![]() Var json = JsonConvert. All of the code used so far in this tutorial have provided data for the DataSource of the grid which ends up serializing all the data as JSON into the HTML page. I've tried the following code instead of the code above: public IQueryable GetGroups() I don't know how to use Newtonsoft.Json to serialize the table with the content in JSON format. Ĭontroller: private EfContext db = new EfContext() Json Conversion, uses DataContractJsonSerializer to deserialize item. When I use the code below I'm getting an error when I type. This is extension method for format the data time into the string with pattern. ![]() ![]() The database and the tables with content are even created. I'm using WebAPI 2 and Entity Framework 6. I have even used this approach to implement a protobuf-net version for even greater speed and reduced payload.I have a problem with Serialization of Data from database to JSON format. Web API serializes the IQueryable interface just fine as an array.You should be able to see in fiddler now that we have issued a request in each format (Xml and Json) and received the appropriate format in your response. Because JSON is the default format for Web API, its easy to access data from the. For example, if my Web API controller looks like this: public class PeopleController : ApiController ", item.LastName) Ĭonsole.WriteLine("-") Īnd weâre done. One of the features that excites me about Web Api is the ability to expose an IQueryable on a Rest service and have Web Api automatically map queries in oData uri format to actual linq queries on the source i expose. ![]() Deserialize (Stream, Type, Json Serializer Context) Reads the UTF-8 encoded text representing a single JSON value into a returnType. Using ASP.Net Web Api instead of WCF Data Services Deserialize (Read Only Span, Type, Json Serializer Options) Parses the text representing a single JSON value into an instance of a specified type.![]() This topic demonstrates how to serialize.NET type objects into JSON-encoded data and then deserialize data in the JSON format back into. Lots of people have already talked about the benefits of the Web API and how it has been built with simplicity, transparency, extensibility and testability in mind so Iâll not go into too many details about that here. Specifically to your second function, JsonConvert.SerializeObject would just serialize any object into a JSON format string, which means you should return a string instead of an IQueryable. The ASP.Net MVC4 Beta was released recently and included the Beta release of ASP.Net Web API, formally known as the WCF Web API. CONCATENATE ââ name ââ ccolon INTO lvalue.CLTREXJSONSERIALIZER doesnât put the attribute in double quotes. TL DR: How to create a client Linq api for querying IQueryable ASP.Net Web API rest services in very few lines of code using JSON.Net and Linq2Rest. 1 There is a space that causes arithmetic problems, at the end of the converted numeric values. ![]()
