Can you iterate through a dictionary object that can contain a object and enum types
foreach(Dictionary<someObject, enumType> myDic in myObjects) {
if(enumType.myType == enumType.Type) {
do something here...
}
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; }
}
[code]...
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;
}

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.

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?

//C# WebMetod That receives the JSON Object

{
}
//C# Class that represents the object structure of JSON Object passed in to the WebMethod

public string email { get; set; }
public Array players { get; set; }

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.......
If I have a string containing valid JSON
how can I convert to an obect in c#?
I want to serialize an object to json, so I'm using [Code]....
[Code]....
This is fine, but I want to return different json datasets depending on the circumstances. Lets say I have this object (a simplified example):
[DataContract]
class foo
{
[DataMember] int productId
[DataMember] string productName
double price; //not used in json.. yet
}
Which will serialize to a json object containing the product name & Id, but what if I also need to be able to return a different json object (say, productId and price but not name)? Can this be done somehow in the same object using WCF/DataContracts and DataMembers? This will be sent in an ajax query containing a collection of objects and needs to fast, so just including every member in every type of json request whether it's needed or not isn't a good solution.
I have an object called MyObject that has several properties. MyList is a list of MyObject that I populate with a linq query and then I serialize MyList into json. I end up with something like this
List<MyObject> MyList = new List<MyObject>();
MyList = TheLinqQuery(TheParam);
var TheJson = new System.Web.Script.Serialization.JavaScriptSerializer();
string MyJson = TheJson.Serialize(MyList);
What I want to do is serialize only parts of MyObject. For instance, I might have Property1, Property2...Propertyn and I want MyJson to only include Property3, Property5 and Property8.
I thought of a way to do this by creating a new object with only the properties I want and from there create a new list for the serialization.
For my ASP.Net application I need to use a HTTP REST API that returns a JSON object.Here's how the JSON looks:
message: [
{
type: "message"
href: "/messages/id/23"[code]....
I could use the DataContractJsonSerializer Class and have custom Classes defined. However, am not sure how keys like "$" would get converted to in .Net.
I am unable to convert JSON string to .net object in asp.net. I am sending JSON string from client to server using hidden field (by keeping the JSON object.Tostring() in hidden field and reading the hidden field value in code behind file)
Json string/ Object:
[[{"OfferId":"1","OrderValue":"11","HostingTypeID":"3"},
{"OfferId":"1","OrderValue":"11","HostingTypeID":"3"},

{"OfferId":"1","OrderValue":"2","HostingTypeID":"3"},
[Code]....
While converting i am getting following error:
Expecting element 'root' from namespace ''.. Encountered 'None' with name '', namespace ''.
I have a json object collection of geo locations that I build in the server. Each of those objects has two properties: "marker" and "onClick". Marker is for storing a Google Maps marker object and the onClick stores the name of the function to be called when that marker is clicked on the map.When I'm pushing the location objects into an array using javascript in the client side, I create the markers and assign them to each location object within the array.
My problem is that when I bind the marker with the onClick property, the function won't be found in the DOM and get an error.Is there a way to declare a property in a json object for using it on an event binding?
