It’s doable; this works but it’s not elegant. I’m sure there’s a better way. var o = JObject.Parse(yourJsonString); foreach (JToken child in o.Children()) { foreach (JToken grandChild in child) { foreach (JToken grandGrandChild in grandChild) { var property = grandGrandChild as JProperty; if (property != null) { Console.WriteLine(property.Name + “:” + property.Value); } } } … Read more
Douglas Crockford posted a comment on this Google+ post which helped me start to clarify things: JSON is just a grammar, and the grammar includes numbers and strings. Uses of JSON must necessarily be more restrictive. RFC-4627 is one possible use, and was never intended to be the standard for JSON itself. We cannot say … Read more
According to this msdn link, DateTime objects are… …represented in JSON as “/Date(number of ticks)/”. The number of ticks is a positive or negative long value that indicates the number of ticks (milliseconds) that have elapsed since midnight 01 January, 1970 UTC. So you are correct that .NET assumes, but it’s UTC instead of GMT … Read more
As of Json.NET 6.0 Release 3 and later (I tested on 8.0.3), this works automatically as long as the custom class implementing IEnumerable<MyType> has a constructor that takes an IEnumerable<MyType> input argument. From the release notes: To all future creators of immutable .NET collections: If your collection of T has a constructor that takes IEnumerable … Read more
0x1fffffe8 is exactly 512MB. The many commenters are correct: you are bumping up against a system limit. I agree with @Pointy that it is mostly likely a Node string length limit. fs-extra has nothing to do with the limit In any case, you’re going to have to process that JSON in chunks. Below are different … Read more
Annotations-only approach Alternatively to the custom deserializer approach, you can have the following for an annotations-only solution (similar to the one described in Spunc’s answer, but using type as an external property): public abstract class AbstractData { private Owner owner; private Metadata metadata; // Getters and setters } public static final class FooData extends AbstractData … Read more
Thanks but getting 405 error,after the above config changes. Finally it works after adding below code in web api Global.asax file protected void Application_BeginRequest(Object sender, EventArgs e) { //HttpContext.Current.Response.AddHeader(“Access-Control-Allow-Origin”, “*”); if (HttpContext.Current.Request.HttpMethod == “OPTIONS”) { HttpContext.Current.Response.AddHeader(“Cache-Control”, “no-cache”); HttpContext.Current.Response.AddHeader(“Access-Control-Allow-Methods”, “GET, POST”); HttpContext.Current.Response.AddHeader(“Access-Control-Allow-Headers”, “Content-Type, Accept”); HttpContext.Current.Response.AddHeader(“Access-Control-Max-Age”, “1728000”); HttpContext.Current.Response.End(); } }
img_url is not a property of root object – it’s a property of data object: var obj = JObject.Parse(json); var url = (string)obj[“data”][“img_url”]; // http://s1.uploads.im/D9Y3z.png Another option: var url = (string)obj.SelectToken(“data.img_url”);
It should be: var str=”[{“Company”: “XYZ”,”Description”: “\\”TEST\\””}]”; First, I changed the outer quotes to single quotes, so they won’t conflict with the inner quotes. Then I put backslash before the innermost quotes around TEST, to escape them. And I escaped the backslash so that it will be treated literally. You can get the same result … Read more
