fomat Json objects

in c# need to create this structure. Adding the children object I seem to be having trouble with children property to render below.
Current code renders like

 [
        {
            id: 1,
            name: 'root1',
            children: [
               "id:" 2, name: 'child1' ,
               "id:" 3, name: 'child2' 
            ]
        }
    ];

Open in new window

The way it should render is like this below.

 [
        {
            id: 1,
            name: 'root1',
            children: [
                { id: 2, name: 'child1' },
                { id: 3, name: 'child2' }
            ]
        }
    ];

properties.

        public int id { get; set; }
        public string name { get; set; }
        public IList<string> children { get; set; }

class

 var attachmentsList = new List<ModelDto>();
 FileInfo[] files = dinfo.GetFiles();
                
                foreach (FileInfo file in files)
                {
                    attachmentsList.Add(new ModelDto
                    {
                      
                        id = i + 1,
                        name = "Folder " + i + 1,
                        children = new List<string>
                         {
                            id = i + 1,
                            name = file.name,
                   
                        }
                    });
     
                    i++;

                }

 var attachmentsList = new List<RootObject>();
 attachmentsList.Add(new RootObject
                    {
                        id = i + 1,
                        name = "Folder" + i + 1,
                        children = new List<Child>()

Open in new window

Ok this is where I get stuck at. Cannot add the name and the id inside the children also.

This?

            var attachmentList = new List<RootObject>();
            attachmentList.Add(
                new RootObject()
                {
                    id = i + 1,
                    name = "Folder" + (i + 1).ToString(),
                    children = new List<Child>()
                });

yes but children = new List<Child>() cannot add the other properties. tryied the other ways in json.net but since I have to return a list the other ways will not let me.
