C# WinForms模拟域管理员创建目录遇权限拒绝问题排查

我在C# WinForms应用的特定模块中尝试模拟域管理员身份，遇到权限问题：

• 当前用户为DE123450\max-neumann，创建Impersonator实例后，弹窗显示身份已切换为DE12345\Administrator（域管理员/本地管理员），说明身份模拟成功
• 但执行Directory.CreateDirectory(@"C:\Program Files (x86)\TEST")时，抛出错误：System.UnauthorizedAccessException: "拒绝访问路径‘C:\Program Files (x86)\TEST’"
• 直接以管理员身份运行程序时，创建目录操作正常

使用的Impersonator类代码如下：

namespace AtbasNetClientInstaller.Functions
{
    #region Using directives.

    using System;
    using System.Security.Principal;
    using System.Runtime.InteropServices;
    using System.ComponentModel;
