There is no language-specific way to do this, however the OS provides the required functionality. In a unix system, the stat function is what you need. There is an equivalent _stat function provided for windows under Visual Studio. So here is code that would work for both: #include <sys/types.h> #include <sys/stat.h> #ifndef WIN32 #include <unistd.h> … Read more
Expires and Cache-Control are “strong caching headers” Last-Modified and ETag are “weak caching headers” First the browser checks Expires/Cache-Control to determine whether or not to make a request to the servers. If it has to make a request, it will send Last-Modified/ETag in the HTTP request. If the Etag value of the document matches that, … Read more
According to RFC 2616 – section 13.3.4, an HTTP 1.1 Client MUST use the ETag in any cache-conditional requests, and if both an ETag and Last Modified are present, it SHOULD use both. The ETag header is considered a strong validator (see section 13.3.3), unless explicitly declared weak by the server, whereas the Last Modified … Read more
System.IO.File.GetLastWriteTime is what you need.
You could use below code: DateTime creation = File.GetCreationTime(@”C:\test.txt”); DateTime modification = File.GetLastWriteTime(@”C:\test.txt”);
Use os.utime: import os os.utime(path_to_file, (access_time, modification_time)) More elaborate example: https://www.tutorialspoint.com/python/os_utime.htm
how about something like this… var directory = new DirectoryInfo(“C:\\MyDirectory”); var myFile = (from f in directory.GetFiles() orderby f.LastWriteTime descending select f).First(); // or… var myFile = directory.GetFiles() .OrderByDescending(f => f.LastWriteTime) .First();
