How to call a POST method with multiple parameters?

I'm building a MVC project and I have some problems to send the data from my view to the controller or apicontroller. I need to call a POST method in the apicontroller with the parameters or the object;

string fname = "Mark"; 
string lname  = "Twain";
string address = "Some street";

or

An instance of the class Person.

  1. How can I send multiple parameters or an object?
  2. Should I send it direct to the apicontroller or send it the original controller? I have both a Studentcontroller and an StudentInfocontroller : apicontroller
  3. Should I use Html.ActionLink or JavaScript $.post?

You could use a post or many other ways to get the data, but if it's a form and you are using asp.net, Razor handles that for you. Html.BeginForm assumes you have a model that will be updated by the user via texboxes or other controls. Then some button click will do the call. Notice <button type="submit"> tells the form that when the button is pressed the service is to be called and the model object is posted.

This answer is the bare bones of using Html.BeginForm. You will need to dig a little deeper to get a good understanding.

@model Student
@using (Html.BeginForm("InsertStudent", "StudentInfocontroller"))
{
   // style it appropriately
   @Html.TextBoxFor(m => m.fName)
   @Html.TextBoxFor(m => m.lName)
   <button type="submit" class="btn">Submit</button>
}

Controller call.

[Route("InsertStudent")]
public async Task<IActionResult> InsertStudent(Student student)
{
   // do something with the student object received. Like insert or update the database.

   Repository.InsertOrUpdate(student); // assuming you have a repository.

   return View("Confirmation", student); <--- let the user know?
}
