How can I parse the elements of an array in a Json string using DataContractJsonSerializer? The syntax is:
{
"array":[
{
"elementsProperies":"SomeLiteral"
}
]
}

You wouldn't necessarily "parse" a json string using DataContractJsonSerializer, but you can deserialize it into an object or list of objects using this. Here is a simple way to deserialize it to a list of objects if this is what you're after.
First you need to have an object type you plan on deserializing to:
[DataContract]
public class MyElement
{
[DataMember(Name="elementsProperties")] // this must match the json property name
public string ElementsProperties { get; set; }
}
You can then use something like the following method to deserialize your json string to a list of objects
private List<MyElement> ReadToObject(string json)
{
var deserializedElements = new List<MyElement>();
using(var ms = new MemoryStream(Encoding.UTF8.GetBytes(json)))
{
var ser = new DataContractJsonSerializer(deserializedElements.GetType());
deserializedElements = ser.ReadObject(ms) as List<MyElement>;
}
return deserializedUsers;
}

you can also look into other json deserializers like json.net

thanks a bunch =D I already found the "solution" though. ( and idd, I used the deserialize method =3 ) What I did, with my retard head, is giving both the List in which to store the data, and also the element that I wanted to store the [DataContract] prefix. ( I started with just the element but only later decided to use a List to store data, and forgot about the [DataContract]. I'm sorry, but forgot to delete the question. ( should I, or should I keep it for future reference? )
I suggest using Json.net.
In it you would just call:
var jsonObj = JObject.Parse(yourjsonstring);
var elPropertyValue = (string)jsonObj.SelectToken("array[0].elementsProperies");
to get the "SomeLiteral".
