更新：我很高兴放弃 C# 要求，只看到任何可以列出所有以管理员或系统身份运行的文件的程序，我的问题是有人见过这样的事情吗？
枚举目录中的文件有多种方法，但都遇到相同的问题：
“指定的路径、文件名或两者都太长。完全限定文件名必须小于 260 个字符，目录名必须小于 248 个字符。”
“访问路径 'C:\Users\All Users\Application Data' 被拒绝”
等等
即使在管理员、单用户机器下运行，似乎也无法在不遇到异常\错误的情况下列出所有文件。
仅仅获取windows下所有文件的列表真的是一项不可能完成的任务吗？有没有人能够使用 C# 或任何其他方法获得他们机器上所有文件的完整列表？
这个来自 MS的链接，标题为“枚举目录和文件”，没有显示如何枚举目录和文件，它只显示了不会抛出的内容的一个子集：DirectoryNotFoundException、UnauthorizedAccessException、PathTooLongException、
更新：这是在 C 上运行并尝试枚举所有文件和错误的示例代码。即使以管理员身份运行它，也有一些文件夹不仅可以访问，而且我什至无法将其所有权更改为管理员！例如：“C:\Windows\CSC”
只需查看“错误 {0}.csv”日志文件，即可了解管理员无法访问的位置。
