Get Username from Email address using C# in ASP.Net MVC

Hi florenz,

I have created sample code which full-fill your requirement.

HomeController

public class HomeController : Controller
{
    public ActionResult Index()
    {
        return View();
    }

    public ActionResult GetUserName(Users user)
    {
        string UserName = (user.EmailId).Split('@')[0]; // you are get here username.
        return View();
    }
}

View

<div>
    <%using (Html.BeginForm("GetUserName", "Home", FormMethod.Post))
        { %>
    <table border="0" cellpadding="0" cellspacing="0">
        <tr>
            <td>
                UserName:
                <input type="text" name="EmailId" />
            </td>
            <td>
            </td>
            <td>
                <input type="submit" name="Get UserName" value="Submit" />
            </td>
        </tr>
    </table>
    <%} %>
</div>

Model

public class User
{
    public string EmailId { get; set; }
}
