Efficient use of LINQ to FileInfo objects

Asked by Dabas in Language Integrated Query - LINQ, Microsoft Visual C#.Net, .NET Framework 3.x versions

Tags: C# .NET 3.5

I have a folder with a very large quantity of files in it.
I have written a small console application as per the code snippet using LINQ to Objects

My aim is to count the amount of files in the folder that are between two given dates
Unfortunately, LINQ does not seem to be very efficient, as it still tries to enumerate through all of the files in the folder, even though I am trying to aid its work by sorting the collection and filtering it by creation date.

Is there a way to make this code more efficient?Start Free Trial
