Advanced VB.NET Programming – Serializing Objects with JSON

Vb net newtonsoft json linq jobject

Represents a JSON object. Tries to get the JToken with the specified property name. The exact property name will be searched for first and if no matching property is found then the StringComparison will be used to match a property. The last option is to create a JSON object from a non-JSON type using the FromObject () method. Internally, FromObject will use the JsonSerializer to serialize the object to LINQ to JSON objects instead of text. The example below shows creating a JSON object from an anonymous object, but any .NET type can be used with FromObject to create JSON.Dim jsonArray As JArray = jsonObject("result") For Each item As JObject In jsonArray. textboxLast.Text = item.SelectToken("Last").ToString. Next. It has to do with the format of the JSON. it is not an array, but an object that contains an array, so you have to first parse the object, and then take the array out of it to parse properly. Dim parsejson As JObject = JObject.Parse(json) ' THIS LINE GIVES THE ERROR Dim thename = parsejson.SelectToken( "data.name" ).ToString() txt1. Text = "Name Is " + thename. End Sub End Class. Parsing the JSON from the link in the code. (Broken into lines to fit code better) Here is the actual JSON link. string json = @"{ CPU: 'Intel', Drives: [ 'DVD read/writer', '500 gigabyte hard drive' ] }"; JObject o = JObject.Parse(json); Newtonsoft.Json | Test your C# code online with .NET Fiddle code editor. SelectToken is a method on JToken and takes a string path to a child token. SelectToken returns the child token or a null reference if a token couldn't be found at the path's location. The path is made up of property names and array indexes separated by periods, e.g. Manufacturers [0].Name. 'Stores': [.
