The SqlParameterCollection only accepts non-null SqlParameter type objects, not MySqlParameter objects.

Question

Hi,

I have created a method that will insert any exceptions thrown into a table on "ExceptionLog" on MySql server.

ExceptionLog Table format

idExceptionLog int (AI) User (varchar 45) ErrorMessage (varchart 4000)

The problem is i keep getting the following error. Does anyone know why?

All the classes inside System.Data.SqlClient are used for SQL Server database & not mysql.

In your code, replace SqlCommand with MySqlCommand and SqlConnection with MySqlConnection.

EDIT: See this page for the classes, you could use in this case.
