问题摘要：
我有一个控制台应用程序，在将许多文件夹和文件复制到新位置（本地驱动器）之后，它会删除某些文件/文件夹。它删除的这些文件类型之一是.exe文件。当试图删除所述文件时，它会给我一个拒绝访问错误。（这也会在尝试删除其他类型的文件和文件夹时发生）
其他说明：
我看到了几个问题，例如Unable to delete .exe file through c#.但是，该过程从未在我的本地计算机上运行，也没有在从它复制的源上运行。我既是本地管理员又是域名管理员，我对我正在使用的目录中的所有文件夹和文件拥有所有权。但是在尝试从代码中删除文件时，它仍然拒绝我访问。但我可以手动删除这些文件/文件夹。（点击删除键）
问题：
如上所述，我正在寻找一种方法来解决此问题，拒绝我删除这些“非法”文件类型并将其从我的代码中删除。
我的代码:(已更新）

非常感谢任何帮助。如果这个问题已在其他地方直接回答，请随时在评论中提及。如上所述，我一直在查看有关此问题的过去问题，但尚未找到解决方案。不然谢谢你的帮助。
答案 0 :(得分：1)
弄清楚问题是文件被标记为“只读”所以我在删除文件之前添加了一个if语句来检查它是否是，如果需要则删除标记。这是成功删除所有想要的文件的代码。
