Question

我需要知道我的windows currentuser是域用户还是本地用户？我得到了我的CurrentPrincipal：

 System.Threading.Thread.CurrentPrincipal = new WindowsPrincipal(WindowsIdentity.GetCurrent());

Answer 1

通常，Windows NON域用户没有UPN名称。如下所示如果我用/ upn发射WHOAMI：

C:\>WHOAMI /UPN
ERROR: Unable to get User Principal Name (UPN) as the current logged-on user
       is not a domain user.

基于此使用以下代码，我们可以找到用户是否是域用户。

 var upnName = System.DirectoryServices.AccountManagement.UserPrincipal.Current.UserPrincipalName;
    if (upnName == null)
    {
        //not a domain user
    }

另一种冗长的方法是以SAM格式获取用户名。然后使用DirectoryEntry，DirectorySearcher和其他AD API迭代机器的所有连接域，并查找用户是否在我们迭代的任何域中。

查找计算机的所有域ex1和ex2

Answer 2

我没有AD，但我希望这可能有用：

public bool IsDomainUser()
{
  bool isDomain = false; 
  foreach (var grp in WindowsIdentity.GetCurrent().Groups)
  {
      if (grp.IsValidTargetType(typeof(SecurityIdentifier)))
      {
        SecurityIdentifier si = 
                (SecurityIdentifier)grp.Translate(typeof(SecurityIdentifier));
        // not sure if this is right, but I'm not in a domain and don't have this SID
        // I do have LocalSID however, so you might need to turn it around,
        // if you have LocalSid you are not using a domain acount
        if (si.IsWellKnown(WellKnownSidType.BuiltinDomainSid))
        {
            isDomain = true;
        }
      }
   }
   return isDomain;
 }



   // for debugging list SIDS for current user and its groups
   foreach (var obj in Enum.GetValues(typeof(WellKnownSidType)))
   {

    if (WindowsIdentity.GetCurrent().User.IsWellKnown((WellKnownSidType)obj))
    {
        Debug.WriteLine("User:" + obj.ToString());

    }

    foreach (var grp in WindowsIdentity.GetCurrent().Groups)
    {
        if (grp.IsValidTargetType(typeof(SecurityIdentifier)))
        {
            SecurityIdentifier si = 
                 (SecurityIdentifier) grp.Translate(typeof(SecurityIdentifier));
            if (si.IsWellKnown((WellKnownSidType)obj))
            {
                Debug.WriteLine("Grp: " + grp.ToString() + " : " + obj.ToString());
            }
        }
    }
  }

Answer 3

using System.DirectoryServices.AccountManagement;

bool IsDomainUser()
{
    return UserPrincipal.Current.ContextType == ContextType.Domain;
}
