Options for Saving PDFs
How to Save PDF to Disk
Use the PdfDocument.SaveAs method to save your PDF to disk.
You will find that this method supports adding password protection. Check out the following article to learn more about digitally signing exported PDFs: 'Digitally Sign a PDF Document.'
How to Save a PDF File to MemoryStream in C# (System.IO.MemoryStream)
The IronPdf.PdfDocument.Stream property saves the PDF to memory using a System.IO.MemoryStream.
How to Save to Binary Data
The IronPdf.PdfDocument.BinaryData property exports the PDF document as binary data in memory.
This outputs the PDF as a ByteArray, which is expressed in C# as byte [].
How to Serve from a Web Server to Browser
To serve a PDF to the web, we need to send it as binary data rather than HTML.
MVC PDF Export
// Sends 'stream' to the client as a file download with the specified name.
return new FileStreamResult(stream, "application/pdf")
{
FileDownloadName = "file.pdf"
};// Sends 'stream' to the client as a file download with the specified name.
return new FileStreamResult(stream, "application/pdf")
{
FileDownloadName = "file.pdf"
};' Sends 'stream' to the client as a file download with the specified name.
Return New FileStreamResult(stream, "application/pdf") With {.FileDownloadName = "file.pdf"}ASP.NET PDF Export
// Retrieves the PDF binary data
byte[] Binary = MyPdfDocument.BinaryData;
// Clears the existing response content
Response.Clear();
// Sets the response content type to 'application/octet-stream', suitable for PDF files
Response.ContentType = "application/octet-stream";
// Writes the binary data to the response output stream
Context.Response.OutputStream.Write(Binary, 0, Binary.Length);
// Flushes the response to send the data to the client
Response.Flush();// Retrieves the PDF binary data
byte[] Binary = MyPdfDocument.BinaryData;
// Clears the existing response content
Response.Clear();
// Sets the response content type to 'application/octet-stream', suitable for PDF files
Response.ContentType = "application/octet-stream";
// Writes the binary data to the response output stream
Context.Response.OutputStream.Write(Binary, 0, Binary.Length);
// Flushes the response to send the data to the client
Response.Flush();' Retrieves the PDF binary data
Dim Binary() As Byte = MyPdfDocument.BinaryData
' Clears the existing response content
Response.Clear()
' Sets the response content type to 'application/octet-stream', suitable for PDF files
Response.ContentType = "application/octet-stream"
' Writes the binary data to the response output stream
Context.Response.OutputStream.Write(Binary, 0, Binary.Length)
' Flushes the response to send the data to the client
