将一个特定列的备用行显示到两个不同的列

Question

我有一个表有字段Empid，RecTime，EmpId，Recdate。

这是代码：  s =“选择e.EmpName，a.EmpId，a.WorkID，a.RecDate，a.RecTime来自HrEmployee e，AtdRecord a a aEmpId = e.EmpId and EmpName ='”＆amp; TextBox1.Text＆amp; “'与'之间的RecDate'＆amp; TextBox2.Text＆amp; “'和'”＆amp; TextBox3.Text＆amp; “'”

    cmd = New SqlCommand(s, conn)
    cmd.ExecuteNonQuery()
    da = New SqlDataAdapter(s, conn)
    'ds = New DataSet 'da.Fill(ds)
    dt = New DataTable()
    da.Fill(dt)
    dc1 = New DataColumn("InTime")  ' make column InTime and OutTime
    dc2 = New DataColumn("OutTime")
    dt.Columns.Add(dc1)
    dt.Columns.Add(dc2)
    'For entering data from database col to datatable (Intime,Outtime)
    For Each dr In dt.Rows
        i = 4
        mystring = dr(i)

        timestring = dt.Rows.IndexOf(dr)
        If timestring Mod 2 = 0 Then

            j = 5

            dr(j) = mystring
        Else
            k = 6
            dr("OutTime") = mystring
        End If
    Next

    For Each col In dt.Columns
        bfield = New BoundField
        bfield.DataField = col.ColumnName
        bfield.HeaderText = col.ColumnName
        'GridView1.Columns.Add(bfield)
    Next
    GridView1.DataSource = dt
    GridView1.DataBind()
    conn.Close()

我想知道如何从RecTime中获取此场景中的值：

InTime    Outtime    
8             9
1:30          2:45

当RecTime：

    8
    9
    1:30
    2:45
