C# fileinfo class lastwritetime property

Byte[] mtime = new Byte[4];
mtime = Encoding.ASCII.GetBytes(file.LastWriteTime.ToString());
fs.Write(mtime, 0, mtime.Length);

The code is stored as a binary file like "2016-01-15 ?? 5:45:11" <--

I want to know if 'Lastwritetime' have certain properties.

only get date. like "20160115"

Solution

  • If you want only the date part in that format, use:

    file.LastWriteTime.ToString("yyyyMMdd");
