Checking when a file was last modified in C# on Windows OS

Question

Hi,

I'm looking to find out a way of seeing when a file was last modified in C#. I have full access to the file.

Thanks in advance

Answer 1

System.IO.File.GetLastWriteTime is what you need.

Answer 2

Just use File.GetLastWriteTime. There's a sample on that page showing how to use it.

Answer 3

You simply want the File.GetLastWriteTime static method.

Example:

DateTime lastModified = System.IO.File.GetLastWriteTime("C:\foo.bar");

Console.WriteLine(lastModified.ToString("dd/MM/yy HH:mm:ss"));
