ServiceStack.Text JsonObject和数组

Question

I have the following code where ServiceStack.Text make the objects which should actually be an array become a string.

var json1 = "{\"x\": [1, 2, 3]}";
var o1 = JsonSerializer.DeserializeFromString<JsonObject>(json1);
var isString1 = o1["x"].GetType() == typeof(string); // Why string and not an array?

var json2 = "{\"x\": [{ \"a\" : true}]}";
var o2 = JsonSerializer.DeserializeFromString<JsonObject>(json2);
var isString2 = o1["x"].GetType() == typeof(string); // Why string and not an array?

What can I do, so that it will be an array? How can I access the array contents?

Answer 1

ServiceStack.Text.JsonObject is a Dictionary<string, string> thus it doesn't act is you expected..

public class JsonObject : Dictionary<string, string>

Deserialization job isn't to guess your target type, it assume you know the structure and by assumption it doing it's magic to make it your intended Type .

You can not make 2 different json structure to deserialize to the same object.

The following will work for the 1st example:

var o1 = JsonSerializer.DeserializeFromString<Dictionary<string, int[]>>

The 2nd example should have a different type, and the following will work, but i would suggest you to write a specific class model for it, the following is very general:

var o2 = JsonSerializer.DeserializeFromString<Dictionary<string, Dictionary<string, bool>[]>>(json2);
