问题 Trying to serialize/deserialize an Action<>. Try #1 naive by me JsonConvert.SerializeObject(myAction); ...

问题 I have a controller method with the following signature [HttpGet] [Route("results")] public List<IResult> GetResults() { return repo.GetResults(); } Not surprisingly, I get a JSON .NET exception saying JSON .NET can't resolve IResult to a concrete type. Is there a way to provide JSON .NET the concrete class (Result) so I don't have to change the singature of the method? 回答1: It seems like what you want to do isn't really dependency injection but instead you want to control how the data is

问题 I have the following example response provided in JSON. I'd like to be able to convert this to a C# DataTable so I can loop through the elements and program on from there. { "totalItems" : 10, "pageSize" : 20, "page" : 1, "items" : [ { "type" : "call", "uri" : "http://link.com", "created" : "2014-07-28T10:02:48.000+0000", "callType" : "external", "from" : "01234567891", "to" : "01234567892", "callId" : "ast01-1406541749.604847", "links" : { "recordings" : "http://link.com" } }, { "type" :

问题 I am trying to find a way to both serialize and deserialize a dataset with one datatable to JSON and from JSON back to a dataset / datatable using JSON.NET, however all the samples and examples I have found are only serializing from a dataset or datatable to JSON and never two way. We have a system that deals with XML serialized datasets and datatables that we need to still retain in that format but allow certain UI views to render the data as JSON. Data can have null values and that's valid.

问题 Given the following code: [JsonIgnore] [Display(Name = "Loan Cap")] public virtual string SomeProperty { get; protected set; } When the DataAnnotationsModelMetadataProvider.CreateMetadata is called by ASP.NET MVC to fulfil the following call: @Html.DisplayNameFor(model => model.SomeAttribute) The list of attributes handed to CreateMetadata does not include the [Display] attribute (or the [JsonIgnore] for that matter). If I remove the [JsonIgnore] then the [Display] gets found and passed to

问题 I am trying to deserialize a field: "presenters":[{...},{...}] but some of the rows come back with only: "presenters":"" When the serializer gets to the row with that empty string I get: Error converting value "" to type 'System.Collections.Generic.List`1[DataPrototype.Model.Presenter]'.

If it is a string then

问题 Using Newtonsoft's .Net Library to convert JSON to XML, is there a way to convert a specific JSON element to an XML attribute? For example, taking the following JSON: { "array": { "item": [ 1, 2, 3 ], "length": 3 } } and converting it to: <array length="3"> <item>1</item> <item>2</item> <item>3</item> </array> Thanks. 回答1: Can you prefix the attributes with @ and put them at the top of the object? It says in the docs: Attributes are prefixed with an @ and should be at the start of the object.
