Saving an open PDF file using C# Code

Question

Hi. I have an open PDF file. Is it posible using c# code to save it by referencing it without any dialoge box interfering in the way? Thanks Rafael

Hi Brunda Thank you for your reply. I forgot to mention that the file is not yet saved to the disk. It was opened after i clicked Open in the download dialoge box. And then i'd like to save it. Let's say the file name is Report.pdf and that i want to save it on C:\. How do i use the code you provided? Thanks Rafael

public void SaveToOutput(Stream dataStream) { dataStream.Seek(0 SeekOrigin.Begin); FileStream fileout = File.Create(somepath/file.pdf); const int chunk = 512; byte[] buffer = new byte[512]; int bytesread = dataStream.Read(buffer0chunk); while (bytesread == chunk) { HttpContext.Current.Response.OutputStream.Write(buffer 0 chunk); fileout.Write(buffer 0 chunk); bytesread = dataStream.Read(buffer 0 chunk); } HttpContext.Current.Response.OutputStream.Write(buffer 0 bytesread); fileout.Write(buffer 0 bytesread); fileout.Close(); HttpContext.Current.Response.ContentType = application/pdf; }
