How to convert JavaScript (Node.js) array into C# string Array?

Question

I created an array and I want to send it to a C# application. I want to be able to use it as a C# string array so I can create a for loop where I can run some tasks.

Node.js (Express.js)

router.get('/arr', function(req,res,next) { var arr = ["orange", "plum", "strawberry", "lemon", "tangerine"]; res.send(arr); }); 

C# code.

public string Arr() { HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://10.0.2.2/arr"); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); StreamReader stream = new StreamReader(response.GetResponseStream()); string final_response = stream.ReadToEnd(); stream.Dispose(); return final_response; } 

C# application's editor (This is an editor where I can do very limited stuff, so there's no way to import 3rd party packages but you can do basic stuff like http get/post, etc)

string Answer = Lib.Arr(); 

How can I create Answer as a string array? I tried creating Answer as string[] Answer but it says string can't get converted into string[], where am I wrong?

I'm new to C#.

If all you need to parse is an array of strings, then you can do something like this:

string trimmedAnswer = Lib.Arr().Trim(); // Remove whitespaces from the beginning and end trimmedAnswer = trimmedAnswer.Substring(1, trimmedAnswer.Length - 1); // Remove [ and ] characters string[] Answer = trimmedAnswer.Split(",").Select(s => s.Trim()).ToArray(); // Split every element by the commas, and remove any whitespaces 

But if you need to parse more complicated jsons, then you need something like this answer: https://stackoverflow.com/a/24891561/2420998
