File.Move以外的更快文件移动方法 [英] Faster file move method other than File.Move

问题描述

我有一个控制台应用程序，大约需要625天才能完成。除非有办法使它更快。

I have a console application that is going to take about 625 days to complete. Unless there is a way to make it faster.

首先，我正在一个包含大约4,000,000个文件的目录中工作。我正在一个数据库中工作，每个文件中都有一行，然后每个文件中都有一行。

First off I am working in a directory that has around 4,000,000 files in if not more. I'm working in a database that has a row for each file and then some.

现在使用SQL的速度相对较快，瓶颈在于使用 File.Move（）每一步需要18秒才能完成。

Now working with the SQL is relatively fast, the bottleneck is when I use File.Move() each move takes 18 seconds to complete.

有没有比 File.Move（）？

这是瓶颈：

File.Move(Path.Combine(location, fileName), Path.Combine(rootDir, fileYear, fileMonth, fileName));

所有其他代码的运行速度都非常快。我需要做的就是将一个文件移到新位置，然后更新数据库位置字段。

All of the other code runs pretty fast. All I need to do is move one file to a new location and then update the database location field.

如果需要，我可以显示其他代码，但实际上，上面是

I can show other code if needed, but really the above is the only current bottleneck.

推荐答案

事实证明，从File.Move切换到设置FileInfo并使用.MoveTo可以显着提高速度。

It turns out switching from File.Move to setting up a FileInfo and using .MoveTo increased the speed significantly.

现在运行大约35天，而不是625天。

It will run in about 35 days now as opposed to 625 days.

FileInfo fileinfo = new FileInfo(Path.Combine(location, fileName));
fileinfo.MoveTo(Path.Combine(rootDir, fileYear, fileMonth, fileName));
