Can i create 2 SubDirectories at same time C#?

I want to create a simple directory tree like this one, although it doesn't need to have the same name

Directory Tree

Do I need to write it like this:

Directory.CreateDirectory("/home/XXX/Documents/Users/Pepe/datos/");
Directory.CreateDirectory("/home/XXX/Documents/Users/Juan");

Is there any option to create "Pepe" and "Juan" in the same string path?

You can create like.

System.IO.Directory.CreateDirectory("c:/Dir1/Dir2/Dir3");

Think there is no Dir1 at root of c: drive.

It will create folder structure as like Dir1-->Dir2-->Dir3.

If Die1 is there then it will create rest of sub directory.

Same for multiple level.

It sounds like you have a common root directory:

/home/XXX/Documents/Users

and you want to add sub-directories from there. If that is the case and if the goal is to only have to reference the sub-directories, then I would go with @ColinM's approach, but modify it slightly as follows:

private static void CreateDirectories(string directoryRoot, params string[] directories)
{
    foreach (string directory in directories)
    {
        Directory.CreateDirectory(Path.Combine(directoryRoot, directory));
    }
}

Now when you call it, you only need to mention the root once

CreateDirectories("/home/XXX/Documents/Users", "Pepe/datos/", "Juan");

The nice thing about Path.Combine is that you don't have to worry about having a slash / that is either trailing in the directoryRoot or leading in any of the directories--it will make sure it is formatted correctly in the end.

Of course, if you take this approach, you'll need to decide what happens if directories is null--do you create the directoryRoot (assuming it isn't already there), do you throw an error, or do you just return?

To post an answer and offer an alternative, if you only wanted to have one usage of the CreateDirectory method then you could have a method that takes a parameter of params string[] and pass in the directories there when calling the method.

The code would look like so

private static void CreateDirectories(params string[] directories)
{
    foreach (string directory in directories)
    {
        Directory.CreateDirectory(directory);
    }
}

You can call it with

CreateDirectories("/home/XXX/Documents/Users/Pepe/datos/", "/home/XXX/Documents/Users/Juan");

Or you can pass in a string array

CreateDirectories(new [] { "/home/XXX/Documents/Users/Pepe/datos/", "/home/XXX/Documents/Users/Juan"});

I reduce the usage of the System.IO methods doing the above, then I interface the class which allows me to create mocks and then unit test the software I create without performing I/O operation, which brings one scenario where you could use the above except it wouldn't be static.

No there's nothing baked into the BCL to do that; you have to call CreateDirectory for every one.

If you have a collection of directory paths, you can put that inside a loop:

foreach (string dirPath in directoryPaths)
{
    Directory.CreateDirectory(dirPath);
}
