要将我的临时文件写入哪里? [英] Where to write my temporary files to?

问题描述

我有很多byte []代表pdf.每个字节数组都需要在应用程序的开头加载，并在我的GUI上显示为缩略图.到目前为止，我已经设法使用以下命令将文件写入临时位置:

I have numerous byte[] representing pdf's. Each byte array needs to be loaded at the start of the application and shown as a thumbnail on my gui. So far I have managed to write the files to a temp location using:

System.IO.Path.GetTempPath();

然后使用此路径获取所有pdf文件，使用

Then using this path I get all pdf files, write them using

System.IO.File.WriteAllBytes(fileName, arrayOfPdfs[i]);

，然后导航到该目录，获取所有pdf文件，并将它们转换为我的应用程序中的缩略图.

and then navigate to that directory, get all pdf files and turn them in to thumbnails in my app.

问题是我只希望将刚刚放置在临时位置的pdf文件保存起来，所以我还能如何存储这些pdf文件，甚至还能将它们存储在其他位置，所以我知道何时将它们转为缩略图，我正在读取的文件是我刚刚写的文件?这样可以确保用户只查看与他们在我的系统上搜索相关的pdf.

The thing is I only want the pdfs I have just put in the temp location only, so how else can I store the pdfs, or even where else can I store them so I know when I come to turn them in to thumbnails, the files I am reading are the ones I have just written? This is so I can be sure the user is only looking at the relevant pdfs that relate to their search on my system.

谢谢.

推荐答案

我会在您的用户中推荐

I would recommend in your users ApplicationData/LocalApplicationData folder provided by the OS for your app..

Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData);

当然，如果存储不需要保持很长时间(实际上是临时的)，那么您可以使用temp文件夹并在其中创建一个文件夹来隔离文件.

Of course if the storage doesn't need to persist very long (really temporary) then you could just use the temp folder and create a folder inside of it to isolate your files.
