                new IsoDateTimeConverter { DateTimeStyles = DateTimeStyles.AssumeUniversal }
            },
        };
    }
}

It works, but I am unable to deserialize unless I specify the first element explicitly in JsonPropery.

IE: [JsonProperty("f6a1ad82-4b5f-430d-92a0-817927f5beaa")]

In reality, this property is a GUID and subject to change all the time (as well as the possibility of multiple GUID objects in their own array).

I've tried variations of:

public Dictionary<string, NodeId[]> NodeId { get; set; }

but this either results in an exception/failure to deserialize or the object returned is null.

What am I missing?

CodePudding user response：

This was tested using Visual Studio 2019 and serialize libraries. Everything is working properly.

using Newtonsoft.Json

 var deserializedJson= JsonConvert.DeserializeObject<Dictionary<string, List<Message>>>(json);

How to use (examples)

List<Message> result =  deserializedJson.Values.FirstOrDefault();

var startedAt=result[0].StartedAt;
//or
 var startedAt=result.FirstOrDefault().StartedAt;

var  port0=result[0].MessageInput.Attributes.Port;
//or
var  port0=result.Where(r => r.Id== "5a9d3ae5fcf53960035643a7").FirstOrDefault()
.MessageInput.Attributes.Port;

var port1 = result[1].MessageInput.Attributes.Port;
