You can fill the dictionary using reflection: public Dictionary<String, Object> Dyn2Dict(dynamic dynObj) { var dictionary = new Dictionary<string, object>(); foreach (PropertyDescriptor propertyDescriptor in TypeDescriptor.GetProperties(dynObj)) { object obj = propertyDescriptor.GetValue(dynObj); dictionary.Add(propertyDescriptor.Name, obj); } return dictionary; }
You can use .NET 4’s dynamic type and built-in JavaScriptSerializer to do that. Something like this, maybe: string json = “{\”items\”:[{\”Name\”:\”AAA\”,\”Age\”:\”22\”,\”Job\”:\”PPP\”},{\”Name\”:\”BBB\”,\”Age\”:\”25\”,\”Job\”:\”QQQ\”},{\”Name\”:\”CCC\”,\”Age\”:\”38\”,\”Job\”:\”RRR\”}]}”; var jss = new JavaScriptSerializer(); dynamic data = jss.Deserialize<dynamic>(json); StringBuilder sb = new StringBuilder(); sb.Append(“<table>\n <thead>\n <tr>\n”); // Build the header based on the keys in the // first data item. foreach (string key … Read more
foreach (var data in dynObj.quizlist) { foreach (var data1 in data.QUIZ.QPROP) { Response.Write(“Name” + “:” + data1.name + “<br>”); Response.Write(“Intro” + “:” + data1.intro + “<br>”); Response.Write(“Timeopen” + “:” + data1.timeopen + “<br>”); Response.Write(“Timeclose” + “:” + data1.timeclose + “<br>”); Response.Write(“Timelimit” + “:” + data1.timelimit + “<br>”); Response.Write(“Noofques” + “:” + data1.noofques + “<br>”); foreach … Read more
SelectToken(“data[0].user_id”) doesn’t work because there isn’t an array in your JSON. You should use SelectToken(“data.user_id”) instead. Fiddle: https://dotnetfiddle.net/K0X4ht
As an alternative answer to question 2 (assuming you don’t want to go through the hassle of compiling your own custom version of the Json.NET source) you can create your own custom JsonConverter class to handle decimal, float, and double values. Here’s the version I’m using: class DecimalJsonConverter : JsonConverter { public DecimalJsonConverter() { } … Read more
First off, your models are slightly incorrect. The name properties need to be strings, instead of integers: class Guardian { [JsonProperty(PropertyName = “guardian_id”)] public int ID { get; set; } [JsonProperty(PropertyName = “guardian_name”)] public string Name { get; set; } // <– This } class Patient { [JsonProperty(PropertyName = “patient_id”)] public int ID { get; … Read more
I think this is exactly the kind of comparison you are looking for. It basically says that JSON.Net is better because it among other things… Is faster Has LINQ to JSON support Can convert JSON to and from XML In my opinion the only positive, (and it is a small positive), I can see for … Read more
You are getting this error because you are trying to construct a JObject with a string (which gets converted into a JValue). A JObject cannot directly contain a JValue, nor another JObject, for that matter; it can only contain JProperties (which can, in turn, contain other JObjects, JArrays or JValues). To make it work, change … Read more
Yes, this can be done using a custom ContractResolver. You didn’t show any code, so I’ll just make up an example. Let’s say I have a class Foo as shown below. I want the Id and Name properties in the serialization output, but I’m definitely not interested in the AlternateName and Color. I’ve marked those … Read more
If you need this to only affect a particular field, create a converter type first: public class OnlyDateConverter : IsoDateTimeConverter { public OnlyDateConverter() { DateTimeFormat = “yyyy-MM-dd”; } } and then add this attribute to whatever fields/properties you want this for: [JsonConverter(typeof(OnlyDateConverter))]
