SqlInfoMessageEventHandler
This delegate defines the method that will handle the
SqlConnection.InfoMessage event. This event fires
whenever a message is received from the data source that has a
severity of 10 or less (and is thus an informational message, not an
error). Messages with higher severities are interpreted as errors and
cause a SqlException to be thrown instead.
public delegate void SqlInfoMessageEventHandler(objectsender, SqlInfoMessageEventArgse);
