Example

The following sample demonstrates how using base classes helps to create data source-independent code.

csharp

public void PrintData(SqlShimConnection myConnection) {
        SqlShimCommand myCommand = (SqlShimCommand)myConnection.CreateCommand();
        myCommand.CommandText = "SELECT AccountID, \"Account Name\", Phone FROM Accounts";
        myConnection.Open();
        SqlShimDataReader myReader = myCommand.ExecuteReader();
        try {
                while (myReader.Read()) {
                        Console.WriteLine(myReader.GetString(0) + " " + 
                                myReader.GetString(1) + " " + myReader.GetString(2));
                }
        }
        finally {
                myReader.Close();
                myConnection.Close();
        }
}

Visual Basic

Public Sub PrintData(ByVal myConnection As SqlShimConnection)
        Dim myCommand As SqlShimCommand = myConnection.CreateCommand()
        myCommand.CommandText = "SELECT AccountID, \"Account Name\", Phone FROM Accounts"
        myConnection.Open()
        Dim myReader As SqlShimDataReader = myCommand.ExecuteReader()
        Try
                While myReader.Read()
                        Console.WriteLine(String.Concat(myReader.GetString(0), " ", _
                                myReader.GetString(1), " ", myReader.GetString(2)))
                End While
        Finally
                myReader.Close()
                myConnection.Close()
        End Try
End Sub
