Cannot apply indexing with [] to an expression of type 'System.Data.IDbCommand'

Question

Do you have an idea what might cause the error in the title? It highlights an error in the following part of the code:

        SyncAdapter notesSyncAdapter = notesBuilder.ToSyncAdapter();
        ((SqlParameter)notesSyncAdapter.SelectIncrementalInsertsCommand["@sync_last_received_anchor"]).DbType = System.Data.DbType.Binary;
        ((SqlParameter)notesSyncAdapter.SelectIncrementalInsertsCommand.Parameters["@sync_new_received_anchor"]).DbType = System.Data.DbType.Binary;

Answer 1

You forgot a .Parameters after SelectIncrementalInsertsCommand on the second line.
