How can I send an array of objects to a controller in ASP.NET 6 (Core)?

edit

To send an array of objects to a controller in ASP.NET 6 (Core), you can use the [FromBody] attribute in the controller method signature. Here is an example:

1. Define the model class that represents the object in the array:

public class Item
{
    public int Id { get; set; }
    public string Name { get; set; }
}

1. Create the controller method that accepts an array of Item objects:

[HttpPost]
public IActionResult MyControllerMethod([FromBody] Item[] items)
{
    // Do something with the items array
    return Ok();
}

1. Send a POST request to the controller method with the array of items in the request body:

[
    { "id": 1, "name": "Item 1" },
    { "id": 2, "name": "Item 2" },
    { "id": 3, "name": "Item 3" }
]

Note that the Content-Type header of the request must be set to application/json to indicate that the data in the body is in JSON format.
