Any help would be great. Or a little clue about how to parse Json will also be enough.

What do you mean, "remotely"? What is local and what is remote in this instance? — Kieren Johnstone

What do you mean by "Parse JSON remotely"? I think your wording may be misleading if what you want to do is download a JSON string and then work with it locally... — ZombieSheep

well i just want to access this json from internet here is the link ..myhealthpal.com/charity_app/… — Burhan Mughal

You can use the JSON.Net library. Or DataContractJsonSerializer in C#. — Ravi Y

Use a brilliant Json.net library.

Features
Flexible JSON serializer for converting between .NET objects and JSON
LINQ to JSON for manually reading and writing JSON
High performance, faster than .NET's built-in JSON serializers
Write indented, easy to read JSON
Convert JSON to and from XML
Supports .NET 2, .NET 3.5, .NET 4, Silverlight and Windows Phone
The serializer is a good choice when the JSON you are reading or writing maps closely to a .NET class.

LINQ to JSON is good for situations where you are only interested in getting values from JSON, you don't have a class to serialize or deserialize to, or the JSON is radically different from your class and you need to manually read and write from your objects.

@BurhanMughal How is this answer not enough? You stated you do not know how to parse JSON, Jakub provided information regarding a popular library for doing just that, Parsing JSON.

It seems like you need to de-serialise a JSON string to an object. You can create create a class that represents the object, and then de-serialise the json to it.

Something like

class Information
{
   int id;
   string name;
   string telephone;
   // etc
}

Then de-serialise with something like this

JavaScriptSerializer json_serializer = new JavaScriptSerializer();
// Using List<T> as the JSON is organised like an array
List<Information> info = (List<Information >)json_serializer.DeserializeObject(JSONFeed);

Where JSONFeed is your json string from the website.

Are you not able to download the data? That is a different question from what you are asking.
