How to deserialize the json string with multiple values

So inline it will be difficult for you to bind the lowest value here:-

In my view you may try two ideas here as listed below:

1) Put a separate calculated property which will contain the value for lowest fares and bind that field to the label text. OR

2) Go for calling a separate method which will take the entire text and return you the lowest fare and which you can bind inline.

Some sample code might look like below:-

<asp:label id="Label1" runat="server" xmlns:asp="#unknown"><![CDATA[<%= GetMyText("comma separated fares") %></asp:label>

protected string GetMyText(string input)
        {
            string output = string.Empty;
            // calculate the lowest from the comma separated input value and store in variable "output"
            return output;
        }

Hope this will be of help to give some hint.
