Apparently the MySqlCommand that you create there is a custom type in your solution and not the "real" MySqlCommand, which is why you can't assign it to the .SelectCommand-property of the DataAdapter.

The first question I would try to solve is why there is a custom class MySqlCommand (under the namespace "lgugabaldon") in your solution. What is its purpose and should it actually be used somehow for this task? (It's very uncommon to have a class with such a name in a custom namespace!)

Maybe you can ignore it and just use the real MySqlCommand by either removing the using-directive for the lgugabaldon-namespace or by prefixing MySqlCommand with the namespace (MySql.Data.MySqlClient.MySqlCommand), which you would have to do for the declaration of COMMAND and for the new-expression.

Maybe you should even remove the MySqlCommand class in the lgugabaldon-namespace but I can't say for sure because I don't know why it's there in the first place.
