c# - 在登录页面中使用页面用户身份名称

Question

我使用默认模板在 Visual Studio 2012 中创建了一个项目。我希望每个用户都能够登录并被重定向到不同的页面。我已经实现了适用于首次用户登录的代码。但是，如果我注销，然后使用其他用户登录，则该用户不会被重定向。当我调试应用程序时，在第二次登录时，它在用户名上显示为空白。我已将代码放在 page_load 事件中，是否有更好的事件或更好的方法来实现此代码？

var Username = Page.User.Identity.Name;

if (Username == "You" || Username == "you")
{
    Response.Redirect("~/you.aspx");
}
else if (Username == "Me" || Username == "me")
{
    Response.Redirect("~/me.aspx");
}
else if (Username == "Them" || Username == "them")
{
    Response.Redirect("~/Them.aspx");
}

我也试过这段代码，但是没有一个用户在登录后被重定向。在我看来，代码的 aspx 部分没有在或@登录后触发:

代码隐藏:

public partial class Login : Page
{
    protected void Page_Load(object sender, EventArgs e)
    {


    }
    protected void LoggedIn(object sender, EventArgs e)
    {
        //This is redirect the user to their page
        switch (Page.User.Identity.Name.ToLower())
        {
            case "me":
                Response.Redirect("~/me.aspx");
                break;
            case "you":
                Response.Redirect("~/you.aspx");
                break;
            case "them":
                Response.Redirect("~/them.aspx");
                break;
        }
    }
    protected void Unnamed6_Click(object sender, EventArgs e)
    {

    }
}

此处的 Aspx 代码:

<%@ Page Title="Log in" Language="C#" MasterPageFile="~/Site.Master" AutoEventWireup="true" CodeBehind="Login.aspx.cs" Inherits="ChoresLists.Account.Login" %>
<%@ Register Src="~/Account/OpenAuthProviders.ascx" TagPrefix="uc" TagName="OpenAuthProviders" %>

                            <asp:Label runat="server" AssociatedControlID="RememberMe" CssClass="checkbox">Remember me?</asp:Label>
                        </li>
                    </ol>
                    <asp:Button runat="server" CommandName="Login" Text="Log in" OnClick="Unnamed6_Click" />
                </fieldset>
            </LayoutTemplate>

        <p>
            <%--<asp:HyperLink runat="server" ID="RegisterHyperLink" ViewStateMode="Disabled">Register</asp:HyperLink>
            if you don't have an account.--%>
        </p>

    <section id="socialLoginForm">

嘿嘿嘿你为什么使用:

if (Username == "You" || Username == "you")
{
    Response.Redirect("~/you.aspx");
}
if (Username == "Me" || Username == "me")
{
    Response.Redirect("~/me.aspx");
}
if (Username == "Them" || Username == "them")
{
    Response.Redirect("~/Them.aspx");
}

而不是使用:

if (Username == "You" || Username == "you")
{
   Response.Redirect("~/you.aspx");
}
else if (Username == "Me" || Username == "me")
{
   Response.Redirect("~/me.aspx");
}
else if (Username == "Them" || Username == "them")
{
   Response.Redirect("~/Them.aspx");
}
