To use the ISO UTC DateTime format as the default JSON output format in an MVC 6 API response, you can configure the JSON serializer settings in your Startup.cs file.
Here's an example of how to do this:
Startup.cs file, add the following code to the ConfigureServices method:services.AddControllers().AddJsonOptions(options => { options.JsonSerializerOptions.Converters.Add(new IsoDateTimeConverter()); }); In this example, we're adding the IsoDateTimeConverter to the JsonSerializerOptions for the JsonOptions of the Controllers.
IsoDateTimeConverter class to your project:public class IsoDateTimeConverter : JsonConverter<DateTime> { public override DateTime Read(ref Utf8JsonReader reader, Type typeToConvert, JsonSerializerOptions options) { return DateTime.Parse(reader.GetString()).ToUniversalTime(); } public override void Write(Utf8JsonWriter writer, DateTime value, JsonSerializerOptions options) { writer.WriteStringValue(value.ToUniversalTime().ToString("o")); } } In this example, we're defining a custom JsonConverter that formats DateTime values as ISO UTC strings using the o format specifier.
[JsonProperty] attribute to any DateTime properties in your model classes that you want to serialize using the ISO UTC format:public class MyModel { public int Id { get; set; } [JsonProperty(PropertyName = "date")] public DateTime Date { get; set; } } In this example, we're using the JsonProperty attribute to specify the property name as date and ensure that it is serialized using the custom IsoDateTimeConverter.
With this configuration, any DateTime values returned by your API will be serialized using the ISO UTC format by default. If you want to use a different format or time zone, you can modify the IsoDateTimeConverter class accordingly.
