Getting The Current User Name In ASP.NET Application
提问by Kevin
I am running a webpage that needs to be able to read the login id of the current user. Here is the code I am using:
我正在运行一个需要能够读取当前用户的登录 ID 的网页。这是我正在使用的代码：
string id = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
Currently this returns the correct login but when I use it in this method:
目前这将返回正确的登录名，但是当我在此方法中使用它时：
protected Boolean isPageOwner()
{
string id = System.Security.Principal.WindowsIdentity.GetCurrent().Name;
alert("User: " + id);
if (id.Equals(pageOwnerID))
{
return true;
}
if (accessPermission.ContainsKey(id))
{
return true;
}
return false;
}
the method returns false even though the id returned is identical to pageOwnerID. I'm really not sure which part of this I am having a problem with.
即使返回的 id 与 pageOwnerID 相同，该方法也会返回 false。我真的不确定我遇到了问题的哪一部分。
On a side note, my login id is of the form string1/string2 but the code retrieves it as string1 + string2 without the slash.
附带说明一下，我的登录 ID 的格式为 string1/string2，但代码将其检索为 string1 + string2 而不带斜杠。
Any advice is appreciated.
任何建议表示赞赏。

Try using this to retrieve the username....
尝试使用它来检索用户名....
if (System.Web.HttpContext.Current.User.Identity.IsAuthenticated)
{
string username = System.Web.HttpContext.Current.User.Identity.Name;
}
It sounds like windows authentication is not being used - you need to disable anonymous access and enable windows integrated security.
听起来好像没有使用 Windows 身份验证 - 您需要禁用匿名访问并启用 Windows 集成安全性。
Add this to your web.config...
将此添加到您的 web.config ...
<system.web>
<authentication mode="Windows"/>
<authorization>
<deny users="?"/>
</authorization>
</system.web>

If you need the current logged in user's identity from within any layer (or Project in your solution) then use:
如果您需要任何层（或解决方案中的项目）中的当前登录用户身份，请使用：
string userId = Thread.CurrentPrincipal.Identity.GetUserId();
string userId = Thread.CurrentPrincipal.Identity.GetUserId();
