Query Expressions Versus Method Calls

LINQ query as method calls

var bigFiles = GetAllFilesInDirectory(@"c:\").
    Where(file => new FileInfo(file).Length > 10000000);
Let’s compare this with the components of the original query:
var bigFiles = from file in GetAllFilesInDirectory(@"c:\")
               where new FileInfo(file).Length > 10000000
               select file;

using where

var bigFiles = from file in GetAllFilesInDirectory(@"c:\")
               where new FileInfo(file).Length > 10000000
               select "File: " + file;

using select

var bigFiles = GetAllFilesInDirectory(@"c:\").
               Where(file => new FileInfo(file).Length > 10000000).
               Select(file => "File: " + file);
