Easiest way to read from a response from URL

Question

I am new to C#, and did not find an easy piece of code to read a response from a URL. Example:

http://www.somesitehere.com/mysearch

The response is something like this ( I do not know what kind of response is this):

{ "response": {
"status": {
  "code": "0",
  "message": "Success",
  "version": "4.2"
},
  "start": 0,
  "total": 121,
  "images": [
    {
      "url": "www.someimagelinkhere.com/pic.jpg",
      "license": {
        "url": "",
        "attribution": "",
        "type": "unknown"
      }
    }
  ]
}}

After that I will to save that url "www.someimagelinkhere.com/pic.jpg" to a file. But this I know how to do. I just want to separate the url from the rest.

I saw this topic: Easiest way to read from a URL into a string in .NET

What's wrong with the solution? The page you're fetching just seems to be in JSON format... — Jwosty, Jul 29 '13 at 19:22
Link to [Json.NET](http://json.codeplex.com/). For future reference, you should look at the `Content-Type` header, which will usually tell you what the response type is. For example, this one might be something like `application/json`. — Jim Mischel, Jul 29 '13 at 21:08

Your response is of JSON Format. Use a library (NewtonSoft but there are others too) to extract the node you want.

You can use something like JSON.NET by Newton soft, which can be found and installed using NuGet Package Manager in Visual Studio.

Also you could just do this.

var jSerializer = new JavaScriptSerializer();
var result = jSerializer.DeserializeObject("YOUR JSON RESPONSE STRING");

The JSON string will not be a C# object with properties that match your names such as start, total, images, etc. If you need to you can create a strong type object and cast your converted object to that one for ease of use.

Strong typed version:

var jSerializer = new JavaScriptSerializer();
var result = (YourStrongType)jSerializer.DeserializeObject("YOUR JSON RESPONSE STRING");

var imgUrl = result.images[0].url;
