Question

How to determine if a remote path was a file or directory using C # .Net?

Answer 1

Assuming the file / directory really exists, you can use two static methods:

• System.IO.File.Exists ()
• System.IO.Directory.Exists ()

Both take one string argument and return a boolean if the file / directory exists.

- , / - , - " /" /, , () . ", " ", " . :

• A: ( )
• B:

:

• c:\windows\ -
• c:\windows - B
• c:\windows\notepad.exe -
• c:\windows\system32\drivers\etc\hosts - A
