LINQ vs. foreach: Which is better for iterating collections?

What are the main differences between using LINQ and foreach in C#?

LINQ (Language Integrated Query) provides a more concise and readable way to query collections, while foreach is a traditional loop for iterating through items. LINQ can also enable more complex queries with less code.

Are there performance differences between the two?

Yes, LINQ can be less performant for large datasets due to its overhead, but it often results in cleaner code. foreach is generally faster for simple iterations.

When should I prefer LINQ over foreach?

You should prefer LINQ when you need to perform complex queries, transformations, or when you want to write more readable code. Use foreach for simple iterations where performance is critical.

Can you give an example of both in code?

Sure! Here's a LINQ example: var results = myList.Where(x => x > 10); And a foreach example: foreach(var item in myList) { if(item > 10) { // do something } }.
