ASP. NET Method for obtaining Form form value in MVC controller

This paper gives an example of how ASP. NET obtains the value of Form form in MVC controller. Share it for your reference, as follows:

In the MVC controller, if we want to get the value of a tag element in the form directly, we can use the FormCollection class provided in MVC, and the specific usage is as follows:

View section:

@using (Html.BeginForm())
{
  <text> The value you entered is: </text><span>@ViewBag.FormValue</span>
  <input type="text" name="txtName" id="txtName" value="" />
  <input type="submit" name="btnSave" id="btnSave" value=" Mention   Hand in " />
}

Controller section:

[HttpPost]
public ActionResult Index(FormCollection formCol)
{
  ViewBag.FormValue = formCol["txtName"];
  return View();
}
