问题 I am getting error while deserializing jsonString. Error is Type 'oodleListingsUser' is not supported for deserialization of an array. My code of deserialization is string jsonString = new WebClient().DownloadString("http://api.oodle.com/api/v2/listings?key=TEST&region=region_value&category=category_value&format=json"); JavaScriptSerializer ser = new JavaScriptSerializer(); jsonOodleApi p = ser.Deserialize<jsonOodleApi>(jsonString); My class defination of jsonOodleApi is public class

问题 MandrillApp API supposedly sends a JSON-encoded array of the messages with the mime type application/x-www-form-urlencoded . The problem I have encountered is that the data received looks like: mandrill_events=%5B%7B%22event%22%3A%22send%22 %2C%22msg%22%3A%7B%22ts%22%3A136510999...etc Url decoded it is: mandrill_events=[{"event":"send","msg":{ "ts":1365109999,"subject"...etc I try to deserialize this string into a class that represents the JSON data but the JSON.NET deserializer spits out an

问题 I suppose this is another entry in my series of questions, but I'm stuck again. This time, I'm having trouble working with a JArray of JObjects and determining the Property.Value type for each element in the JArray... My code is here: https://dotnetfiddle.net/bRcSAQ The difference between my previous questions and this question is that my outer Linq query gets both JObject and JArray tokens, so that's why I have an if (jo is JObject) at Line 40 and a if (jo is JArray) at Line 48. Once I know

问题 Something I have just picked up in my winforms app My app does an http call to a web Api service as follows HttpClient _client = new HttpClient(); _client.Timeout = new TimeSpan(0, 3, 0); _client.BaseAddress = new Uri("http://Myserver/MyApp"); _client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); HttpResponseMessage response = _client.PostAsJsonAsync("api/Addin", newObject).Result; Nothing fancy, but as soon as you install Newtonsoft.Json (V6.0.3)

问题 Is there a way to set an attribute by the path, using Json.NET? JObject o = JObject.Parse(@"{ 'CPU': 'Intel', 'Drivers': { 'Mouse': 'HPQ', 'VideoCard' : 'NVidia' } }"); //something like that o.SetByPath("Drivers.VideoCard") = "Intel"; Is it possible? By the way, I know that I can do this: o["Drivers"]["VideoCard"] = "Intel"; but that's not what I'm looking for. 回答1: The JObject.SelectToken and JToken.Replace methods can be used here to achieve essentially the same effect. static void Main

问题 This is the code: public class ParameterDictionary : Dictionary<HydroObjectIdentifier, string> { public void WriteToJson(string jsonFilePath) { string json = Newtonsoft.Json.JsonConvert.SerializeObject(this, formatting: Newtonsoft.Json.Formatting.Indented); System.IO.File.WriteAllText(jsonFilePath, json); } } public struct HydroObjectIdentifier { public string Name { get; set; } public string TypeName { get; set; } public HydroObjectIdentifier(string name, string typeName) { this.Name = name;

问题 This question already has answers here : JsonConvert.SerializeObject always return {} in XamarinForms (2 answers) Closed last year . Everyone got this question a lot, and I tried almost everything but none of it works for me. So I am developing in Xamarin.Forms and is about to send my data to the server. I have this class: public class Customer { public string FirstName { get; set; } public string LastName { get; set; } public string BirthDate { get; set; } public string Password { get; set;

问题 I've got this code to try to open a .json file and read it: [Route("{unit}/{begindate}")] public string Get(string unit, string begindate) { string _unit = unit; string _begindate = String.Format("{0}01", PlatypusWebReportsConstsAndUtils.HyphenizeYYYYMM(begindate)); string appDataFolder = HttpContext.Current.Server.MapPath("~/App_Data/"); // semi-hardcoded file name for now string jsonFilename = string.Format("PoisonToe_{0}_{1}.json", _unit, _begindate); string fullPath = Path.Combine

问题 When I set Json.NET to serialize with TypeNameHandling set to TypeNameHandling.Auto, it correctly sets $type for child properties of an object but does not do so for the root object being serialized. Why? Please consider the following repro: public class Animal { public Animal[] Offspring { get; set; } } public class Dog : Animal {} Animal fido = new Dog { Offspring = new Animal[] { new Dog() } }; var json = JsonConvert.SerializeObject(fido, new JsonSerializerSettings { TypeNameHandling =
