asp.net-mvc – 使用SimpleMembership获取用户信息

_Layout.cshtml查看

@{Html.RenderAction("UserInfo","Account");}

查看模型

public class UserInfo
{
    public bool IsAuthenticated {get;set;}
    public string ForeName {get;set;}
}

账户管理员

public PartialViewResult UserInfo()
{
   var model = new UserInfo();

   model.IsAutenticated = httpContext.User.Identity.IsAuthenticated;

   if(model.IsAuthenticated)
   {
       // Hit the database and retrieve the Forename
       model.ForeName = Database.Users.Single(u => u.UserName == httpContext.User.Identity.UserName).ForeName;

       //Return populated ViewModel
       return this.PartialView(model);
   }

   //return the model with IsAuthenticated only
   return this.PartialView(model);
}

UserInfo视图

@model UserInfo

@if(Model.IsAuthenticated)
{
    <text>Hello,<strong>@Model.ForeName</strong>!
    [ @Html.ActionLink("Log Off","LogOff","Account") ]
    </text>
}
else
{
    @:[ @Html.ActionLink("Log On","LogOn","Account") ]
}

这做了一些事情并带来了一些选择：

>保持您的视图不必嗅探HttpContext.让控制器处理它.
>您现在可以将其与[OutputCache]属性结合使用,这样您就不必在每个页面中呈现它.>如果您需要向UserInfo屏幕添加更多内容,则只需更新ViewModel并填充数据即可.没有魔法,没有ViewBag等.
