c# DeSerialize NaN values into JSON in using System.Text.Json.Serialization

Question

I Need to convert NaN in Json(as it is not JSON) to Double using using System.Text.Json.Serialization

For example, I am having following JSON:

{ "Amount": NaN }

@pianoboy11 , you could use JsonSerializerSettings to give the default value.

Like the following code:

  static void Main(string[] args)  
        {  
            var options = new JsonSerializerOptions  
            {  
                NumberHandling = JsonNumberHandling.AllowReadingFromString | JsonNumberHandling.AllowNamedFloatingPointLiterals  
            };  
            Test test = new Test();  
            test.Name = "test1";  
            test.Amount = double.NaN;  
            Console.WriteLine(JsonSerializer.Serialize(test,options));  
        }  
      
     public class Test  
        {  
            public string Name { get; set; }  
      
            public double Amount { get; set; }     
      
        }

The solution provided it's for JSON.net, not for System.Text.Json.Serialization which uses "JsonSerializerOptions"
