Suppose you have PDF file in you’re App_Data folder. Now follow the step to show the PDF file in your asp.net application.

Step 1:

In this step we will add PDF file in our App_Data folder.

Step 2:

In this step we will add a new asp.net page on which we will display the App_Data folder.

Step 3:

Follow the below mention code to convert the PDF file into Byte array string.

public void     PDFDisplay()         {             string fileFolderPath = "~/App_Data/professional-cloud-architect.pdf ";             String file = Convert.ToBase64String(File.ReadAllBytes(Server.MapPath(fileFolderPath)));             byte[] bytes = Convert.FromBase64String(bytePDF);             Response.Clear();             Response.ContentType = "application/pdf";             Response.Buffer = true;                Response.Cache.SetCacheability(HttpCacheability.NoCache);             Response.BinaryWrite(bytes);             Response.End();             Response.Close();         }

 

Here in above code I have first stored the App_Data folder file path in a string variable and after that converted it into base64bit string.

Now through the Response.BinaryWrite function the PDF file file have been displayed on the screen. Now run the application and check the output.
