WCFServices

Hi,

I am trying to create a WCF web service and it is working fine while passing single parameter. But not sure how to loop through multiple records.

For example i am able to send the parameter as 1 and the return value is working perfectly fine. But when i send multiple input parameters like 1,2 i am getting the error. Please find the code i am using. It would be helpful somebody could help me on this.


using (DbDataReader reader = command.ExecuteReader())
{

while (reader.Read())
{

Testdata.Id= Convert.ToInt32(reader[0]);
Testdata.prd = Convert.ToInt32(reader[1]);
Testdata.fran = Fra.ToString();
Testdata.TP = Tf.ToString();

}
}
