JsonSerializerSettings and Asp.Net Core

JsonSerializerSettings and Asp.Net Core

In ASP.NET Core, you can configure the JSON serialization settings for the JsonSerializer used by the framework using the AddJsonOptions method in the Startup class. This method allows you to specify a delegate that takes a JsonSerializerOptions object, which you can use to configure the JSON serialization settings.

Here's an example of how to configure the JSON serialization settings in ASP.NET Core:

public void ConfigureServices(IServiceCollection services) { services.AddControllers().AddJsonOptions(options => { options.JsonSerializerOptions.PropertyNamingPolicy = JsonNamingPolicy.CamelCase; options.JsonSerializerOptions.IgnoreNullValues = true; options.JsonSerializerOptions.Converters.Add(new MyCustomConverter()); }); }

In this example, we're using the AddJsonOptions method to configure the JsonSerializerOptions for the framework's JsonSerializer. We're setting the PropertyNamingPolicy to CamelCase to convert property names to camel case, setting IgnoreNullValues to true to exclude null values from the output, and adding a custom converter using the Converters property.

You can also configure the JSON serialization settings globally by using the Configure<JsonSerializerOptions> method in the ConfigureServices method, like this:

public void ConfigureServices(IServiceCollection services) { services.Configure<JsonSerializerOptions>(options => { options.PropertyNamingPolicy = JsonNamingPolicy.CamelCase; options.IgnoreNullValues = true; options.Converters.Add(new MyCustomConverter()); }); services.AddControllers(); }

In this example, we're using the Configure<JsonSerializerOptions> method to configure the JsonSerializerOptions globally. This method takes a delegate that takes a JsonSerializerOptions object, which you can use to configure the JSON serialization settings. Note that you also need to call the AddControllers method to register the controllers with the framework.
