I am passing a JSON payload to an API Controller, and one of the fields is dynamic because the field needs to be passed again as a JSON string to another API. The dotnet core 3.1 middle layer shouldn't be concerned with typing, as the payload will change.
This is the object that is passed into the API Controller:
public class GitHubAction
{
[JsonProperty("Title")]
public string Title { get; set; }
[JsonProperty("Enabled")]
[JsonConverter(typeof(BooleanParseStringConverter))]
public bool Enabled { get; set; }
[JsonProperty("Action")]
[JsonConverter(typeof(ExpandoObjectConverter))]
public dynamic Action { get; set; }
}
Here is a picture of that dynamic
object looks like in VSCode:
When I use JsonConvert.SerializeObject(x.Action);
the string result isn't being properly converted, but instead serializes to ValueKind: "{\"ValueKind\":1}"
.
What I want to get is the action object value as a JSON string, which should look like "{"createRepository":{"onboarding":{"service":{"organization":"foo","repositoryName":"foo-2-service","description":"A test service."}}}}"
Is there a simple solution for serializing a dynamic object?
I had the same problem and I fixed it this way
using System.Text.Json;
string serializedObject = JsonSerializer.Serialize(x.Action); //Instead of use JsonConvert.SerializeObject(x.Action);
Instead of Newtonsoft.Json
you have to use System.Text.Json
.
Use Newtonsoft.Json instead of default System.Text.Json
Add Microsoft.AspNetCore.Mvc.NewtonsoftJson package from nuget and services.AddControllers().AddNewtonsoftJson() in Startup.cs/ConfigureServices()
Try this
var jsonString=s.Action.ToString();
This will give you the json string
If you want to use Newtonsoft.Json then follow this instructions :
in using section use this :
using Newtonsoft.Json;
Then
string serializedObject = JsonConvert.SerializeObject(value);
and for Deserializing use :
var desrializedObject = JsonConvert.DeserializeObject<T>(serializedObject);
You can use Newtonsoft.Json.Converters.ExpandoObjectConverter to help you with this.
dynamic action = new ExpandoObject();
action.YourProperty = new ...;
var converter = new ExpandoObjectConverter();
var jsonString = JsonConvert.SerializeObject(action, converter);
