I have base64 data which i am getting from SOAP. I need to convert that base64 code to pdf and display in popupwindow.

if i convert base64 normally it will be in multipage tiff. sometimes it will be jpg, png. So i can't predict format. I have used following code which will convert from base64 to original format. but notsure how to display it in pop up box. whenever i clicked the button which will call below function, file will get downlaod into local machine. i don't want to download, need to display.

Any suggestion will be appreciated.

In C#
var byteA =
@"base64string ";
var imageBytes = Convert.FromBase64String(byteA);
return File(imageBytes, "application /pdf");
In MVC
@Html.ActionLink("View Image", "PdfPartial")

no issues
just use below code
//c#

byte[] data = Convert.FromBase64String(byteA);

ViewBag.Base64String = "data:application/pdf;base64," + Convert.ToBase64String(data , 0, data.Length);



// in modal  MVC

"@ViewBag.Base64String" width="600" height="500" alt="pdf" pluginspage="http://www.adobe.com/products/acrobat/readstep2.html">

as you described, you are already able to download pdf but you want to display it in modal popup.
then use below code
C#

ViewBag.Base64String = "data:application/pdf;base64," + Convert.ToBase64String(byteA.Data, 0, byteA.Data.Length);



// in modal  MVC

"@ViewBag.Base64String" width="600" height="500" alt="pdf" pluginspage="http://www.adobe.com/products/acrobat/readstep2.html">

Hi,
Please use this one,
byte[] byteInfo =Convert.FromBase64String(base64BinaryStr);
workStream.Write(byteInfo, 0, byteInfo.Length);
workStream.Position = 0;

return new FileStreamResult(workStream, "application/pdf");
