javascriptserializer

问题 Ok so I'm trying to use the JavaScriptSerializer to work with this code. However it crashes when it reaches the last line; Dim json As New String(sr.Serialize(dt)) I get this error message; A circular reference was detected while serializing an object of type 'System.Reflection.Module'. I would really appreciate any insights that could help solve this problem. 回答1: Circular reference means that serialising the object would result in an infinite loop. For example if you would try to serialize

问题 I have a js object structured like: object.property1 = "some string"; object.property2 = "some string"; object.property3.property1 = "some string"; object.property3.property2 = "some string"; object.property3.property2 = "some string"; i'm using JSON.stringify(object) to pass this with ajax request. When i try to deserialize this using JavaScriptSerializer.Deserialize as a Dictionary i get the following error: No parameterless constructor defined for type of 'System.String'. This exact same

问题 I am trying to use JavaScriptSerializer in my application. I initially received Cannot find JavaScriptSerializer and I solved it by adding: using System.Web.Script.Serialization; But then the sub-keyword Script is underlined with a blue line: The type or namespace 'Script' does not exist in the namespace 'System.Web' (are you missing an assembly reference?) So I added to the project a reference to: C:\Program Files (x86)\Reference Assemblies\Microsoft\Framework.NETFramework\v4.0\System.Web

问题 I have a data table in my database where I store various settings. Since they are of any type (even complex object graphs) I decided to store their values as serialized JSON strings. Let's say that I serialized a List<ItemBase> . Serialized string looks just fine. But the problem is that list items are of various types that are inherited from ItemBase (which may as well be abstract for what I care). Question Which (de)serialization class/library should I use so my JSON strings will be

问题 here's my problem: I'm trying to deserialize json that hasn't been done by me. The format of the json is as follows: {"responseId":1200, "availableHotels":[ {"processId":"HA-84665605","hotelCode":"UKKTLT","availabilityStatus":"InstantConfirmation",...}, {"processId":"HA-28600965","hotelCode":"UKKTLT","availabilityStatus":"InstantConfirmation",...}, {"processId":"HI-63991185","hotelCode":"UKJOVF","availabilityStatus":"InstantConfirmation",...} ], "totalFound":9, "searchId":"TP-84026455"} And

问题 I have an asp.net-mvc website and i am reading in Json string from a Database. Here is the following json in a DB. It could look like this: {"description": "Test", "contacts": ["joe@gmail.com", "bill@yahoo.com"], "enabled": true} or this: {"description": "Test", "contacts": "joe@gmail.com, bill@yahoo.com", "enabled": true} so as you can see, the contacts field is either: a string (with items separated by commas) an array of strings. I want to convert to this class: public class MyJob { public

问题 I have this C# object: var obj = new { username = "andrey", callback = "function(self) { return function() {self.doSomething()} (this) }" } I need to JSON serialize it to pass to the browser in ajax call. I use JavascriptSerializer, but it serializes to the following JSON: {"username":"andrey", "callback": "function(self) { return function() {self.doSomething()} (this) }"} but what I need is: {"username":"andrey", "callback": function(self) { return function() {self.doSomething()} (this) }}

问题 I have a class public class Money { public string Currency { get; set; } public decimal Amount { get; set; } } and would like to serialize it to JSON. If I use the JavaScriptSerializer I get {"Currency":"USD","Amount":100.31000} Because of the API I have to conform to needs JSON amounts with maximum two decimal places, I feel it should be possible to somehow alter the way the JavaScriptSerializer serializes a decimal field, but I can't find out how. There is the SimpleTypeResolver you can

问题 Note: I posted a similar question, which was the ancestor of this question, as I was originally thinking of using JSON.NET to parse the JSON, but I'm using the built-in deserializer, so it's a different question. This is what I'm trying to do: I have a class called Item, for example. The json has many "elements" (if that's what they are called - they mimic the Item class), and each contains 3 fields: an integer named id, a string named name, and a datetime named creationTime. I would like to
