ASP MVC5 - 身份。如何获得当前ApplicationUser [英] ASP MVC5 - Identity. How to get current ApplicationUser

问题描述

我文章的实体在我的项目具有 ApplicationUser 命名属性作者。我怎样才能获得当前登录的完整的对象 ApplicationUser 。在创建新的文章中，我必须设置作者属性文章来电流 ApplicationUser 。

在老会员mechanizm这很简单，但在新的Identity mechanizm我不知道如何做到这一点。

我试图做到这一点的方式：

• 添加using语句身份扩展名：使用Microsoft.AspNet.Identity;


• 然后我试图让当前用户： ApplicationUser的currentUser = db.Users.FirstOrDefault（X =＆GT; x.Id == User.Identity.GetUserId（））;

但我得到异常：

  

LINQ到实体无​​法识别方法'System.String GetUserId（System.Security.Principal.IIdentity）的方法，而这种方法不能被翻译成店前pression。
    来源=的EntityFramework

解决方案

我的错，我不应该使用LINQ查询里面的方法; P

正确code：

 字符串currentUserId = User.Identity.GetUserId（）;
ApplicationUser的currentUser = db.Users.FirstOrDefault（X =＆GT; x.Id == currentUserId）;
 

I have Article entity in my project which have ApplicationUser property named Author. How can I get full object of current logged ApplicationUser. While creating new article I have to set Author property in Article to current ApplicationUser.

In old Membership mechanizm it was simple but in new Identity mechanizm I don't know how to do this.

I tried to do this that way:

• Add using statement for Identity extensions: using Microsoft.AspNet.Identity;
• Then I try to get current user: ApplicationUser currentUser = db.Users.FirstOrDefault(x => x.Id == User.Identity.GetUserId());

But I get exception :

LINQ to Entities does not recognize the method 'System.String GetUserId(System.Security.Principal.IIdentity)' method, and this method cannot be translated into a store expression. Source=EntityFramework

解决方案

My mistake, I shouldn't to use method inside LINQ query ;p

Correct code:

string currentUserId = User.Identity.GetUserId();
ApplicationUser currentUser = db.Users.FirstOrDefault(x => x.Id == currentUserId);
