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.

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.......
i Want to Deserailize the follwing Json Using "foreach" loop to seperate each row from above JSON how to do it in C# ?

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
[Code]....
Below is the code I use to deserialize
// Deserialize the quote data from the database data
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));
StreamWriter myWriter = new StreamWriter(textBox1.Text);
mySerializer.Serialize(myWriter, sysinfo);
[WebMethod]
public void Reports(XmlSerializer xmlSerializer)
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(); }
});
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:

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 am facing an critical problem in Enum serialization in WCF. Here is the scenario: I have an enum like this...
[Serializable] [DataContract(Namespace = "http://www.geniusdoc.portal.com/serivces/2011/v1/GdService", Name = "AppointmentMode")] public enum AppointmentMode : int { // 1: Email, 2: Phone [EnumMember(Value = "1")] None = 1, [EnumMember(Value = "2")] Email = 2, [EnumMember(Value = "3")] Phone = 3 }
Here I decorated each enum value with [EnumMember], so that I can use the Enum as Data Contract in WCF.
And, AppointmentMode will be saved as INTEGER in database. So I need to serialize this Enum to its value. So I have specified value to each member like... [EnumMember(Value = "1")]
Problems:
If I use the above code as it is...SvcUtil not considering Enum Text, and generating the Enum in Proxy as below...
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "4.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="AppointmentMode", Namespace="http://www.geniusdoc.portal.com/serivces/2011/v1/GdService")] public enum AppointmentMode: int { [System.Runtime.Serialization.EnumMemberAttribute(Value="1")] _1 = 1, [System.Runtime.Serialization.EnumMemberAttribute(Value="2")] _2 = 2, [System.Runtime.Serialization.EnumMemberAttribute(Value="3")] _3 = 3, }
If I remove the Value from [EnumMember(Value = "1")], while deserialization is considering Enum Text, and giving results as below
<AppointmentMode>None</AppointmentMode>
Expected result:
1. Enum in the Client proxy should be same original Enum.
2. Enum Deserialization should consider EnumValue, such a way that it will return
<AppointmentMode>1</AppointmentMode>
