i using json first time , after search in internet found json.net. thought easy use have problem it. every time use code warning:
cannot deserialize current json array (e.g. [1,2,3]) type 'json_web_api.machine' because type requires json object (e.g. {"name":"value"}) deserialize correctly.
this json array url:
[ { "id": "machinetool 1", "guid": "not implemented", "name": "individueller maschinenname", }, { "id": "machinetool 2", "guid": "not implemented", "name": "individueller maschinenname", } ] and code:
using system; using system.collections.generic; using system.linq; using system.text; using system.threading.tasks; using system.net; using system.runtime.serialization; using newtonsoft.json; namespace json_web_api { class program { static void main() { string json = new webclient().downloadstring("http://localhost:12084/machines?format=json"); console.writeline(json); //string json = @"[{"id":"machinetool 1","guid":"not implemented","name":"individueller maschinenname"},{"id":"machinetool 2","guid":"not implemented","name":"individueller maschinenname"}] //console.writeline(json)"; machine machine = jsonconvert.deserializeobject<machine>(json); console.writeline(machine.id); console.read(); } } [datacontract] class machine { [datamember] internal string id { get; set; } [datamember] internal string guid { get; set; } [datamember] internal string name { get; set; } } }
convert list of machine
var machine = jsonconvert.deserializeobject<list<machine>>(json); to access data run foreach on machine.
foreach(var data in machine ) { console.writeline(data.id); }
