IIS PDF上没有显示Adobe PDF

Question

我在下面的代码处理本地(using source code)完全正常。但是当我在IIS7上发布PDF时，Dim strPath = Server.MapPath("~\Reports\GeneratedReport.pdf") my_rpt.ExportToDisk(ExportFormatType.PortableDocFormat, strPath) Dim file = New System.IO.FileInfo(strPath) Dim Process = New Process() If file.Exists Then Process.StartInfo.UseShellExecute = True Process.StartInfo.FileName = strPath Process.Start() Else 'No Report found End If 不再显示..是否存在IIS问题或？ 。 。我花了很多天才解决这个问题。

<select onchange="location = this.value;">
                <option value="/finished">Finished</option>
                <option value="/break">Break</option>
                <option value="/issue">Issues</option>
                <option value="/downtime">Downtime</option>
</select>

如下图所示，您看到AdobeReader正在运行，但它没有显示在我的屏幕上。

当你说＆＃34;没有显示＆＃34;我假设您希望在客户端而不是服务器上打开PDF。通常您会将文件发送到浏览器。 Process.Start()将启动进程服务器端，因此即使允许AppPool启动进程，它也只会在服务器上打开pdf。 以下是将文件从服务器发送到客户端的方法。

string strPath = Server.MapPath("~/reports/GeneratedReport.pdf");

//read the file from disk and convert to a byte array
byte[] bin = File.ReadAllBytes(strPath);

//clear the buffer stream
Response.ClearHeaders();
Response.Clear();
Response.Buffer = true;

//set the correct contenttype
Response.ContentType = "application/pdf";

//set the correct length of the data being send
Response.AddHeader("content-length", bin.Length.ToString());

//set the filename for the file
Response.AddHeader("content-disposition", "attachment; filename=\"GeneratedReport.pdf\"");

//send the byte array to the browser
Response.OutputStream.Write(bin, 0, bin.Length);

//cleanup
Response.Flush();
HttpContext.Current.ApplicationInstance.CompleteRequest();

VB

Dim strPath As String = Server.MapPath("~/reports/GeneratedReport.pdf")

'read the file from disk and convert to a byte array
Dim bin() As Byte = File.ReadAllBytes(strPath)

'clear the buffer stream
Response.ClearHeaders
Response.Clear
Response.Buffer = true

'set the correct contenttype
Response.ContentType = "application/pdf"

'set the correct length of the data being send
Response.AddHeader("content-length", bin.Length.ToString)

'set the filename for the file
Response.AddHeader("content-disposition", "attachment; filename=""GeneratedReport.pdf"""")", send the byte array to the browser, Response.OutputStream.Write(bin, 0, bin.Length))

'cleanup
Response.Flush
HttpContext.Current.ApplicationInstance.CompleteRequest

如果您想在自己的网站上显示PDF，可以使用以下几个javascript工具来帮助您完成此操作：

https://github.com/mozilla/pdf.js/

就个人而言，我没有使用这些工具中的任何一种，但它们似乎足以满足您的目标。
