C# 判断程序是否已管理员身份运行

代码：

public static Boolean IsAdministrator() {
      System.Security.Principal.WindowsIdentity identity = System.Security.Principal.WindowsIdentity.GetCurrent();
      System.Security.Principal.WindowsPrincipal principal = new System.Security.Principal.WindowsPrincipal(identity);
      return principal.IsInRole(System.Security.Principal.WindowsBuiltInRole.Administrator);
}
