If you need to push a value from client side (JavaScript) to server side (your C# code is executed on the server) you need to send it to the server in some fashion.

$(document).ready(function () {
    var UserName = $(".dir span").text();
    UserName.trim().replace("\n", "");

    $.post("@Url.Action("SaveUserName")", { username: UserName });
});

This will post the entered username to the Action SaveUserName on the same controller that your current view was activated from. So on your controller you will need the following Action

public ActionResult SaveUserName(string username)
{
    // This is where you would save the username on the serverside
}

I think you mean '@Url.Action("SaveUsername")'.

Indeed, that is what I meant. Thank you
