convert json string to string array

Question

I'm trying to convert a json string to a string array

my json string: "[\\"false\\",\\"true\\"]"

var js = new System.Web.Script.Serialization.JavaScriptSerializer();
string[] strArray = new string[2];
strArray = js.Deserialize("[\"false\",\"true\"]", string[2]).ToArray();

but it only allows me to do a charArray.

I just need to be able to call my result as strArray[0] so that it will return "false"

Answer 1

尝试做：

strArray = js.Deserialize<string[]>("[\"false\",\"true\"]");

Answer 2

Your example code wouldn't compile. The second parameter should be a Type object, which string[2] isn't. It should be this:

strArray = js.Deserialize("[\"false\",\"true\"]", typeof(string[]));

Or, as the other answer mentioned, you can use the other, generic overload for the method:

strArray = js.Deserialize<string[]>("[\"false\",\"true\"]");

Either one will do exactly the same thing. It's just handy to be able to pass a Type object sometimes if you don't know beforehand what the actual type will be. In this case you do, so it doesn't matter.

Answer 3

Why not use Newtonsoft's JArray type? It is built for this conversion and can handle many edge cases automatically.

var jArray = JArray.Parse("[\"false\",\"true\"]");
var strArray = jArray.ToObject<string[]>()

This will give you a string array. But you could also elect to use .ToArray() to convert to a JToken array which can sometimes be more useful.
