Send values from a view with a post and getting them in another view

I'm starting with ASP.net MVC, and I have two views. The first one is ViewPost, with a form, which I want that when pressed the input button, will send the info from the form to another view. My code is like this:

<h2>ViewPost</h2>
<form method="POST" action="~/Home/NewView">
    Number<input id="id_number"type="text" name="name_number" />
    Text<input id="id_text" type="text" name="name_text" />
    <input type="submit"/>
</form>

In the controller I have this code:

  [HttpPost]
        public ActionResult ViewPost(int? name_number, string name_text)
        {
            return View();
        }

Also in the controller I have a GET method for the NewView, which will check the values and concat them, and show the resultant String in a ViewBag.Message:

        public ActionResult NewView(int? number, String name)
        {
           String urlParam = "";
            if (number.HasValue)
            {
                urlParam += " Value number=" + number;
            }
            if (name != null)
            {
                urlParam += " Value name=" + name;
            }
            if (urlParam == "")
            {
                urlParam = "No values";
            }
            ViewBag.Message = urlParam;

            return View();
        }

when I press the submit button, I get Resource not found. Requested URL: /Home/NewView but when going by writing the URL I can go with no problems

Your form is sending a POST request:

method="POST"

But you claim to be expecting a GET request:

in the controller I have a GET method for the NewView

Either change the form to a GET request:

method="GET"

or change the controller action to accept a POST:

[HttpPost]
public ActionResult NewView(int? number, String name)
{
    //...
}

Additionally, the form element names must be the same as the variables you want them to populate. So either change them in the form:

name="number"
...
name="name"

or change them in the action method:

public ActionResult NewView(int? name_number, String name_text)

A note on terminology which may clear some of this up for you...

which I want that when pressed the input button, will send the info from the form to another view

This is incorrect. You don't send values to a view, you send them to a controller action. Anything that goes to the server is generally going to a controller action. That action method can do whatever it needs to do with those values, including returning a view.

But the overall interaction is that the in-browser code (a link, a form, JavaScript and AJAX, etc.) makes requests to server-side actions and those actions return a variety of responses.
