Description:
When a connection is successfully opened. Try shutdown the mysql server and cal Ping() method, Ping() will return false as expected but connection state remains Open.

How to repeat:
MySQLConnection m_myConnection = new MySQLConnection();
m_myConnection.ConnectionString = ...
m_myConnection.Open();

// Open succeed... now shutdown the mysql server
// then execute the following code
bool bRes = m_myConnection.Ping(); // bRes is false
System.Data.ConnectionState state = m_myConnection.State; // state is Open !?!

Suggested fix:
Update the connection state when ping fail.
