請你能幫我按第二列降序排序嗎?按降序排列二維數組vb.net
Dim ds As New DataSet()
conn.Open()
techSpeciality = LB_techFaultType.Text
techZone = LB_TechZone.Text
Dim strSQL As String = "SELECT Tech_ID, Last_Zone FROM Technician_List WHERE Availability=TRUE AND Speciality='" & techSpeciality & "' AND Last_Zone='" & techZone & "'"
Dim da As New OleDbDataAdapter(strSQL, conn)
da.Fill(ds)
'2D array
Dim values(ds.Tables(0).Rows.Count - 1, 2) As Integer
'for loop between 0 and all available technicians
For value As Integer = 0 To ds.Tables(0).Rows.Count - 1
'Tech_ID column
values(value, 0) = ds.Tables(0).Rows(value).Item(0).value()
'Zone column, converts negative value to a positive and minus' the selected techZone
Math.Abs(values(value, 1) = techZone - ds.Tables(0).Rows(value).Item(1).value())
