Auto creating folders when using System.IO.File.Move
提问by roryok
I'm updating an old winforms app which moves files to new locations using regex and System.IO.File.Move
我正在更新一个旧的 winforms 应用程序，它使用正则表达式和 System.IO.File.Move 将文件移动到新位置
Under windows 7, the old app worked fine. If a folder didn't exist, File.Move would create it
在 Windows 7 下，旧的应用程序运行良好。如果文件夹不存在，File.Move 会创建它
System.IO.File.Move("c:\stuff\a.txt","c:\stuff\a\file.txt");
System.IO.File.Move("c:\stuff\b.txt","c:\stuff\b\file.txt");
System.IO.File.Move("c:\stuff\c.txt","c:\stuff\c\file.txt");
However, under Windows 8 it seems that I have to manually create each folder in the path first. I get an error if I try and move to a folder that doesn't exist yet. Anyone know a way around this? I'd rather not have to create each folder
但是，在 Windows 8 下，我似乎必须先在路径中手动创建每个文件夹。如果我尝试移动到尚不存在的文件夹，则会收到错误消息。任何人都知道解决这个问题的方法吗？我宁愿不必创建每个文件夹
NOTE: The new, updated app is on WPF rather than winforms. Not sure if that's relevant
注意：新的、更新的应用程序在 WPF 上而不是在 winforms 上。不确定这是否相关

Before you File.Move()you could do:
在File.Move()你可以做之前：
new System.IO.FileInfo("c:\stuff\a\file.txt").Directory.Create();
The above will create the "stuff" and "a" folders if they don't exist.
如果它们不存在，上面将创建“stuff”和“a”文件夹。
