感谢你所有的答案。我是从收到的答案为止主要是在提到两点感兴趣的：

Thank you for all the answers. From the answers received so far I am interested mostly in two points mentioned:

1. <一个href="http://stackoverflow.com/questions/528858/what-is-the-appdata-folder-used-for-in-visual-studio/528876#528876">App_Data本质上是基于文件的数据存储
存储点
2. <一个href="http://stackoverflow.com/questions/528858/what-is-the-appdata-folder-used-for-in-visual-studio/528872#528872">It不应该是可见的网站，是一个地方的Web应用程序存储和读取
数据

1. App_Data is essentially a storage point for file-based data store
2. It should not be viewable by the web and is a place for the web app to store and read data from

会有人能够指定的不会被Web可视保证？ 我可以依靠这一事实执行标准部署的时候，或者我需要检查服务器上的某些IIS设置以及。

Would someone be able specify how the "not viewable by the web" is ensured? Can I rely on that fact when performing standard deployment, or do I need to check some IIS settings on the server as well.

在这种情况时，我有一组我想只有从应用程序可以访问的PDF文件。请问App_Data文件夹是正确的地方使用，或者我应该创建一个单独的文件夹，并手动设置IIS以确保它不被Web访问？

In the situation when I have a set of pdf files that I want to be accessible only from the application. Would App_Data folder be the right place to use, or should I create a separate folder and manually set IIS to ensure that it is not accessible by Web?

推荐答案

的App_Data基本上是基于文件的数据存储的存储点（而不是一个SQL Server数据库存储为例）。一些简单的网站使用它的内容为XML，例如存储，通常其中对于DB托管费用是昂贵的。

App_Data is essentially a storage point for file-based data stores (as opposed to a SQL server database store for example). Some simple sites make use of it for content stored as XML for example, typically where hosting charges for a DB are expensive.
