Specified cast is not valid. Error

Hi,

I have an data set that I retrieve corectly from a table(dealers).
Then I try to cast this dataset to as type delaserfl that is defined in an xsd file ( I obtained that file by drag and drop the table from sql to DealerFl.xsd file)

All this is done into this function
************************************
Public Function GetDealerInfo(ByVal dlr As String, ByVal connectionString As String) As DealerFl
Dim strSQL As String
Dim conn As Data.SqlClient.SqlConnection = New Data.SqlClient.SqlConnection(connectionString)

conn.Open()
strSQL = " SELECT * "
strSQL &= " FROM dealer.dbo.DealerFlags d "
strSQL &= " WHERE dlrAct = " & dlr.ToString

' Call ExecuteXmlReader static method of SqlHelper class that returns an XmlReader

' We pass in an open database connection object, command type, and command text

Dim ds As New DataSet()
Dim dfl As New DealerFl()
ds = SqlHelper.ExecuteDataset(conn, CommandType.Text, strSQL)

' I get the error at the next instruction

dfl = CType(ds, DealerFl)
Return dfl


End Function
****************************************

What may be wrong?

Thank you,
