The MySqlParameterCollection only accepts non-null MySqlParameter type objects. (no replies)

Hi All,

I am trying to insert some value in my table with using Web Service on .net.

If I publish web site and host it IIS i get this error when i use web service.

The MySqlParameterCollection only accepts non-null MySqlParameter type objects.
Parameter name: value

If I build and debug my code there is non null parameter even I see values in my table. what is going on? i didnt understand anything. Is this related with IIS?

Please, I know I have not non-null value..All Values have their value!! So, Can Someone give me some idea?? What is happening here??
