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.

View 2 RepliesI'm trying to save a custom class in a session, but it just never gets saved, along with other sessions. Note that my SessionMode = STATESERVER, and i cannot change it to INPROC as per our business requirement. This is my class

What would be the best way to deserialize this
Dictionary<string, object>{
{"fName", "John"},
{"lName", "Doe"},
{"email", "john@doe.net"}
}
to this
class Member{
string fName;
string lName;
string email;
}
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.......
Here is the scenario;
1. I have a desktop application that utlizies a Binary field to store data about a quote
2. I have a Web Application that manages this program and the 50+ users.
3. This web application now stores in a SQL Database this Binary information and related information
4. I can successfully open any of these binary fields up from any of my users from my application.
5. I need the Web Application to open these up to be able to report on them, however I get the following error
Unable to find assembly '*******, Version=1.1.16.14, Culture=neutral, PublicKeyToken=null'.
Below is the code I use to serialize

Below is the code I use to deserialize
// Deserialize the quote data from the database data
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);
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"}]}
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(); }
});
I had an xml-serialization which worked fine, but as I have just knew it doesn't work in Opera browser. I think, it's security rules don't allow to write to cookies xml-content.What can I do? Can I use binary serialization or something else?
View 2 RepliesWhy to Serialize an object to store in ViewState?
View 1 RepliesI would like to serialize the properties of the HttpBrowserCapibilities object so that it may be returned via a web method call. Currently the object cannot be serialized:Cannot serialize member System.Web.Configuration.HttpCapabilitiesBase.Capabilities of type System.Collections.IDictionary, because it implements IDictionary. ...which is understandable. However, I would like to simply copy out the properties and their values to a hierarchy, i.e.
<HttpBrowserCapabilities>
<IsMobile>true</IsMobile>
</HttpBrowserCapabilities>
I'm starting to think I would need to use reflection to copy this object, but I haven't reached a conclusion. Does anyone have any suggestions to keep this simple?
I am using Flexigrid in my project to add a button on the grid toolbar I can use code like this:
"buttons":[
{"name":"Modifica","bclass":"edit","onpress":"doCommand"},
{"name":"Elimina","bclass":"delete","onpress":"doCommand"}
],
Anyway the "onpress" attribute shall contain a reference to a js callback and so this field shall not be enclosed within quotation marks.
I am using the class JavaScriptSerializer (in the System.Web.Script.Serialization namespace) to do the serialization.
How I have to declare the variable to make JavaScriptSerializer serialize like this?
"buttons":[
{"name":"Modifica","bclass":"edit","onpress":doCommand},
{"name":"Elimina","bclass":"delete","onpress":doCommand}
],
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?
View 1 RepliesLet's say I have a function that takes a string. That string contains the fully name of an enum type (e.g. "MyCompany.Area.AotherNamespace.MyEnum").
How could I create an array of strings (or List<string>) whose elements are the values of MyCompany.Area.AotherNamespace.MyEnum?
Is that even possible?I'm basically trying to serialize an enum type serverside and then output it in clientside JavaScript so I don't have to define an enum in two places--in my C# and my JavaScript.
public class Package
{
public Package()
{
name = "";
type = new List<Dictionary<string, string>>();
}
public string name { get; set; }
public List<Dictionary<string, string>> type { get; set; }
}

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);

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 have way too much javascript code to make these changes.How could I deserialize the JsonResponseItem class so I don't need the index reference in there?
