    DirectMethod - how to pass an array parameter

    Hi guys,

    Let's say I want to call a DirectMethod on my JS client, passing an array of strings as one of the parameters. Something like:["arrayValue1","arrayValue2"]);
    I assumed a corresponding server-side method that receives a string array would would work and I'd get my array. However, what I actually get an array with only one element - the client-side array as a string.

    public ActionResult MyMethod(string[] arrayParameter) {
       // By inspecting arrayParameter, we get [ "[\"arrayValue1\",\"arrayValue2\"]" ]
    I found a workaround, which involves receiving the array as a string and deserializing it:

    public ActionResult MyMethod(string arrayParameterAsString) {
       var myArray = JsonConvert.DeserializeObject<string[]>(arrayParameterAsString);
       // Do stuff with parameters
    But my gut feeling tells me there's a simpler way to do this. Is there some way to tell Ext.NET that I want a parameter to be treated as an array on my server method?

    Thanks in advance!

    Hi @tcunha,

    Welcome to the Ext.NET forums!

    ASP.NET MVC manages deserialization, we don't control it.

    You can use a ModelBinder attribute.
    public ActionResult TestArray([ModelBinder(typeof(JsonModelBinder))]string[] array)

    Try to use Ext.encode

    Thanks, @Daniil! The ModelBinder did the trick!
