我们可以从系统更改默认下载映像位置吗？ [英] Can we change the default download image location from the system?

问题描述

  我们正在从azure下载图像并保存到"C：\ Users \Test \ AppData \ Local \Packages \ Location.w3ew39acqp9x0 \ LocalState" location，然后根据我们在localstate下创建文件夹的用户ID，然后存储图像，

   we are downloading images from azure and saving to "C:\Users\Test\AppData\Local\Packages\location.w3ew39acqp9x0\LocalState" location,then based on the user id we are creating folder under localstate then storing the images,

可以更改位置以将图像存储到应用程序的安装位置，因为用户能够看到图像，

is its possible to change the location to store images to where the app got installed,because the user able to see the images,

如果用户无法看到图像，可以将图像存储到某个安全文件夹。

its possible to store the images to some secure folder,if the user not able to see the image.

推荐答案

>>是否可以更改位置将图像存储到应用程序安装的位置，因为用户能够看到图像，

不，您无法在运行时写入安装目录。它是只读的：

No, you cannot write to the installation directory at runtime. It is read-only: http://stackoverflow.com/questions/10310510/copy-file-into-install-directory-of-metro-style-app

>> ;如果用户无法看到图像，则可以将图像存储到某个安全文件夹中。

您应该将文件写入Local文件夹，Roaming文件夹或Temp文件夹。每个UWP应用程序都有这三个文件夹，因为它们是隔离的，所以它们非常安全。有关更多信息，请参阅Jerry Nixon的博客文章：

You should write files to the Local folder, the Roaming folder or the Temp folder. Every UWP app has these three folders and they are pretty secure since they are isolated.

如果要将文件保存到硬盘驱动器上的另一个文件夹，则需要明确要求用户使用选择器选择此文件夹：

If you want to save the file to another folder on the hard drive you need explicitly ask the user to select this folder using a picker: https://msdn.microsoft.com/en-us/windows/uwp/files/quickstart-using-file-and-folder-pickers
