我已经尝试过了，但是当我运行网页时却找不到该文件.

Hi guys,

i have tried this, but when i run the web page it foes not find the file.

Dim buffer As [Byte]() = client.DownloadData("c:\temp.pdf")
Response.ClearContent()
Response.ContentType = "application/pdf"
Response.AddHeader("content-length", buffer.Length.ToString())
Response.BinaryWrite(buffer)
Response.Flush()
Response.End()

推荐答案

当您说本地计算机"时，我假设您的意思是客户端".
如果是这种情况，您可以尝试在iframe src中使用"file:///C:/temp.pdf".这是否有效取决于浏览器/插件/设置，因为file:///前缀往往会向某些人发出安全警告.

您可以在此处快速阅读: http://en.wikipedia.org/wiki/File_URI_scheme [ ^ ]

如果这对您没有帮助，则最好生成pdf服务器端，然后使用正常的http(s)网址将其显示在iframe中.

希望这会有所帮助.

When you say ''local machine'' I assume you mean the ''client side''.
If this is the case you can try using "file:///C:/temp.pdf" in the iframe src. It will depend on the browser/plugin/settings if this will work or not, since the file:/// prefix tends to throw security warnings for some people.

You can quickly read up on it here: http://en.wikipedia.org/wiki/File_URI_scheme[^]

If this does not help in your situation, it might be best to generate the pdf server side and then show it in the iframe using a normal http(s) url.

Hope this helps.
