Solution 1

Well, no - it won't.
Look at your code:

C#

var myMemoryStream = new MemoryStream();
Response.Clear();
 Response.ContentType = "Application/msword";
 Response.AddHeader("Content-Disposition";"attachment;filename=" + strFilename);
 Response.BinaryWrite(myMemoryStream.ToArray());

myMemoryStream is new, so contains no data - so the system (correctly) transfers no bytes...and that means no download.

Perhaps you forgot to load the MemoryStream with data from a file or database somewhere?

byte[] file = File.ReadAllBytes(filename);
var myMemoryStream = new MemoryStream(file);
Response.ContentType = "Application/msword";

This may sound like a silly question, but did you look at your code?
You read a file into an array of bytes, in order to convert it to a stream, and convert that back to an array of bytes in order to send it to the client... Why?

And then, you close the HttpResponse... which throws everything away:
"This method terminates the connection to the client in an abrupt manner and is not intended for normal HTTP request processing. The method sends a reset packet to the client, which can cause response data that is buffered on the server, the client, or somewhere in between to be dropped."
MSDN: http://msdn.microsoft.com/en-us/library/system.web.httpresponse.close(v=vs.110).aspx

So, read the file, send the bytes directly to the client, and don't close the response!

Solution 3

string filename = Server.MapPath("~/File/DocFile/") + strFilename;
Response.Redirect("~/File/DocFile/" + strFilename);

these two lines r enough to download a file from your location.

thanks to
