C# DataTable SqlDataReader Example – SqlDataReader Datatable Example C#

"I tried to learn .NET by taking boot camp classes that cost me $6,000. After taking the classes, I discovered tons of free (and very cheap) videos on the internet created by experts in the field. I found the videos to be much better than the classrooms. The videos were presented by Microsoft presenters that knew the material backwards and forwards, and they were much cheaper and better than the classroom teachers. I have spent the last three years organizing and hunting down the videos for my own use and decided that all could benefit by sharing what I found." - Wade Harvey

I AM VERY EXCITED ABOUT THIS AMAZING NEW DISCOVERY
Over 40,000 Top-Notch Video Tutorials (or 3,452 hours) on Lynda.com
I had stumbled across Lynda.com many times before, but never stopped to try it out. I recently took the plunge and started using Lynda.com to help me improve my javascript skills (See Javascript Essential Training 2007 by Dori Smith). It has revolutionized my understanding of the language! I love the fact that the exercise files allow you to follow along in real time with what the instructor is saying. Learning by doing is an extremely powerful technique. I have to give the site an A+ for both quality and content.

I am planning on using Lynda Videos to help me improve in:

1. HTML
2. CSS
3. Classic ASP
4. .NET (included in ASP section)
5. AJAX
6. Silverlight (in Microsoft Section)
7. SharePoint (in Microsoft Section)
8. Web Design
9. Blogging
10. SEO
11. and much more

You can learn more about Lynda.com by watching the 5-minute video at About Lynda.com. If you are only focusing on .NET, you are missing out on the "big picture" and on many of the underlying fundamentals! To be an Ideal Programmer, you need to have the largest knowledge base possible.

Looking for premium .NET Training Videos? The best premium .NET Videos that I have found are at Learn Visual Studio. Those videos are only about 50 cents per hour, as compared to $25 per hour that other sites charge!

LearnVisualStudio is currently having a 25% off sale ($50 savings) and giving away a free membership to TrainingSpot ($60 value) when LVS Lifetime Membership is purchased.
