我如何在数组中发布乘法对象并在action方法中获取数据

Question

I am using ASP.NET Core 2.1 with Web API and posting works fine when I send one object. How can I send this type here.

Until now I have tried this approach, https://ibb.co/dKztDGv , but without success. I don't get an error but I get the values from the last object only. Please help me get all the values in the array.

//I post this type of objects in array 
[
 {something...},
 {something...}
]

//what I've tried
public IActionResult PostNewLanguages([FromBody] JObject newLanguages, string id)
{
    var oneUser = GetSpecificUser(id);
    JObject class1DataJson = newLanguages;
    return Ok();
}

Answer 1

When I run this and send an array of objects I get this error

InvalidCastException: Unable to cast object of type 'Newtonsoft.Json.Linq.JArray' to type 'Newtonsoft.Json.Linq.JObject'.

So I suggest trying to send something like this instead

{ "myData": [
    {something...},
    {something...}
]}

And then to access the data you will need to do

var myValues = newLanguages["myData"];

foreach(var value in myValues)
{
}

'myData' being whatever key you use for your array. Looks like 'request' in your case going by your comments.

If you post an array of object, you need to receive it as a List like

public IActionResult PostNewLanguages([FromBody] List<JObject> newLanguages, string id)
{
    foreach(var obj in newLanguages)
    {

    }

    return Ok();
}
