Passing Array from Javascript to C#

I have a .js script that contain an array:

The output of the js is like:

var foo=
[
    {
        "bar1":"value1",
        "bar2":"value2"
        // And so on...            
    }
]

I have no access to the js source, so i cannot output as JSON and Deserialize.

I can only get this as a String using WebClient, but how i can parse it and create an Array/Dictionary and work on it inside C#?

You can use a JavaScriptSerializer to deserialize that string:

string str=
@"var foo = 
  [
    {
        ""bar1"":""value1"",
        ""bar2"":""value2""

    }
]";

JavaScriptSerializer js = new JavaScriptSerializer();
var o = js.Deserialize<Dictionary<string,string>[]>(str.Substring(str.IndexOf('[')));

Result:

Dictionary<String,String> (2 items)   

Key    Value 
------ --------
bar1   value1 
bar2   value2

var foo = new JavaScriptSerializer().Deserialize<List<YourModelHere>>(YourString);

You should consider calling WebClient.DownloadString . Then Parse using JSON.Net or whatever

As per the example provided over there 

string json = @"{
  ""Name"": ""Apple"",
  ""Expiry"": "2008-12-28T00:00:00",
  ""Price"": 3.99,
  ""Sizes"": [
    ""Small"",
    ""Medium"",
    ""Large""
  ]

}";
JObject o = JObject.Parse(json);
string name = (string)o["Name"];
// Apple
JArray sizes = (JArray)o["Sizes"];
string smallest = (string)sizes[0];

// Small
