From VB.net code behind when I am trying to deserialize it it's stating that
"Expecting state 'Element'.. Encountered 'Text' with name '', namespace ''."
Deserialization code snippet:
Dim serializer = New DataContractJsonSerializer(GetType(List(Of Employee))) Dim memoryStream = New MemoryStream() Dim s = msg.Content.ReadAsString() serializer.WriteObject(memoryStream, s) memoryStream.Position = 0.......
I'm in the process of deserializing a JSON object into an Entity Framework object. The property names in the JSON do not match up totally with the property names in the Entity Framework Objects. What I'd like to do is set "Name=" on the "DataContractAttribute" for the table and the "DataMemberAttribute" for the properties in the Designer.cs file. I tried setting these in the Designer.cs file manually just to see if it would work - which it did (using JSON.Net) but of course when I went into the .edmx designer I lost all my changes. Is there a way to do this?
I'm looking for a way to define and send a JSON object array. I've figured out how to define a single JSON object, turn it into a string and send it, but what about an array of this type? Probably something simple I'm overlooking...
var myColumnSetting = { "ColumnName": name, "ColumnIndex": index } convert it to a string var myJSONText = JSON.stringify(myColumnSetting, false);
I am using Json.Net however when I go to deserialize the following json I get that Json cannot deserialize to type List.
Json:
{"postalCodes":[{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10001","countryCode":"US","lng":-73.996705,"placeName":"New York City","lat":40.74838,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10019","countryCode":"US","lng":-73.985834,"placeName":"New York City","lat":40.765069,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10021","countryCode":"US","lng":-73.958805,"placeName":"New York City","lat":40.768476,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10022","countryCode":"US","lng":-73.965703,"placeName":"New York City","lat":40.757091,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10036","countryCode":"US","lng":-73.991826,"placeName":"New York City","lat":40.759724,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10065","countryCode":"US","lng":-73.96379,"placeName":"New York City","lat":40.76507,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10003","countryCode":"US","lng":-73.989223,"placeName":"New York City","lat":40.731253,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10010","countryCode":"US","lng":-73.981328,"placeName":"New York City","lat":40.737476,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10011","countryCode":"US","lng":-73.99963,"placeName":"New York City","lat":40.740225,"adminName1":"New York"},{"adminName2":"New York","adminCode2":"061","adminCode1":"NY","postalCode":"10012","countryCode":"US","lng":-73.998284,"placeName":"New York City","lat":40.72553,"adminName1":"New York"}]}
I have a custom Javascript object that has a few string and float members. I'd like to serialize an array of them in Javascript, assign the result to a hidden field, and then retrieve and deserialize them in the codebehind for my asp.net application.
I use the JavaScriptSerializer class of ASP.net to serialize my object and return it to the client side. How can I deserialize the string using JavaScript?
I've scenario where I want to insert data into database without post back. there are around 12 to 13 fields which i need to insert. I'm passing DTO from the client side which is actually Json object. Now the problem which i'm facing is how to convert that Json object which i got in webservice to the "class" (in my case class name is User) object.
[Code]....
In the above case AddNewUser method takes the object of User class. But i'm getting casting error. So how do I convert Json object to the "User" class object?
.I am using VS2010 Ultimate in an out of the box HelloWorld MVC2 ProjectI am using JQuery 1.4.1I have the following code in my View:
function TestStringArray() { var stringArray = new Array(); stringArray[0] = "item1";
[code]...
Forgetting my controller actually needs to return a Json result (I have a break on the return View() line), the values parameter is null. When I pass in a single string (change the type from List<String> to String in the controller, pass in a single string value from the View), it works fine. Looking at Fiddler, the array is passing the multiple values.I did some research and people are suggesting JSON.Stringify ion the JSON2 library, the JSON.NEt library, etc... Do I really need extra libraries? Microsoft didn't think of this scenario for out of the box? I assume the problem is any kind of complex type.
I am getting an error when trying to serialize an object products. Product product = new Product(); product.Name = "Apple"; product.Expiry = new DateTime(2008, 12, 28); product.Price = 3.99M; product.Sizes = new string[3,2] { {"Small","40"}, {"Medium","44"}, {"Large","50"} }; string json = JsonConvert.SerializeObject(product);//this line is throwing an error
Array was not a one-dimensional array. Is there any way to serialize a two dimensional array with Newtonsoft.json.
I am trying to return some data as json from an action method.
I have an employee object that looks like this:
public class Employee { public int EmployeeID {get; set;} public string FirstName {get; set;} public string LastName {get; set;} //Other irrelevant properties }
Then I have a view model as follows
public Class EmployeeViewModel { public Employee Supervisor{get; set;} public List<EmployeeViewModel> Employees }
I need to return a json object that looks exactly like this:
For now I only need to go to the second level as above, returning and supervisor and their staff members beneath them.
How would I go about returning this in my action method(I have the viewModel object hydrated already I just need to return it as json). My problem so far has been that the children property does not get populated.
Is there an easy way to populate my C# Object with the JSON object passed via AJAX?
//This is the JSON Object passed to C# WEBMETHOD from the page using JSON.stringify {"user":{"name":"asdf","teamname":"b","email":"c","players":["1","2"]}} //C# WebMetod That receives the JSON Object [WebMethod] public static void SaveTeam(Object user) { } //C# Class that represents the object structure of JSON Object passed in to the WebMethod public class User { public string name { get; set; } public string teamname { get; set; } public string email { get; set; } public Array players { get; set; } }
For some reason the following JSON string creates the correct number of records in the custom objects array, but does NOT populate the objects in the array with and values.
