Good day! I have some file called "*.dat" with text into it. So, i try to create attribure "Version" ,but don't know how. Can i do it via c#? Can you write some examples?
Such like this?
File.SetAttributes(path, attributes);
Thank you!

What is your goal? See the version in file properties? Or just save the metadata anywhere? Either way, you should probably consider a simpler alternative like embedding the data inside the file - it will be much more resilient to actions like web download, email attachment and moving between different file systems (many USBs are FAT32, for example)Kobi– Kobi2014-06-02 12:50:14 +00:00Commented Jun 2, 2014 at 12:50

Links to MSDN are very likely one of the most stable out there, so I wouldn't lose my sleep over it.
You're probably struggling because you can't add arbitrary information into a file. There are a known set of attributes you can change using the FileAttribute properties
What you would normally do is provide some information at the start of your file, typically called the file header. This then allows a custom reading implementation to read out the version, without having to read the rest of the file. This is quite standard practise with all the files you're used to, for example a WAV audio file:

The attributes you can change here are the NTFS attributes. Details here: http://msdn.microsoft.com/en-us/library/system.io.fileattributes%28v=vs.110%29.aspx
Version is a resource embedded in an executable file. A similar question was asked here: How do I set the version information for an existing .exe, .dll?

reating "custom" file attributes is not allowed.
You can only set one of the FileAttributes .
Example:
File.SetAttributes(@"C:\myfile.txt", FileAttributes.Hidden);
