Read Directories from a Mapped Network Drive

Question

I'm trying to get all the sub-directories of a Directory.

This is the line of code that throws an exception

var projectNames = Directory.GetDirectories("Z:").ToList();

The Exception is DirectoryNotFoundException I searched in Microsoft's Documentation and found that this Exception should only be thrown if the Directory is unmapped or does not exist, but here in this case the path exists.

I also tried to search for other reasons that can throw this exception and I found nothing.

Z: is not a directory. It is drive. do you mean you want to list all directories from a drive ? — Amit Verma, Jul 04 '21 at 11:04
@AmitVerma Yes, Exactly. Is it not considered as a `Directory`? — Mostafa Tarek Yassien, Jul 04 '21 at 11:06
z:\ is a directory, z: is not. I've crashed into that myself. — Clay, Jul 04 '21 at 12:31

Try this, to get list of directories from drive

System.IO.DriveInfo di = new System.IO.DriveInfo(@"Z:\");
System.IO.DirectoryInfo dirInfo = di.RootDirectory;

var dir = dirInfo.GetDirectories();

if this has solved problem then accept it so that this can help others. – Amit Verma Jul 04 '21 at 11:12
I'm implementing this method right now, but it returns the Data as `DirectoryInfo` DataType, even when I convert it `ToString()`, it converts to `char`. I'm testing it now to see what is the output from it. – Mostafa Tarek Yassien Jul 04 '21 at 11:16
ok. Let me know in case you face any issue. – Amit Verma Jul 04 '21 at 11:17
Tried it, Same Exception – Mostafa Tarek Yassien Jul 04 '21 at 11:34
what is your exact requirement ? Do you need only directory name in the drive or you also need sub directories in directory. Do you need name with complete path ? – Amit Verma Jul 04 '21 at 11:35
The Main Requirement is to get all the sub-Directories from this Path as a List – Mostafa Tarek Yassien Jul 04 '21 at 11:39

Try this for your new rquirement

System.IO.DriveInfo di = new System.IO.DriveInfo(@"Z:\");
System.IO.DirectoryInfo dirInfo = di.RootDirectory;

//Excluding Hidden and System Directories

List<string> dir = dirInfo.GetDirectories().Where(x=>x.Attributes== FileAttributes.Directory && x.Attributes!=FileAttributes.Hidden && x.Attributes!= FileAttributes.System).Select(x=>x.Name).ToList();

Same Error >> System.IO.DirectoryNotFoundException: 'Could not find a part of the path 'Z:\'.' – Mostafa Tarek Yassien Jul 04 '21 at 11:52
it's working on different machines. DO you have z Drive on your machine ? Can you explore more about your z drive. – Amit Verma Jul 04 '21 at 11:53
Yes, i do have the "Z" Drive on the Machine , it is a Mapped network Drive – Mostafa Tarek Yassien Jul 04 '21 at 11:57
This thing should be mentioned in question. – Amit Verma Jul 04 '21 at 12:00
I didn't think it would make a difference – Mostafa Tarek Yassien Jul 04 '21 at 12:14
are you able to read from your original drives ? – Amit Verma Jul 04 '21 at 12:24
Yes, I can. Also, I reached a solution for this problem, I should use the full path to the Directory including `server name`. – Mostafa Tarek Yassien Jul 04 '21 at 12:27
great. it means my solution is correct for the original drives as it was in question. – Amit Verma Jul 04 '21 at 12:32
The Line of Code in the Question works by itself, the issue was the network Drive itself. – Mostafa Tarek Yassien Jul 04 '21 at 17:03

I Found the Solution, by referring to this answer

I should Write the Full Path for the mapped drive such as this

var projectNames = Directory.GetDirectories(@"\\10.1.7.5\Projects").ToList();
