I need to test if the application (written in C#, running os Windows XP/Vista/7) is running as administrator (as in right-click .exe -> Run as Administrator, or Run as Administrator in the Compability tab under Properties).
我需要测试应用程序（用 C# 编写，运行 os Windows XP/Vista/7）是否以管理员身份运行（如右键单击 .exe -> 以管理员身份运行，或在“属性”下的“兼容性”选项卡中以管理员身份运行） .
I have googled and searched StackOverflow but i can not find a working solution.
我用谷歌搜索并搜索了 StackOverflow，但我找不到可行的解决方案。
My last attempt was this:
我最后一次尝试是这样的：
if ((new WindowsPrincipal(WindowsIdentity.GetCurrent()))
.IsInRole(WindowsBuiltInRole.Administrator))
{
...
}

Try this
尝试这个
public static bool IsAdministrator()
{
var identity = WindowsIdentity.GetCurrent();
var principal = new WindowsPrincipal(identity);
return principal.IsInRole(WindowsBuiltInRole.Administrator);
}
This looks functionally the same as your code, but the above is working for me...
这在功能上看起来与您的代码相同，但上述内容对我有用...
doing it functionally, (without unnecessary temp variables) ...
在功能上做到这一点，（没有不必要的临时变量）......
public static bool IsAdministrator()
{
return (new WindowsPrincipal(WindowsIdentity.GetCurrent()))
.IsInRole(WindowsBuiltInRole.Administrator);
}
or, using expression-bodied property:
或者，使用表达式主体属性：
public static bool IsAdministrator =>
new WindowsPrincipal(WindowsIdentity.GetCurrent())
.IsInRole(WindowsBuiltInRole.Administrator);
