i Want to Deserailize the follwing Json Using "foreach" loop to seperate each row from above JSON how to do it in C# ?
{ "Data":[ {
"id":"1", "Name":"Sachin" }, {
"id":"2", "Name":"Rahul" }, {
"id":"3", "Name":"Sovrav" } ]}
We are trying to consume WCF service which returns employee details in JSON Format.
like:
{"d":[{"_type":"Employee:#","BigThumbNailURI":null,"ID":1,"Name":"E1"},{"_type":"Employee:#","BigThumbNailURI":null,"ID":2,"Name":"E1"}]}
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.......
public class SocialFriends
{
public string id { get; set; }
public string name { get; set; }
}
this is my Class.
List<SocialFriends> oList2 = ser.Deserialize<List<SocialFriends>>(response.Content);
I'm getting data's like this. But it returns 0 data :S
Data is here
{"data":[{"name":"George","id":"511222445"},{"name":"Mayk","id":"517247768"}]}
Wondering how to deserialize the following string in c#:
"[{"access_token":"thisistheaccesstoken"}]"
I know how to do it if the json was:
"{array=[{"access_token":"thisistheaccesstoken"}]}"
I'd do it like this:
public class AccessToken
{
public string access_token {get;set;}
public DateTime expires { get; set; }
}
public class TokenReturn
{
public List<AccessToken> tokens { get; set; }
}
JavaScriptSerializer ser = new JavaScriptSerializer();
TokenReturn result = ser.Deserialize<TokenReturn>(responseFromServer);
I am using Json.Net however when I go to deserialize the following json I get that Json cannot deserialize to type List.
Json:

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?

The serialized string build a JSON like this
{ "person.name": "??", "person.age": "??", "person.address.street": "??" }
I need a plugin or some function to generate like this:

View 3 RepliesI have a text file named gisQuery129.json that is created using Json.NET - [URL] There is an example on how to create a JSON file and I have done that successfully, but I want to read the file on a page load event and add the values to .NET textbox controls for input values in a query. The created file looks like the following:
{
"myData": {
"randomNumber": "129",
"Application": "MyMapApp",
"FeatureId": "ALL",
"Feature": "ALL",
"spatialQuery": "FEATURE_ID= '11111' AND REQ_SEQ_NUM= 1 AND RAND_PARAM= 129 OR FEATURE_ID= '22222' AND REQ_SEQ_NUM= 2 AND RAND_PARAM= 129"
}
}
I want to read the data in the above sample JSON data and then populate my textboxes something like this:
txtRandParam.text = "129"
txtApplication.text = "MyMapApp" and three more text boxes after that.
to be able to send a XmlSerializer class (which is generated obvious in remote C# application) over a WebService that will then deserialize it into a class. (I didnt know it its possible either)
XmlSerializer mySerializer = new XmlSerializer(typeof(SystemInfo));

mySerializer.Serialize(myWriter, sysinfo);

I've been struggling with this issue for a while. I'm trying to send an object to the client. Once the client updates the object I'd like to post it back to the server and save it in my database. The first part works fine. However, when I send it back all the dates are messed up and start for year 0001. I assume that's because it can't deserialize the date. Howe can I post a json object with a date property and deserialize it into a type on the server with asp.net mvc 3? group is
public class Group
{
public Group();
public string CreatedBy { get; set; }
public DateTime CreatedOn { get; set; }
public string Description { get; set; }
public string Name{ get; set; }
public string Status { get; set; }
public string UpdatedBy { get; set; }
public DateTime UpdatedOn { get; set; }
}
while
public JsonResult updateGroup(Group group)
{
var result = Repository.updateGroup(group);
return Json(result, JsonRequestBehavior.AllowGet);
}
and on the client I got
$.ajax({
url: '../updateGroup',
type: 'POST',
data: JSON.stringify(group),
dataType: 'json',
contentType: 'application/json; charset=utf-8',
success: function(){ success(); }
});

It deserializes it so I have to reference everything by index first, because of the list. So if I had a property called "IsValid" I would have to reference it like this "IsValid[0]".

I've been tasked with implementing a JSON feed on an asp.net website that will be consumed by 3rd party apps (such as IPhone, Android, etc) and I'd like to follow best practices.
An example of what I'd like to achieve would be something similar to: [URL]
I've chosen the JSON.net api as this seems to be highly recommended.
My Google-fu must be failing me as I can't find a single full example code for an Asp.net web application with JSON.net implemented on it, so I've no real concept of where to begin.
My question is fairly simple:
Should I create this sort of feed as an ASPX, or ASHX file? Or even a .NET Web Service? (Remember that the tools that will be using this feed are on external apps like IPhones, etc)
I created a test feed in both ASHX and ASPX format ... here is the code (I'm using Subsonic to populate the collection) ... are either of these along the correct lines?

I am trying to figure out how to send an image to Tuzulo using their api which appears to use JSON (quoted below). I have figured out how to receive information about what images I have with them and their URLs but cannot figure out how to send an image.
I have found lots of JSON examples but they all seem to show sending or receiving strings. Could someone give me a hint?
[URL]
Private API URLs These URLs require private keys, used for management and extension. To protect each upload, the private key must be known (saved, bookmarked, etc.). With an account, this becomes transparent.
[Code]....
<private-key>
Extend collection.
[Code]....
<private-key>
Manage collection.
Public keys are meant to be shared while private keys are meant to be temporarily bookmarked if necessary. Bookmarking is unnecessary when you're a site member.
