No, this string is not in Json format It's only in string format @RishabhKumar — RAJNIK PATEL, Nov 14 '16 at 04:52
Can you show us part of the big string that you have as an example? — Ibrahim, Nov 14 '16 at 05:10
please see edited question for output which i want from big string @Ibrahim — RAJNIK PATEL, Nov 14 '16 at 05:14
This looks to me like a Json string with escaped characters... does the string actually contain sequences like `\"`, or is it just the debugger display? — vesan, Nov 14 '16 at 05:14
Where do you get this string from? An api call? This surely does look like a valid json, and it parses correctly. — Mat J, Nov 14 '16 at 05:20
Hey @RAJNIKPATEL did u tried my solution. :) Give it a try. U might like it. — Mohit S, Nov 15 '16 at 01:40
@MohitShrivastava Mr. Ibrahim's code working well and using that code solved my problem. So, I haven't tried any more code — RAJNIK PATEL, Nov 15 '16 at 04:35

If you just need .jpg file name, you can try this simple Regex:

\w+\.jpg

Demo: https://regex101.com/r/KMWtZY/1

You can use it with C# as follows:

var regex = new Regex(@"\w+\.jpg");
return regex.Matches(strInput);

You should escape "." character. Your regex also matches 2ff1_jpg, asdasd,jpg – Renat Zamaletdinov Nov 14 '16 at 05:21
@RenatZamaletdinov Thanks, I updated my answer and escaped "." – Ibrahim Nov 14 '16 at 05:27

Your string seems like it is a JSON String. and thus it would be easier and convienent approach to desealize the JSON into an object and fetch the values like

Create a class for the Object of your JSON String

public class YourData
{
    public string url { get; set; }
    public string href { get; set; }
    public string filename { get; set; }
    public string url_master { get; set; }
    public string path_master { get; set; }
    public string data_center { get; set; }
    public string menu_type { get; set; }
    public string title { get; set; }
    public string menu_type_class { get; set; }
    public string real_menu_type { get; set; }
    public int is_salt_special_menu { get; set; }
    public string start_date { get; set; }
    public int consumer_upload { get; set; }
    public string start_date_formatted { get; set; }
    public string end_date { get; set; }
    public string end_date_formatted { get; set; }
    public int id { get; set; }
}

Than

//From wherever you are reading it.
string jsonstr = "Your Json String";
//I Removed all the / and \ from the string
jsonstr = jsonstr.Replace("/", "");
jsonstr = jsonstr.Replace("\\", "");
//at last of the string you have something like this 
//;\n        .menuTypes = [\"DEFAULT\",\"FOOD\",\"BAR\",\"DELIVERY\",\"SPECIAL\",\"TAKEAWAY\",\"INTERNAL\"];\n
//which is not the part of the JSON string. So I removed that part as well to make it a valid JSON
jsonstr = jsonstr.Remove(jsonstr.IndexOf(";n"));
//Console.WriteLine(jsonstr); //You can uncomment it to see how JSON looks after cleaning.
//Just Deserialize the JSON
List<YourData> yd = JsonConvert.DeserializeObject<List<YourData>>(jsonstr);
//Loop to get all the filenames or any other fields you want 
foreach(YourData ydd in yd)
{
    Console.WriteLine(ydd.filename);
}
