What is LINQ in C# and how can I use it?
LINQ, or Language Integrated Query, is a feature in C# that allows you to query collections in a more readable way.
Can you give me an example of a LINQ query?
Sure! Here's a simple example: var results = from num in numbers where num > 5 select num;
This retrieves numbers greater than 5.
What types of data sources can I use with LINQ?
You can use LINQ with various data sources like arrays, lists, XML, databases, and even remote services.
Are there any performance considerations I should be aware of?
Yes, while LINQ is convenient, it can introduce overhead. It's important to consider the size of your data and the complexity of your queries.
