如何使用与Windows应用商店应用兼容的命名空间将JSON字符串转换为本机C＃数组？

Question

I am trying to make a windows 8 Store app that gets results from a MySQL database from a PHP page as a REST service.

I'm looking for the PHP to return a JSON representation of an array of strings and have done that happily when dong the same between Javascript and PHP. I need to take that same JSON string and use it in my C# Windows 8 store App, is there a way to take the return of that PHP page and convert it into a normal C# array, not a dictionary or more complex collection.

The database does have four fields so if i have to use a special object made for this i will, but I'd rather I didn't as this function doesn't require that amount of data.

The PHP page is like so - $search_text is passed in via a GET:

$databaseConnection = new mysqli(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);
    if ($databaseConnection->connect_error)
    {
        echo "Database connection failed: $databaseConnection->connect_error";
    }
    else
    {
        $search_text = $search_text."%";
        $query = "SELECT DISTINCT street FROM gritroutes WHERE street LIKE ? LIMIT 5";
        $statement = $databaseConnection->prepare($query);
        $statement->bind_param('s', $search_text);
        $statement->execute();
        $statement->store_result();
        $statement->bind_result($street);
        $autonumber = 1;
         while ($statement->fetch())
         {          
             $resultarr[] = $street;
         }
         $statement->close();
         echo json_encode($resultarr);
    }

Just to be clear. I am writing a Windows Store App, the System.Web Namespace is unavailable so i can't use JavaScriptSerializer.

Answer 1

Just to add to Matthew's answer, you can deserialize using Json.NET (you can get it from NuGet ), you'd do something like:

List<string> myStrings = JsonConvert.DeserializeObject<List<string>>(myJson);

This is in:

using Newtonsoft.Json;

Check out this article for practical example.

EDIT - I'd also like to throw in this link , since it's just awesome.

I hope this helps.

Take a look at the JavaScriptSerializer class.

string myJson = "{blablabla I'm json}";
var serializer = new JavaScriptSerializer();

var myStrings = serializer.Deserialize<List<string>>(myJson);

foreach (var str in myString)
{
    Console.WriteLine(str);
}

You could also use native Windows.Data.Json classes to do the parsing:

string json = @"[""item1"", ""item2"", ""item3""]";
var array = JsonArray.Parse(json).Select(i => i.GetString()).ToArray();
