How do you use LINQ?
We should think of Linq as having a three step process:
- Get the data source, this data source could be anything, a list, an XML file, a table in a Database.
- Create the query, query represents the intent, something that you want to do.
- Execute the query, this is when you actually get the data.
What is the main purpose of LINQ?
The official goal of the LINQ family of technologies is to add “general purpose query facilities to the .NET Framework that apply to all sources of information, not just relational or XML data”. LINQ offers an object-based, language-integrated way to query over data no matter where that data came from.
How is LINQ to SQL used in Visual Studio?

What do you need to know about LINQ queries?

How to write LINQ method that works with two sequences?
Writing a LINQ method that works with two sequences requires that you understand how IEnumerable works. The IEnumerable interface has one method: GetEnumerator. The object returned by GetEnumerator has a method to move to the next element, and a property that retrieves the current element in the sequence.
