Working with JSON Data

JSON data can be tricky. The easiest way is to convert it to a dynamic object using AsDynamic(string). Then you can easily use it in your code.

It's important to note that in Typed mode everything is much more strict. 

Since JSON itself is very flexible, you must know what the JSON will contain, to write code which is really type safe. As an alternative you can also always parse it using System.Text.Json.

  • Title: This is a JSON title
  • IsCool: True
  • Sub-item title: sub-item title
  • Is this a list/array? False
  • Are the tags a list? True 
@inherits Custom.Hybrid.RazorTyped
@using System.Collections;

@{
  var someJson = System.IO.File.ReadAllText(App.Folder.PhysicalPath + "/tutorials/json-use/demo.json");
  var thing = Kit.Json.ToTyped(someJson);

<ul>
  <li>Title:
    @thing.String("Title")
  </li>
  <li>IsCool:
    @thing.Bool("IsCool")
  </li>
  <li>Sub-item title:
    @thing.String("SubItem.Title")
  </li>
  <li>Is this a list/array?
    @(thing is IEnumerable)
  </li>
  <li>Are the tags a list?
    @(thing.Get("Tags") is IEnumerable)
