c# - Json string to Array of Tuples

Question

I need to convert Json string e.g. ["value1","value2","value3","value4"] into a array of Tuples such as,

Tuple<value1,value2>
Tuple<value3,value4>

I was thinking of converting the json string into string [] and then convert it to one Tuple at a time, but wondering if there is an easy way of doing it?

Answer 1

You can use Linq as shown below:

var jArrayString = "["value1","value2","value3","value4"]";
var jArray = JArray.Parse(jArrayString);
var tuples = jArray.Select((j, index) => index % 2 == 0 
                       ? new Tuple<string, string>(jArray[index].Value<string>(), jArray[index + 1].Value<string>()) 
                       : null)
                    .Where(t => t != null);

Note - the above may not be a optimized way. the same can be done using a simple for loop :).
