GetUserName（）havig错误

谢谢！

解决方案

从 RyanDev 评论



使用 HttpContext.Current.User.Identity.Name 获取 UserName 并启用 Windows身份验证 [ ^ ]

< blockquote>不确定你是否已经弄明白了，但是要使用'GetUserName'方法，你可能需要在前端页面上包含Microsoft.AspNet.Identity的命名空间。



VB.NET：

<％@ Import Namespace =Microsoft.AspNet.Identity％> 

CS1061: 'System.Security.Principal.IIdentity' does not contain a definition for 'GetUserName' and no extension method 'GetUserName' accepting a first argument of type 'System.Security.Principal.IIdentity' could be found (are you missing a using directive or an assembly reference?)

What I have tried:

getting this error in Site.master designer file..

• <a runat="server" href="~/Account/Manage" title="Manage your account">Hello, <%: Context.User.Identity.GetUserName() %> !

GetUserName() havig error
Microsoft.AspNet.Identity alredy added

thank you!

Posting as Solution From RyanDev Comments

use HttpContext.Current.User.Identity.Name to get the UserName and Enable the Windows Authentication [^]

not sure whether you already figure this out, but to use 'GetUserName' method, you may need to include namespace of "Microsoft.AspNet.Identity" on your front-end page.

VB.NET:

<%@ Import Namespace="Microsoft.AspNet.Identity" %>
