User.Identity.Name - 这集引用这带来到您的项目？ [英] User.Identity.Name - which assembly reference brings that into your project?

问题描述

我无法找出引用装配在 User.Identity.Name 从何而来。我怎么发现的？我需要将它添加到一个类库，而不是默认的MVC应用5我做，这样我可以访问它？

的http://msdn.microsoft.com/en-us/library/system.web.httpcontext.user(v=vs.110).aspx

C＃类库/ AUser.cs

 公共类AUser
{
    公共字符串用户名
    {
        得到
        {
            返回User.Identity.Name //不会注意到用户
        }
    }
}
 

解决方案

似乎是在System.Web命名空间。

修改

根据您的额外code

，你必须包括完全合格的名字 - 如：

  HttpContext.Current.User.Identity.Name
 

当你在室外控制器的（或在另一个类）。请注意，如果这个MVC类以外的任何东西使用没有HttpContext的，它会失败（有一个NullReferenceException）。为了确保我们没有任何这些，我们通常是通过HttpContext的还是我们所需要的部分（用户名，网址等）作为函数的参数。

I can't find out which reference assembly the User.Identity.Name comes from. How do I find that out? I need to add it to a class library rather than the default MVC 5 app I have made so that I can have access to it?

http://msdn.microsoft.com/en-us/library/system.web.httpcontext.user(v=vs.110).aspx

C# Class Library / AUser.cs

public class AUser
{
    public string Username
    {
        get
        {
            return User.Identity.Name // doesn't notice User
        }
    }
}

解决方案

Appears to be in the System.Web namespace.

EDIT

Based on your additional code, you have to include the fully qualified name - such as:

HttpContext.Current.User.Identity.Name

When you are outside of a controller (or in another class). Be aware that if this outside of MVC class is used in anything without an HttpContext, it will fail (with a NullReferenceException). To ensure we don't have any of those, we typically either pass the HttpContext or the portions we need (Username, Url, etc) as function parameters.
