Is there any possibility to map array from url?

Can I convert this url:

http://localhost:4200/api/hoursRange=[0,12]

to int[] HoursRange? I'm using ASP.NET Core 2.2

I tried this code:

[HttpGet]
[Route("api")]
public IActionResult Get([FromQuery]int[] HoursRange)
{
    // action
}

but it doesn't work.

Solution 1: The default model binder expects this url:

http://localhost:4200/api/hoursRange=1&hoursRange=2&hoursRange=3

Only work for this type of method: 

[HttpGet]
[Route("api")]
public IActionResult Get([FromQuery]int[] HoursRange)
{
    // action
}

Solution 2: to do that but in different method but in asp.net mvc

Need to change method name like this 

http://localhost:54119/api/MultipleData?ids=24041&ids=24117

in order to successfully bind to:

[HttpGet]
[Route("api")]
public ActionResult MultipleData(int[] ids)
{
    ...
}

Solution 3: For another verified solution check link

Solution 4: indexer is also one way to do but not an efficient way 

http://localhost:4200/api/hoursRange[0]=24041&hoursRange[1]=24117&hoursRange[2]=24117

Please take a look at the title Collections in Model Binding

It shows several ways in which this can be achieved.

A couple of the ways shown in the Microsoft documentation are:

hoursRange=0&hoursRange=12

Using an indexer

hoursRange[0]=0&hoursRange[1]=12
