C# How to know if a given path represents a root drive?
How can I know if 开发者_StackOverflowa given directory is a root drive?
(aside from checking if its path equals to "A:", "B:", "C:", etc.)
Check if DirectoryInfo.Parent is null or not
DirectoryInfo d = new DirectoryInfo("");
if(d.Parent == null) { IsRoot = true; }
you can also get the root by using DirectoryInfo.Root;
Try this:
if (Path.GetPathRoot(location) == location) {...}
It's much more complicated than checking the Parent property.
Determining Whether a Directory Is a Mounted Folder
One approach would be to see if GetVolumeNameForVolumeMountPoint
succeeds.
Of course that won't work for network path, determining if a network drive represents the root directory of a partition may not be possible remotely.
Also Here's another way I found:
public static bool IsLogicalDrive(string path)
{
return (new DirectoryInfo(path).FullName == new DirectoryInfo(path).Root.FullName);
}
if this function returns true, then it means that given path represents a root drive!
Here's another way I found:
public static bool IsLogicalDrive(string path)
{
return Directory.GetLogicalDrives().Contains(path);
}
This one actually checks if the given path represents one of the current system's logical drives.
