Using API outside kentico

varinder-kudosweb
Hi

Im trying to build a .net mvc web api (which will work similar to kentico REST)
Followed docs (http://devnet.kentico.com/docs/devguide/index.html?using_api_and_cms_controls_outside_cms_project.htm) everything connects fine.

Id like to generate xml/json data containing all the documents (for the requested documenttype) with custom fields only.

For example,
- created a custom documenttype and called it "cms.foo"
- added two fields to cms.foo "name" and "description"
- created 10 cms.foo in the site tree.

Now-
- requesting "http://localhost/api/documenttype/cms.foo"

- In code - this is where im stuck -

 TreeProvider tp = new TreeProvider();
DataSet ds = tp.SelectNodes("CorporateSite", "/%", "en-us", true, "cms.foo", "", "", -1, true);

Im struggling how to filter that dataset down to its bare bones and generate a json out of it that looks something like this:

[
  {
      "cmsFooId": 1,
      "name": "test",
      "description": "test description"
  },
  {
      "cmsFooId": 2,
      "name": "test 2",
      "description": "test description 2"
  }
...
]
