How to edit the modified date of a folder/file?

问题

I am creating folders in SP using webdav with HttpWebRequest, MKCOL method.
And I upload files using WebClient.

For both uploaded files and created folders, how can I set their modified date?

I am looking for something similar to Directory.SetLastWriteTime, File.SetLastWriteTime

回答1:

You can use following code for that

//Change the file created time.
File.SetCreationTime(path, dtCreation);
//Change the file modified time.
File.SetLastWriteTime(path, dtModified);

回答2:

 string path = @"c:\DirName";
 Directory.SetLastWriteTime(path, DateTime.Now);
 dt = Directory.GetLastWriteTime(path);
