将Uploated文件链接到Form记录 [英] Link Uploated files to Form record

推荐答案

不确定我是否正确理解了您的问题。所以我做了一些假设。



- 我假设你想把一个文件分配给一个记录（上传与否在这里并不重要）

- 您希望在显示该记录时显示该文件的链接（再次。哪种模式无关紧要）





您所需要的只是将文件名存储在您记录的字段中（您还可以引用另一个表等）。



显示记录只是创建一个超链接，你链接到该文件夹​​（可通过网络访问）和文件..



示例：



用户上传文件testfile.txt，将文件存储到D：\\\\YourApplication\Files\testfile.txt



显示链接时，文件的相对路径可能是〜/ Files / testfile.txt（注意：代字号（〜）代表你的应用程序根目录。

所以你可以直接在录音机上存储〜/ Files / testfile.txt d或只记录文件中的文件名，当你生成< asp：hyperlink> 控件时，你可以设置 NavigateUrl 它在此路径中的属性。

Not sure if I understand your question correctly. So I'm making a few assumptions.

- I assume you want to assign a file to a record (uploaded or not doesn't really matter here)
- You want to show a Link to that file when displaying that records (again. which mode doesn't really matter)


All you need is to store the filename in a field of you record (you can also have a reference to another table etc.).

When showing the record just create a Hyperlink where you link to the folder (accessible over the web) and the file..

Example:

User uploads file "testfile.txt" you store the file to "D:\www\YourApplication\Files\testfile.txt"

When showing the link the relative path to the file could be "~/Files/testfile.txt" (Note: the tilde char (~) is representing your application root.
So you could either store "~/Files/testfile.txt" directly on the record or just the filename itself on the record and when you generate the <asp:hyperlink> control you can set the NavigateUrl Property of it to this path.
