DepartureTimeMonths] = @Dem) AND ( [DepartureTimeYears] = @Dey) AND ( [DepartureTime] = @Det))", con);
            cmdp.Parameters.AddWithValue("@Seatlist", SeatNo.Text);
            cmdp.Parameters.AddWithValue("@FN", FlightNo.Text);
            cmdp.Parameters.AddWithValue("@Ori", Origin.Text);
            cmdp.Parameters.AddWithValue("@Des", Destination.Text);
            cmdp.Parameters.AddWithValue("@Dep", DepartDay.Text);
            cmdp.Parameters.AddWithValue("@Dem", DepartMonth.Text);
            cmdp.Parameters.AddWithValue("@Dey", DepartureTimeYears.Text);
            cmdp.Parameters.AddWithValue("@Det", DepartureTime.Text);
            DataTable dtable = new DataTable();
            dtable.Load(cmdp.ExecuteReader());
            DataRow[] array = dtable.AsEnumerable().Take(1).ToArray();
            object[] array1 = array[0].ItemArray;
            int[] array2 = Array.ConvertAll(array1, (p => Convert.ToInt32(p)));

但是我收到以下错误：

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: The multi-part identifier "7.8" could not be bound.

Answer 1

正如@Kami指出的那样，您的代码很好，但是您得到了[7].[8] 而不是[7],[8] 66 [7],[8] -73中的[7],[8]

Answer 2

现在应该可以正常工作了...

 SqlCommand cmdp = new SqlCommand("SELECT [1],[2],[3],[4],[5],[6],[7],[8],[9],[10],[11],[12],[13],[14],[15],[16],[17],[18],[19],[20],[21],[22],[23],[24],[25],[26],[27],[28],[29],[30],[31],[32],[33],[34],[35],[36],[37],[38],[39],[40],[41],[42],[43],[44],[45],[46],[47],[48],[49],[50],[51],[52],[53],[54],[55],[56],[57],[58],[59],[60],[61],[62],[63],[64],[65],[66],[67],[68],[69],[70],[71],[72],[73],[74],[75],[76],[77],[78] from [Seatlist] where (([FlightNo] = @FN) AND ([Origin] = @Ori) AND ([Destination] = @Des) AND ([DepartureTimeDay] = @Dep) AND ( [DepartureTimeMonths] = @Dem) AND ( [DepartureTimeYears] = @Dey) AND ( [DepartureTime] = @Det))", con);
                cmdp.Parameters.AddWithValue("@Seatlist", SeatNo.Text);
                cmdp.Parameters.AddWithValue("@FN", FlightNo.Text);
                cmdp.Parameters.AddWithValue("@Ori", Origin.Text);
                cmdp.Parameters.AddWithValue("@Des", Destination.Text);
                cmdp.Parameters.AddWithValue("@Dep", DepartDay.Text);
                cmdp.Parameters.AddWithValue("@Dem", DepartMonth.Text);
                cmdp.Parameters.AddWithValue("@Dey", DepartureTimeYears.Text);
                cmdp.Parameters.AddWithValue("@Det", DepartureTime.Text);
                DataTable dtable = new DataTable();
                dtable.Load(cmdp.ExecuteReader());
                DataRow[] array = dtable.AsEnumerable().Take(1).ToArray();
                object[] array1 = array[0].ItemArray;
                int[] array2 = Array.ConvertAll(array1, (p => Convert.ToInt32(p)));
