c# - 为什么目录上的 File.Delete() 会产生 UnauthorizedAccessException？

Question

如果我调用System.IO.File.Delete()并传递一个目录名，我会得到一个目录名，UnauthorizedAccessException尽管问题与任何类型的权限无关，我想InvalidOperationException在这里会更合适。

为什么会抛出这个特定的异常？这是设计错误还是有任何原因？

Answer 1

No idea, but it smells like a design fault because the Directory.Delete has a different behavior that File.Delete. Directory.Delete will throw a DirectoryNotFoundException if the path actually refers to a file instead of directory. One would expect that the same kind of exception would be thrown in these two cases.
