Re: MySqlParameter of type Int32 gets "only byte arrays" etc from MySqlBinary

[Greg Adams]

The issue seems to be with the use of a MySqlParameter with a type of MySqlDbType.UInt32. I have traced the serialization logic to a switch statement in MySqlValue GetMySqlValue. Having reached the decision logic, with type=UInt32, unsigned=false, binary=true, the logic drops to the default path, as there is no case for MySqlDbType.UInt32. In the default, because type is binary, it is sent to MySqlBinary which then exceptions out because it is not supposed to receive requests to serialize anything but strings and byte arrays.

I have circumvented the issue, for now, by only using signed integer types.
