Remove character from json field name while Deserializing

Question

I have a json that has field names with '_'. However, the class where I need to map these fields doesn't have underscore. As the field names doesn't match I get the values for the mapped class as null. I want to remove the underscore from the json fields before mapping them to the entity class. Can you please suggest which way it can be done - using CustomConverter or using DefaultContractResolver and which one be a better implementation. example json like :

{\"My_UnitOfStudyStatus_Code\":\"1234\"

And corresponding entity class has a field called MyUnitOfStudyStatusCode I need a generic solution that I can use for all my json and for mapping to all corresponding entities.

I was trying to desterilize as below

JsonConvert.DeserializeObject<TEntityType>(jsonString, new IgnoreUnderScoreConverter<TEntityType>()

Where for the converter implementation I was trying and stuck at below :

public override object ReadJson(JsonReader reader, Type objectType, object existingValue, Newtonsoft.Json.JsonSerializer serializer)
        {
            JObject jobject = JObject.Load(reader);
            
            var model = new T();
            //Need to rename fields for jobject 
            serializer.Populate(renamed.CreateReader(), model);

            return model;
        }

But I might be missing here something that I can't rename the fields that I get from jobject before they gets mapped to the entity class. Please suggest.

You can use the JsonPropertyName attribute. eg:

[JsonPropertyName("_name")]
public string Name {get;set;}

this will deserialize correctly even though the property name in json has a underscore in it
