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. It provides a consistent model for working with data across various kinds of data sources.
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 query selects all numbers greater than 5 from a collection.
What types of data sources can I use with LINQ?
You can use LINQ with various data sources, including arrays, collections, databases (like SQL Server), XML, and even remote services.
Are there any performance considerations I should be aware of?
Yes, while LINQ is powerful, it can introduce overhead. It's important to consider the size of your data and the complexity of your queries to avoid performance issues.
