private static void ChangeSqlDatabase(string connectionString)
{
    // Assumes connectionString represents a valid connection string
    // to the AdventureWorks sample database.
    using (SqlConnection connection = new SqlConnection(connectionString))
    {
        connection.Open();
        Console.WriteLine("ServerVersion: {0}", connection.ServerVersion);
        Console.WriteLine("Database: {0}", connection.Database);

        connection.ChangeDatabase("Northwind");
        Console.WriteLine("Database: {0}", connection.Database);
    }
}
Private Sub ChangeSqlDatabase(ByVal connectionString As String)
    ' Assumes connectionString represents a valid connection string
    ' to the AdventureWorks sample database.
    Using connection As New SqlConnection(connectionString)

        connection.Open()
        Console.WriteLine("ServerVersion: {0}", connection.ServerVersion)
        Console.WriteLine("Database: {0}", connection.Database)

        connection.ChangeDatabase("Northwind")
        Console.WriteLine("Database: {0}", connection.Database)
    End Using
