Adding The Parameters Dynamicaly To SP

In our website we have created the reportengine which passes the parameters dynamicaly means whatever parameters are provided in Stored procedure is automaticaly binded to grid from where values are passed to sp as follows
.Actualy this code is written by some other developer
If Not ParameterTable Is Nothing Then
   RecordCount = ParameterTable.Rows.Count
         If RecordCount >= 1 Then
        For Index = 0 to (RecordCount - 1)
       ParameterRow = ParameterTable.Rows(Index)
    Select Case ParameterRow(1)
             Case "231"
              RecordType = "SQlDbType.NVarChar"
       Case "60"
        RecordType = "SQlDbType.Money"
             Case "61"
              RecordType = "SQlDbType.DateTime"
       Case "62"
        RecordType = "SQlDbType.Int"
             Case "59"
              RecordType = "SQlDbType.Float"
       Case "104"
        RecordType = "SQlDbType.Bit"
     Case Else
                 RecordType = "SQlDbType.Int"
                
          End Select
       myCommand.Parameters.Add(ParameterRow(0), RecordType).Value = (ParameterRow(2))
