Property Value

Type Description

A String value which specifies the parameters needed to establish the initial connection.


Use the ConnectionString property to specify a connection string for the default Data Access Layer.

The default sessions and newly created sessions will use the specified connection string when they are connected to a data store, as shown in the following code example.

using DevExpress.Xpo;
using DevExpress.Xpo.DB;

// Retrieve the MS Access database-specific connection string.
XpoDefault.ConnectionString =
    AccessConnectionProvider.GetConnectionString("sample.mdb", "user", "pwd");
// If the default session is connected, disconnect it.
// XpoDefault.Session and Session.DefaultSession can be used interchangeably.
if(XpoDefault.Session.IsConnected) {

// The default data access layer is created and connected to the database
// using the connection string.
