：bootstrap adminlte教程2：布局之前台模板
首先用了adminlte来做后台，为了难得麻烦，前台也用了，只是引用JS要少一些。
1.效果展示。
先上PC大屏的效果图。（这是很大众的）
缩小后:
在上头像点击下拉效果。
二.下面是实现步骤。
1.思路：首先user/login进行登录，然后这个login使用了无_loyout布局。登录后转到home/index,所以我在这个控制器中将所有登录用户的信息全Session进系统。
打开HomeController.cs,改写了其中的index方法。
[Authorize]
public ActionResult Index()
{
Session["role"] = ""; //初设一个角色session
string id = User.Identity.GetUserId(); //获取当前用户的ID
if (string.IsNullOrWhiteSpace(id))
{
return new HttpStatusCodeResult(System.Net.HttpStatusCode.BadRequest);
}
var xxxx = UserManager.GetRoles(id) ; //获取该ID的角色序列
if (xxxx == null)
{
Session["role"] = "无";
}
else
{
var userRoles = xxxx as IList<string>; //对象转为string列
foreach (var role in userRoles)
{
Session["role"] = role; //赋值角色的session
}
}
User user = UserManager.FindById(id); //实例化User类
Session["username"] = user.UserName;
Session["birthDate"] = user.BirthDate;
Session["gender"] = user.Gender;
Session["qq"] = user.QQ;
Session["phone"] = user.PhoneNumber;
Session["headerPic"] = user.HeaderPic; //头像的URL session
Session["userId11"] = id; //当前用户的id
Session["userIP"] = HttpContext.Request.UserHostAddress; //当前电脑的ip
return View(user);
}
页index使用的是默认的_layout布局文件，我们只需修改那个布局文件即可。
2.重新设计_layout布局文件。 这个和我们说的adminlte第一课对应，只引用了start.htm示范中的JS和CSS，但我加入了一个我自己写的CSS,主要是调测了几个地方，不重要。
但在下面这句，实在是深蓝色，我难得麻烦，加上了两个重写。

注意在其，用户头像下拉的修改密码，详细资料，要送一个当前用户的ID作参数。
