Toolbelt.Text.Json.Serialization.DictionaryStringObjectJsonConverter 1.0.0

DictionaryStringObjectJsonConverter

Summary

This is an attribute and a converter on the System.Text.Json infrastructure to deserialize a JSON string to a Dictionary<string, object> object with each value of appropriate basic type, not System.Text.JsonElement.

Usage

1. Add the Toolbelt.Text.Json.Serialization.DictionaryStringObjectJsonConverter NuGet package to your .NET project.

dotnet add package Toolbelt.Text.Json.Serialization.DictionaryStringObjectJsonConverter

2. Add the [DictionaryStringObjectJsonConverter] attribute to a property of the Dictionary<string, object> type.

using Toolbelt.Text.Json.Serialization;

public class MyType
{
    [DictionaryStringObjectJsonConverter]
    public Dictionary<string, object?> Items { get; set; } = new();
}

3. You can deserialize a JSON string to an object of the Dictionary<string, object> type.

using System.Text.Json;

var json = @"{\"items\": {
    \"Lorem\": 1,
    \"ipsum\": \"Two\", 
    \"amets\": [3.4, 5.6],
    \"dolor\": true
  }
}";

var obj = JsonSerializer.Deserialize<MyType>(json);
obj.Items["Lorem"]; // -> 1, typeof(int)
obj.Items["ipsum"]; // -> "Two", typeof(string)
obj.Items["amets"]; // -> new[]{ 3.4, 5.6 }, typeof(double[])
obj.Items["dolor"]; // -> true, typeof(bool)

If you didn't add the [DictionaryStringObjectJsonConverter] attribute to a property of the Dictionary<string, object> type, you would get all of the values in that dictionary object as the System.Text.JsonElement struct value instead of an appropriate basic type value of the .NET.
