Failed network error while downloading the files from Google Chrome

Question

I written the below c# code for downloading the attachments in my application, when i run the code i can download the files using Mozilla, internet explorer but this is not working in Google Chrome.

string base64FileString = result;
byte[] binaryFile = Convert.FromBase64String(base64FileString);
Response.ContentType = "application/octet-stream";
Response.AddHeader("content-disposition", String.Format("attachment; filename=\"{0}\"", Request.QueryString["FILENAME"]));
Response.Clear();
Response.BufferOutput = false;
Response.ClearContent();
Response.BinaryWrite(binaryFile);
Response.Flush();
Response.Close();

Can anyone please help me what changes need to do for downloading in Chrome

Solution

Google Chrome will not open a "file save" window for you if "application/octet-stream" is your response from a form.

The content-type should be whatever it is known to be, if you know it. E.g. "application/pdf", "image/png" or whatever. See Complete list of MIME types

See this question What could keep Chrome from downloading files? for more information.
