如何使用数据库中的filepath从服务器下载文件？ [英] How do I download a file from server using filepath from database?

问题描述

我有这个应用程序（Winform），我需要使用保存在数据库中的文件路径下载文件。我试过谷歌搜索，但我真的不知道从哪里开始。



示例：

---------- --------------------

ID：1

文件路径：host / test.txt

------------------------------

[BUTTON]







单击按钮时，我想使用文件（从文件服务器）将文件下载到特定文件夹客户端PC？



我真的非常需要它。有链接吗？或者教程？

感谢提前！ ：）

解决方案

正如您所提到的文件服务器，很可能是指Windows文件共享服务，它可以与任何其他文件系统使用完全相同的名称，所以您可以像复制任何其他文件一样复制/移动/重命名/删除文件，具体取决于权限等。对于文件命名，您需要使用UNC名称：

如果要从ftp s下载文件请关注此链接：如何：使用FTP下载文件 [ ^ ]



您可以像这样访问服务器上的文件：

\\servername \directory\subdirectory\\\
ameoffile

或通过映射：

Z：\ nameoffile

其中

Z：等于 \\servername \directory\subdirectory \

I have this application (Winform) where in I need to download a file using the file path saved on the database . I tried googling but I really don't know where to start.

Example:
------------------------------
ID:1
Filepath: host/test.txt
------------------------------
[BUTTON]



When I click the button, I want to download the file (from a file server) to a specific folder using a client PC?

I really need it badly. Any links? or tutorials?
THANKS IN ADVANCE! :)

解决方案

As you mentioned a file server, most likely you mean Windows file sharing service, which can be used in exact same name as any other file system, so you can copy/move/rename/delete files in the same way as any other file, depending on permissions, etc. For file naming, you need to use UNC names:

If you want to download file from ftp server, please follow this link: How to: Download Files with FTP[^]

You can access to the file on server like this:
\\servername\directory\subdirectory\nameoffile
or via mapping:
Z:\nameoffile
where
Z: is equal to \\servername\directory\subdirectory\
