WPF 检测管理员权限

      // 检查是否是管理员身份
private static bool CheckAdministrator()
{
WindowsIdentity wi = null;
try
{
wi = WindowsIdentity.GetCurrent();
if (wi == null) throw new Exception("未将对象仅用到对象的实例!");
var wp = new WindowsPrincipal(wi);
var runAsAdmin = wp.IsInRole(WindowsBuiltInRole.Administrator);
if (runAsAdmin) return true;
var processInfo = new ProcessStartInfo(Assembly.GetExecutingAssembly().CodeBase)
{
UseShellExecute = true,
Verb = "runas"
}; Process.Start(processInfo);
return false;
}
catch
{
Console.WriteLine("失败!");
return true;
}
finally
{
if (wi != null)
wi.Dispose();
}
}
