基于MSDN
的代码段string startFolder = @"c:\Download\";
// Take a snapshot of the file system.
System.IO.DirectoryInfo dir = new System.IO.DirectoryInfo(startFolder);
// This method assumes that the application has discovery permissions
// for all folders under the specified path.
IEnumerable<System.IO.FileInfo> fileList = dir.GetFiles("*.*", System.IO.SearchOption.AllDirectories);
//Create the query
IEnumerable<System.IO.FileInfo> fileQuery =
from file in fileList
where file.Extension == ".txt"
orderby file.Name
select file;
// Create and execute a new query by using the previous
// query as a starting point. fileQuery is not
// executed again until the call to Last()
var newestFile =
(from file in fileList
orderby file.CreationTime
select new { file.FullName, file.CreationTime })
.Last();
Console.WriteLine("\r\nThe newest .txt file is {0}. Creation time: {1}",
newestFile.FullName, newestFile.CreationTime);
// Keep the console window open in debug mode.
Console.WriteLine("Press any key to exit");
Console.ReadKey();
