For now 开发者_JS百科I know SQL and want to write a database program in C#. I tried to read MSDN but it is too difficult for me. I need a book which can explain how ADO.NET works and give some useful examples. I'm not pro in C# also.

P.S. It would be great if the version of ADO.NET explained in this book is 3.5.

Professional ADO.net 2 by Wrox is a good book. You can download it for free from here
