How to view PDF file before downloading

Question

Dear code master, I believe you all doing well.

I am writing an application where I uploaded a pdf file as varbinary(Max) this work file.

I want the user to view the pdf file first before downloading, when I run the application and click the button I get the pdf viewer inline but it display’s “Failed to load PDF document”.

My code is shown below:

var DT = new DataTable();
       DT = ConnectAll.DownloadFile(TextBox1.Text.Trim());
       foreach (DataRow r in DT.Rows)
       {
           byte[] myFile = (byte[])r["docu"];
           Response.Clear();
           Response.Buffer = true;

           Response.ContentType = "application/pdf";
           Response.AddHeader("content-disposition", "inline;filename=MME.pdf");

           Response.Charset = "";
           Response.Cache.SetCacheability(HttpCacheability.NoCache);
           Response.BinaryWrite(myFile);

           Response.End();
       }

Can anybody help me ?

Thank you all
