It looks like `window.open` will take a Data URI as the location parameter.

So you can open it like this from the question: [Opening PDF String in new window with javascript][Open PDF]:



    window.open("data:application/pdf;base64, " + base64EncodedPDF);

Here's an [runnable][0] [example in plunker][1], and [sample pdf file][2] that's already base64 encoded.


Then on the server, you can convert the byte array to base64 encoding like this:



    string fileName = @"C:\TEMP\TEST.pdf";
    byte[] pdfByteArray = System.IO.File.ReadAllBytes(fileName);
    string base64EncodedPDF = System.Convert.ToBase64String(pdfByteArray);

**NOTE**: This seems difficult to implement in IE because the URL length is prohibitively small for sending an entire PDF.

Based on the question [Open PDF in new browser full window][PDF JavaScript], it looks like I can use JavaScript to open a new window with a PDF file with the following code:



    window.open('MyPDF.pdf', '_blank');

I'd like to do so on a return trip from the server by adding a byte array instead of the file name to use as the URL location in [`window.open`][window.open]

I'm currently returning PDF files like [this][PDF Response]:



    Response.Clear();
    Response.ContentType = "application/pdf";
    Response.BinaryWrite(pdfByteArray);
    Response.Flush();

Is there a way to open a new window with a PDF byte array in javascript.  

Something like this:



    var script = "window.open('" + pdfByteArray + "', '_blank');";
    ScriptManager.RegisterClientScriptBlock(Parent.Page, typeof(Page), "pdf", script, true);
