问题
I am interested how can I find the connection string in order to be able to connect to MySQL Server 5.1.50 using OleDbConnection(C#).
I used this auto generated string (after adding new data source in Visual Studio):
server=localhost;User Id=MyID;password=MyPassword;database=MyDatabase
but I always get the same error message:
An OLE DB Provider was not specified in the ConnectionString. An example would be, 'Provider=SQLOLEDB;'.
I have tried different providers but neither of them seems to work.
回答1:
Is there a reason you aren't using the MySQL .NET connector? Anyways, I think you need to add
Provider=MySQL Provider; to your connection string.
try this as your connection string:
Provider=MySQL Provider;server=localhost;User Id=MyID;password=MyPassword;database=MyDatabase;
The MySQL.NET connector fully implements the ADO.NET interface. Every command is identical to using the System.Data.SqlClient namespace.
