In fact, there is an easy way to convert a C# object to JSON using Json.NET.

You simply create a List<> that contains the data you want and then call 

var wrapper = new { TreeData= list };
string json = JsonConvert.SerializeObject(wrapper);

Using JSON.NET:

JToken GetDirectory(DirectoryInfo directory)
{
    return JToken.FromObject(new
    {
        directory = directory.EnumerateDirectories()
            .ToDictionary(x => x.Name, x => GetDirectory(x)),
        file = directory.EnumerateFiles().Select(x => x.Name).ToList()
    });
}

Example usage:

var json = GetDirectory(new DirectoryInfo("...some path...")).ToString();

This will give you JSON that looks something like this:

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

You can create custom classes like:

abstract class DirectoryChildItem
{
    public string Name { get; set; }
}

class Directory : DirectoryChildItem
{
    public List<DirectoryChildItem> Childs { get; set; }
}

class File : DirectoryChildItem
{
}

Then you should traverse your file system using static class System.IO.Directory and create items using classes above. After traversing file system use "return Json(obj)" method in your ASP.NET MVC action
