[英]Why is WindowsPrincipal.IsInRole always returning false for the “Administrators” group?
My local user account is in the Administrators group, and I wanted to simply figure out how a windows forms project would determine if I'm in the administrators group. 我的本地用户帐户位于Administrators组中,我想简单地弄清楚Windows窗体项目将如何确定我是否在管理员组中。 So, I started a windows forms project and tried the following: 所以,我启动了一个Windows窗体项目,并尝试了以下内容:
[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());
}
Why are all the above checks failing? 为什么上述所有检查都失败了?
try 尝试
currentUser1.IsInRole(WindowsBuiltInRole.Administrator)
"In Windows Vista and later versions of the Windows operating system, User Account Control (UAC) determines the privileges of a user. [..] The code that executes the IsInRole method does not display the Consent dialog box. The code returns false if you are in the standard user role, even if you are in the Built-in Administrators group" “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方法的代码不显示”同意“对话框。如果代码返回false,则代码返回false即使您在内置管理员组中,您也处于标准用户角色中
