C# 2010 Check If Hidden File Exists

Question

Just that.  I'm trying to make a backup on some databases, automatically set to hidden and squirreled away in a seldom-clicked folder.

Catch is, when they're set to hidden, System.IO.File.Exists doesn't notice it, and I haven't figured out how to merge

if ((at2 & FileAttributes.Hidden) == FileAttributes.Hidden) with Exists.

I just want it to come out like

if(hidden file exists) {overwrite}

else(if it doesn't) {//set error handling}

Answer 1

Try this:

try
{
         if( ( new FileInfo( path ).Attributes & FileAttributes.Hidden ) == FileAttributes.Hidden )
         {
                 // file is hidden
         }
         else
         {
                 // file is not hidden
         }
}
catch( FileNotFoundException )
{
         // file does not exist
}

File.Exists should return true for an hidden file. However, it will return false if you're checking the existence of a folder. Use Directory.Exists to check a folder.
