为什么 WindowsPrincipal.IsInRole 总是为“管理员”组返回 false?

题
我的本地用户帐户位于管理员组中,我想简单地弄清楚 Windows 窗体项目如何确定我是否位于管理员组中。因此,我启动了一个 Windows 窗体项目并尝试了以下操作:
[STAThread]
static void Main()
{
string adminGroup1 = @"BUILTIN\Administrators";
string adminGroup2 = Environment.MachineName + @"\Administrators";
string adminGroup3 = Environment.MachineName.ToLower() + @"\Administrators";
string adminGroup4 = "Administrators";
string adminGroup5 = "administrators";
AppDomain.CurrentDomain.SetPrincipalPolicy(PrincipalPolicy.WindowsPrincipal);
WindowsPrincipal currentUser1 = (WindowsPrincipal)Thread.CurrentPrincipal;
bool IsAdmin1_1 = currentUser1.IsInRole(adminGroup1); // false
bool IsAdmin1_2 = currentUser1.IsInRole(adminGroup2); // false
bool IsAdmin1_3 = currentUser1.IsInRole(adminGroup3); // false
bool IsAdmin1_4 = currentUser1.IsInRole(adminGroup4); // false
bool IsAdmin1_5 = currentUser1.IsInRole(adminGroup5); // false
WindowsPrincipal currentUser2 = new WindowsPrincipal(WindowsIdentity.GetCurrent());
bool IsAdmin2_1 = currentUser2.IsInRole(adminGroup1); // false
bool IsAdmin2_2 = currentUser2.IsInRole(adminGroup2); // false
bool IsAdmin2_3 = currentUser2.IsInRole(adminGroup3); // false
bool IsAdmin2_4 = currentUser1.IsInRole(adminGroup4); // false
bool IsAdmin2_5 = currentUser2.IsInRole(adminGroup5); // false
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
为什么上述所有检查都失败了?
解决方案
尝试
currentUser1.IsInRole(WindowsBuiltInRole.Administrator)
看 微软软件定义网络.
“在 Windows Vista 和更高版本的 Windows 操作系统中,用户帐户控制 (UAC) 确定用户的权限。[..] 执行 IsInRole 方法的代码不会显示“同意”对话框。如果您处于标准用户角色,即使您位于内置管理员组,代码也会返回 false”
