如何使用Newtonsoft.JSON和C＃遍历嵌套的JSON字段（并且不使用dynamic关键字）

Question

The below JSON file contains the field ' tileproperties '. Within tileproperties there are numbers from 0 to 19.

In this particular case, the amount of numbers are not fixed and the JSON file could contain many more.

Underneath everyone of these numbers there is the field name TileType , with a string value (for example "river01", "river02" etc).

I would like to read this JSON file and create a dictionary. The key would be the number and the value would be the TileType . In particular I would like to use Newtonsoft.JSON, C# and I am unable to use the dynamic keyword ( as suggested in a similar question on stack overflow )

I am unsure how to iterate through the tileproperties field as it does not appear to be formatted as an array (like the data field).

If you just need the tileproperties and not the rest, you can use this:

var tileTypes = JObject.Parse(json)
    ["tilesets"][0]["tileproperties"].Children<JProperty>()
    .ToDictionary(x => x.Name, x => x.Value["TileType"].Value<string>());
