How to tell Json.Net globally to apply the StringEnumConverter to all enums

How to tell Json.Net globally to apply the StringEnumConverter to all enums

To globally apply the StringEnumConverter to all enums when using JSON.NET (Newtonsoft.Json), you can set the JsonSerializerSettings.Converters property to include the StringEnumConverter. This setting will be applied to all enums during serialization and deserialization throughout your application.

Here's how you can do it:

using Newtonsoft.Json; using Newtonsoft.Json.Converters; class Program { static void Main() { // Create an instance of JsonSerializerSettings JsonSerializerSettings settings = new JsonSerializerSettings(); // Add the StringEnumConverter to the Converters list settings.Converters.Add(new StringEnumConverter()); // Use the JsonSerializerSettings with your JSON operations string jsonString = JsonConvert.SerializeObject(yourObject, settings); YourObject deserializedObject = JsonConvert.DeserializeObject<YourObject>(jsonString, settings); } }

In the example above, we create an instance of JsonSerializerSettings and add the StringEnumConverter to its Converters list. This will ensure that all enums will be serialized and deserialized as strings, using their ToString() method during serialization and Enum.Parse() method during deserialization.

Now, whenever you use JsonConvert.SerializeObject() or JsonConvert.DeserializeObject(), the StringEnumConverter will be automatically applied to all enums. This eliminates the need to specify the converter for each enum individually and provides a global solution for your application.

Keep in mind that setting StringEnumConverter globally might impact other parts of your application if you have custom handling for specific enums. In such cases, you can use separate JsonSerializerSettings instances with specific converters for different serialization scenarios.
