This isn't mono specific, but there're a lot of smart people in this list so here I go :)
Something simular is probably in the Mono sources but I don't really get it
I'm trying to load DataProviders at runtime (defined by XML files which are in the ..\plugin directory of the application)
First I would like to know what the difference is between
Assembly.CreateInstance() and Activator.CreateInstanceFrom()
As far as I can see they both to the same even though one is in the reflection namespace and the other in the remoting namespace.
Second this code I can't get to work:
Assembly DataProvider;
DataProvider = Assembly.LoadFrom(@"bytefx\ByteFX.Data.dll");
object dbConnection = DataProvider.CreateInstance("ByteFX.Data.MySqlClient.MySqlConnection",false);
MessageBox.Show(dbConnection.ToString()); // Outputs: "ByteFX.Data.MySqlClient.MySqlConnection"
IDbConnection dbConn = (IDbConnection)dbConnection; // This throws an exception --> Invalid cast
But MySqlConnection implements IDbConnection, it really does :)
I also tried this instead:
object conn = Activator.CreateInstanceFrom( @"ByteFX.Data.dll","ByteFX.Data.MySqlClient.MySqlConnection").Unwrap();
MessageBox.Show(conn.ToString());
IDbConnection dbConnection = (IDbConnection)conn;
This has exactly the same result, the message box shows the right name, but I get an invalid cast in the next line.
How can I solve this ?
Thnx.
Timothy.
