How to set up serialization of request parameters?

Question

ASP.NET

Good afternoon, the problem is this:
there is a model for adding something:

public class Person
{
     public int Id { get; set; }
     public int Name { get; set; }
     public IEnumerable<Tag> Tags{ get; set; }
}

public class Tag
{
     public int Id { get; set; }
     public int Name { get; set; }
}

and there is a submit form of this model

@using (Ajax.BeginForm("AddFoo", "MyController", new AjaxOptions { UpdateTargetId = myId, HttpMethod = "POST", InsertionMode = InsertionMode.ReplaceWith }))
{
...
}

The problem is that the Tags field is not passed, apparently ToString() is simply called for it and in the request it looks like Tags=System.Collections.Generic.List....
How to fix this? Maybe I'm doing something wrong?

Answer 1

in the HTML code inside the form it should be some kind of input with the names
"Tags[0].Id"
"Tags[0].Name"
"Tags[1].Id"
"Tags[1].Name"

Answer 2

I think that you do not have a field for Tags on the form. If you do not need to enter data manually for Tags on the form, then make it hidden, but initialize it with the data that you want to receive when receiving data from the form.
