Creation Date and File.Copy Error

Question

I am trying to copy files from one directory to another and test based on the file creation date.

File.Copy(fileName, directory + fileNameOnly, true); 

The problem occurs later in my program when I checked the creation date to make sure it is no more than 5 days old.

 FileInfo file = new FileInfo(fileName); if (file.CreationTime.AddHours(120) < DateTime.Now) {} 

I saw that the creation date when copying back is set to 1980-01-01. This is not useful for my requirements, since I would like to save the creation date from the source file. Is there any other method for comparing dates or is it a copy that loses the value of the creation date.

I think my question is, how can I save the creation date?

Answer 1

Use the File.SetCreationTime method after copying the file.
You can get the time to create the source file using File.GetCreationTime
