Limit Number of Results being returned in a List from Linq

I'm using Linq/EF4.1 to pull some results from a database and would like to limit the results to the (X) most recent results. Where X is a number set by the user.

Is there a way to do this?

I'm currently passing them back as a List if this will help with limiting the result set. While I can limit this by looping until I hit X I'd just assume not pass the extra data around.

Just in case it is relevant... C# MVC3 project running from a SQL Server database.

Is LINQ inefficient?

Conclusion. It would seem the performance of LINQ is similar to more basic constructs in C#, except for that notable case where Count was significantly slower. If performance is important it's crucial to do benchmarks on your application rather than relying on anecdotes (including this one).

Is LINQ good for performance?

LINQ syntax is typically less efficient than a foreach loop. It's good to be aware of any performance tradeoff that might occur when you use LINQ to improve the readability of your code. And if you'd like to measure the performance difference, you can use a tool like BenchmarkDotNet to do so.

Is LINQ to SQL deprecated?

No it is not.

Use the Take function

int numberOfrecords=10; // read from user listOfItems.OrderByDescending(x => x.CreatedDate).Take(numberOfrecords) 

Assuming listOfItems is List of your entity objects and CreatedDate is a field which has the date created value (used here to do the Order by descending to get recent items).

Take() Function returns a specified number of contiguous elements from the start of a sequence.
