Is there any possibility to map array from url?

Question

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.

Receive it as text, and then parse it into an array. Pretty simple, really; all you have to do is strip off the brackets and do a split on the comma. — Robert Harvey, Nov 14 '19 at 17:46
if you could change the url to `http://localhost:4200/api/hoursRange=0&hoursRange=12`, it could work — Matt.G, Nov 14 '19 at 17:57

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

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
