DirectMethod - how to pass an array parameter

[tcunha]

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:

App.direct.MyMethod(["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.

[DirectMethod]
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:

[DirectMethod]
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!
