I'm confused about the differences between these two special folders.
Here's a code snippet that writes the output of each, but they output the same thing.
string path = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string pathTwo = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
Console.WriteLine(path);
Console.WriteLine(pathTwo);
Console.ReadKey();
According to the MSDN documentation (for .NET 1.1):
Desktop
The logical Desktop rather than the physical file system location.
DesktopDirectory
The directory used to physically store file objects on the desktop. Do not confuse this directory with the desktop folder itself, which is a virtual folder.
What does it mean when it says the logical Desktop rather than the physical file system location? Also, what is a virtual folder in simple terms?
In the newer .NET 4 version of the documentation, I noticed that they removed the Desktop entirely and only left DesktopDirectory.
Why is this?
回答1:
A directory is a location in the file system. A folder is a location in the shell namespace. A directory is a kind of folder. A virtual folder is not necessarily backed by a directory. For example consider libraries or search folders.
The user's desktop directory is a location in the file system. The desktop folder merges that with virtual items like all users items, recycle bin, shortcut to documents folder etc.

The true answer is that those can be different especially width profiles on servers. The user might be running a desktop as from a fileshare, or have it on a local system... If redirected the OS normally doesnt inform other software that it has done that. But if you realy want to get there...
