We can use the following code snippet to connect to multiple databases.

DLLs to Add as Reference

1. Microsoft.Practices.EnterpriseLibrary.Common.dll
2. Microsoft.Practices.EnterpriseLibrary.Data.dll
3. Microsoft.Practices.ServiceLocation.dll

The snippet:

var builder = new ConfigurationSourceBuilder();

        builder.ConfigureData()
               .ForDatabaseNamed("LocalSqlServer1")
                 .ThatIs.ASqlDatabase()
                 .WithConnectionString(@"Data Source=PCNAME\SQLEXPRESS;Initial Catalog=ContactDB;Integrated Security=True")
               .ForDatabaseNamed("LocalSqlServer2")
                 .ThatIs.ASqlDatabase()
                 .WithConnectionString(@"Data Source=PCNAME\SQLEXPRESS;Initial Catalog=MyDB;Integrated Security=True");

        var configSource = new DictionaryConfigurationSource();
        builder.UpdateConfigurationWithReplace(configSource);

Microsoft.Practices.EnterpriseLibrary.Common.Configuration.EnterpriseLibraryContainer.Current = EnterpriseLibraryContainer.CreateDefaultContainer(configSource);      

Database destinationDatabase = DatabaseFactory.CreateDatabase("LocalSqlServer2");
