If you just read my question carefully, you'll know my problem is I already built my application and I cannot go through all DAL code again specially I used .net tiers technology to build that DAL

you don't need to do this, there is a better library I found.
here the link:

you just need to download the files in the bottom of the page then add the DLL to your solution and see the example in the other file to know how to use, believe me it's the easiest library I found
good luck

i modified it thank you
