When using ASP.NET Core/6 to return an object as JSON we use return Ok(data) which takes the data object and serializes it using camelCase.
But, when I want to serialize an object manually, it does not serialize using camelCase.
Here is how I am attempting to decentralize the object
System.Text.Json.JsonSerializer.Serialize(data)
Is there a service to use in ASP.NET Core that would serialize the object using the default formatter? If not, how can I serialize using camelCase?
You can use the object: JsonSerializerOptions. You have to pass it as a parameter after your object like this:
JsonSerializerOptions options = new JsonSerializerOptions()
{
PropertyNamingPolicy = JsonNamingPolicy.CamelCase
};
System.Text.Json.JsonSerializer.Serialize(data, options);
If you want to ensure that you use the same serializer options as ASP.NET Core, you can inject the options object to your service as follows:
using System.Text.Json;
using Microsoft.AspNetCore.Http.Json;
using Microsoft.Extensions.Options;
class MyService
{
private readonly JsonSerializerOptions _jsonSerializerOptions;
public MyService(IOptions<JsonOptions> jsonOptions)
{
_jsonSerializerOptions = jsonOptions.Value.SerializerOptions;
}
public void MyMethod()
{
var data = new { Foo = "bar" };
var json = JsonSerializer.Serialize(data, _jsonSerializerOptions);
}
}
