While writing methods in controllers you need to know which method is of Get type and which is of Post type

In my example i have write code for simple user registeration so there are two views for it one Get and one Post

 public class RegisterController:Controller
    {
        EmployeeRepository EmpRepObj = null;
        public ActionResult Home()
        {
            return View();
        }
    
        [HttpGet]
        public ActionResult RegisterEmployee()
        {
            return View();
        }

        [HttpPost]
        public ActionResult RegisterEmployeeDetails(EmployeeModel EmpModel)
        {
            try
            {
                EmpRepObj = new EmployeeRepository();

                EmpRepObj.SaveDetails(EmpModel);
            }
            catch (Exception ex)
            {

            }
            return View(EmpModel);
        }
    }

First is of Get type because it is used to input values from user

Second is of Post type because it is used to submit details into the database

First view looks like this:

model MVC_Demo.Models.EmployeeModel

@{
    ViewBag.Title = "RegisterEmployee";
}
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script> 
<h2>RegisterEmployee</h2>

@using (Html.BeginForm("RegisterEmployeeDetails", "Register", new { ReturnUrl = ViewBag.ReturnUrl }, FormMethod.Post, new { @class = "form-horizontal", role = "form" })) 
{
    @Html.AntiForgeryToken()
    
    <div class="form-horizontal">
        <h4>EmployeeModel</h4>
        <hr />
        @Html.ValidationSummary(true, "", new { @class = "text-danger" })
        <div class="form-group">
            @Html.LabelFor(model => model.FirstName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.FirstName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.FirstName, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.MiddleName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.MiddleName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.MiddleName, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.LastName, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.LastName, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.LastName, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.PhoneNo, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.PhoneNo, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.PhoneNo, "", new { @class = "text-danger" })
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.Address, htmlAttributes: new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Address, new { htmlAttributes = new { @class = "form-control" } })
                @Html.ValidationMessageFor(model => model.Address, "", new { @class = "text-danger" })
            </div>
        </div>

  

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="Create" class="btn btn-default" />
            </div>
        </div>
    </div>
}

<div>
    @Html.ActionLink("Back to List", "Index")
</div>

Second view looks like this:

@model MVC_Demo.Models.EmployeeModel

@{
    ViewBag.Title = "RegisterEmployeeDetails";
}

<h2>RegisterEmployeeDetails</h2>

<div>
    <h4>EmployeeModel</h4>
    <hr />
    <dl class="dl-horizontal">
        <dt>
            @Html.DisplayNameFor(model => model.FirstName)
        </dt>

        <dd>
            @Html.DisplayFor(model => model.FirstName)
        </dd>

        <dt>
            @Html.DisplayNameFor(model => model.MiddleName)

<p>
    @Html.ActionLink("Edit", "Edit", new { /* id = Model.PrimaryKey */ }) |
    @Html.ActionLink("Back to List", "Index")
