Retrieving directory and file structure using JSON.Net ( but without "directory", "file" keywords)

I used JSON.Net to retrieve directory and file structure recursively. Referred this link( Is there a way to directly get a directory structure and parse it to Json in C#?). The result retreived as shown

RootDir
{
"directory":
{
    "dirA": {
        "file" : [ "file0.txt", "file1.jpg" ]
    },
    "emptyDir": {
    }
},
"file": [ "file2.png" ]
}

But I would like to exclude the "directory" and "file" keywords from the structure. My structure should look like this

RootDir
{
    "dirA": {
        " "file0.txt", "file1.jpg" 
    },
    "dirB": {
    }
},
 "file2.png"

I wanted only the directory names and file names rather than getting the directory names under a keyword and filenames under another keyword. Please help.

Thanks

You can't get exactly the result you showed, because it would be invalid JSON. However, you can come pretty close. Try something like this:

public static string GetDirectoryAsJson(string path)
{
    return GetDirectoryAsJObject(new DirectoryInfo(path)).ToString();
}

public static JObject GetDirectoryAsJObject(DirectoryInfo directory)
{
    JObject obj = new JObject();
    foreach (DirectoryInfo d in directory.EnumerateDirectories())
    {
        obj.Add(d.Name, GetDirectoryAsJObject(d));
    }
    foreach (FileInfo f in directory.GetFiles())
    {
        obj.Add(f.Name, JValue.CreateNull());
    }
    return obj;
}

Then use it like this (for example):

string json = GetDirectoryAsJson(@"C:\Users\JohnDoe\Documents");

If the folder structure inside C:\Users\JohnDoe\Documents looked like this:

dirA
    dirA1
        foo.txt
    file0.txt
    file1.jpg
dirB
file2.png

Then the resulting JSON would look like this:

{
  "dirA": {
    "dirA1": {
      "foo.txt": null
    },
    "file0.txt": null,
    "file1.jpg": null
  },
  "dirB": {},
  "file2.png": null
}
