从ASP.NET页面获取Windows登录

Question

Just like the title states. Need the windows logon and domain info from within our asp.net page.

I tried

string userName = System.Security.Principal.WindowsIdentity.GetCurrent().Name; 

but it returns the IIS App Pool not the user name

Thanks

Answer 1

Try HttpContext.User , accessible simply as User from the code behind. It returns both the domain and username, but should be easy enough to trim for your needs. It's worked for me in the past. You can also use this to manage roles in your application, if you need to.

EDIT
Below are the relevant portions of my web.config. I also used aspnet_regsql.exe to setup the tables needed for the role manager in my database. I could then use User.Identity.Name and User.Identity.IsInRole

<connectionStrings>
    <clear/>
    <add name="SqlRoleManagerConnection"
         connectionString="myConnectionString">
    </add>
  </connectionStrings>

  <system.web>
    <authentication mode="Windows" />
    <authorization>
      <deny users="?"/>
    </authorization>
    <roleManager enabled="true" defaultProvider="SqlRoleManager">
      <providers>
        <clear/>
        <add name="SqlRoleManager"
             type="System.Web.Security.SqlRoleProvider"
             connectionStringName="SqlRoleManagerConnection"
             applicationName="myAppName" />
      </providers>
    </roleManager>
  </system.web>

Answer 2

This is my code in VB.net

var strUser = System.Web.HttpContext.Current.User.Identity.Name

so C# must be in the lines of: (not tested) string strUser = System.Web.HttpContext.Current.User.Identity.Name;

In the Web.Config file

<configuration>
    <system.web>
        <authentication mode="Windows"/>
        <identity impersonate="true" />
    </system.web>
</configuration>
