The basic problem here is that Json.NET’s DataTableConverter infers each DataColumn.DataType by looking at token values present in the first row only. It works this way because it streams the JSON for the table in rather than loading the entirety into an intermediate JToken hierarchy. While streaming gives better performance with reduced memory use, it … Read more
You have a few alternatives to force your list to be replaced rather than reused: You can add an attribute to the list property indicating that it should be replaced not reused: public class Configuration { [JsonProperty(ObjectCreationHandling = ObjectCreationHandling.Replace)] public List<Tuple<int, int, int>> MyThreeTuple { get; set; } } You can use an array instead … Read more
The reason this is happening is due to the combination of two things: Your class constructors automatically add default items to their respective lists. Json.Net calls those same constructors to create the object instances during deserialization. Json.Net’s default behavior is to reuse (i.e. add to) existing lists during deserialization instead of replacing them. To fix … Read more
@Ilija Dimov is correct–JSON.NET parses JSON floats as doubles by default. If you still want to use JObject instead of creating a full blown POCO for deserialization, you can use a JsonTextReader and set the FloatParseHandling option: var reader = new JsonTextReader(new StringReader(clientString)); reader.FloatParseHandling = FloatParseHandling.Decimal; JObject obj = JObject.Load(reader); Console.WriteLine(obj[“max”].Value<decimal>()); // 1214.704958677686
WCF doesn’t use JavascriptSerializer. It uses DataContractJsonSerializer. And yes, you can replace it with Json.NET by writing a custom message formatter as exemplified in the following blog post.
In the comments it looks like you have decided to resort to using Regex to get rid of the empty objects. One problem with that idea is it probably will not handle the situation where you have what I will call “recursive empty objects”. In other words something like this: { “foo”: { “bar”: {}, … Read more
You could create a root class to deserialize into and use JsonProperty public class Root { // Use the proper type instead of object [JsonProperty(PropertyName = “en.pickthall”)] public IEnumerable<object> EnPickthall { get; set; } public Root() { } } Used as follows Root stuff = JsonConvert.DeserializeObject<Root>(result); foreach(var x in stuff.EnPickthall) { }
You should use JSON.NET or similar library that offers some more advanced options of deserialization. With JSON.NET all you need is adding JsonProperty attribute and specify its custom name that appears in resulting JSON. Here is the example: public class MyClass { [JsonProperty(PropertyName = “24hhigh”)] public string Highest { get; set; } … Now to … Read more
You want JsonSerializer.Populate() or its static wrapper method JsonConvert.PopulateObject(): Populates the JSON values onto the target object. For instance, here it is updating an instance of your Calendar class: public static class TestPopulate { public static void Test() { var calendar = new Calendar { Id = 42, CoffeeProvider = “Espresso2000”, Meetings = new[] { … Read more
The code below should be pretty close to what you are looking for. I made the assumption that there is an outer array, and that arrays can appear anywhere in the hierarchy. (If this is not true, you can simplify the WalkNode method code a bit, but it should work either way.) using System; using … Read more
