Example

The following example shows how you should use the OleDb storage in your applications.
C#Copy Code
// ... Other code 
 
// Creates a new ObjectContext that uses an OleDb database as storage. 
// You should only pass an instance of the storage to your ObjectContext. 
// That's it! Nothing more. The methods of the storage are accessed 
// by the context internally. 
ObjectContext context = new ObjectContext( 
    new OleDbStorage("... some ConnectionString ...")); 
 
// ... Other code

Remarks

This class encapsulates a physical OleDb database. It is used to access to an Oracle database that is installed somewhere on your or on a remote machine. The storage implements the basic interfaces, such as IStorage for the basic storage IO functinality and ITransactionStorage for the transaction management.

Attention: You should not access the methods of the storage directly but instead register the storage with your instances of the ObjectContext. The ObjectContext accesses the methods internally to get the objects from the storage.
