As per my understanding of your question you are trying open the file means you are trying to launch the file If i am right use this

System.Diagnostics.Process.Start(@"Your_PDF_File_Path");

Edit:Here is an easy option for displaying pdf file in html5.

<embed src="Your_File.pdf" width="800px" height="2100px">
