How to globally set default options for System.Text.Json.JsonSerializer?

by

You can create an extension method. Here’s an example

I use separate methods vs having to build special settings, so that all the settings will be in a single spot and easily reusable.

public static class DeserializeExtensions
{
    private static JsonSerializerOptions defaultSerializerSettings = new JsonSerializerOptions();

    // set this up how you need to!
    private static JsonSerializerOptions featureXSerializerSettings = new JsonSerializerOptions();


    public static T Deserialize<T>(this string json)
    {       
        return JsonSerializer.Deserialize<T>(json, defaultSerializerSettings);
    }

    public static T DeserializeCustom<T>(this string json, JsonSerializerOptions settings)
    {
        return JsonSerializer.Deserialize<T>(json, settings);
    }

    public static T DeserializeFeatureX<T>(this string json)
    {
        return JsonSerializer.Deserialize<T>(json, featureXSerializerSettings);
    }
}

Then you call it as a method on a string, whether literal or a variable.

    Car result = @"{""Wheels"": 4, ""Doors"": 2}".DeserializeFeatureX<Car>();
