推荐答案

试试这个

try this

Response.WriteFile(Server.MapPath(file));

希望这有助于

hope this helps

您好，



您可以使用ASHX文件（例如，downloadfile.ashx）并使用以下代码（未经过测试，但它会是这样的）其中：

Hello,

You can use ASHX file (say, downloadfile.ashx) and use the following code (not tested, but it will be something like that) in it:

Response.Clear();
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=abc.txt");
Response.WriteFile(Server.MapPath("\\servername\folder1\folder2\folder3\abc.txt"));
Response.End();

然后在你的锚标签中使用它：

and then use this in your anchor tag like:

<a href="downloadfile.ashx"  target=""_blank"">Click me</a>

注意：您还可以传递参数以下载不同的文件，例如：

Note: You can also pass parameters for downloading different files like:

<a href="downloadfile.ashx?file=abc.txt"  target=""_blank"">Click me</a>

然后，在ashx文件中，使用文件名下载相应的文件。



然后，替换以下代码

and then, in ashx file, use the file name to download the appropriate file.

Then, replace your following code

Response.Write("<br>" + file);

通过这样的东西

by something like this

Response.Write("<br><a href="downloadfile.ashx?file=" + file + "">" + file + "</a>");</pre>

你可能也许需要从绝对更改您的文件路径亲戚。



希望它有所帮助;）

You'll maybe need to change your filepath from absolute to relative.

Hope it helps ;)
