Question

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。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());
}

为什么上述所有检查都失败了？

试

currentUser1.IsInRole(WindowsBuiltInRole.Administrator)

请参阅MSDN。

“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。如果您处于标准用户角色，则返回false，即使您位于内置管理员组“

中也是如此

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