JsonConvert.SerializeObject（）在使用DateTime字段序列化类时失败

Question

I'm having a class with only private fields and their public getter-setters. I need to convert class object into JSON String hence I'm using JSON.Net.

Following is a simple snippet to convert class object into a JSON string.

MyClass obj = new MyClass();
string json = JsonConvert.SerializeObject(obj);
Console.WriteLine(json);

But the method SerializeObject throws StackOverflowException at field in MyClass of type DateTime . What's happening here?

Update

Following is how MyClass looks like (as it is, I don't mind sharing the actual class)

    class MyClass
    {
        private int _Model;
        public int Model
        {
            get
            {
                return _Model;
            }
            set
            {

                _FullLoad = value;
            }
        }
    }

Also, I'll have another class which will have MyClass type field (along with its own similar set of fields), which is going to be converted into JSON string too, and that shouldn't be a problem since JSON.Net is said to support that situation too.

Note: I'm new to C# but I've previously worked with JSON in Java, where I get to play with JSONObject and JSONArray , and they were pretty straight forward.

Answer 1

It looks like your TestEndTime property's getter references itself. Therefore when Json.NET tries to serialize it, it recursively accesses itself and causes the StackOverflowException.

Hope that helps!
