Problem about downloading a text file in ASP.NET?

Hi ,

I should create a .txt file dynamically . After the text file is created, it should be downloaded by the user. For this purpose , I try the code (I simplified the code basically like below ):

C#

string blabla= "Hello World";
Response.Clear();
Response.ContentType = "text/plain";
Response.AddHeader("Exported text File", "attachment; filename=helloWorld.txt");
Response.ContentEncoding = Encoding.Default;
byte[] bytes = Encoding.Default.GetBytes(blabla);
Response.BinaryWrite(bytes);
Response.End();

But this code block behaves like Response.Write() . The content is written at the download page. There is no file to be downloaded.

Thanks for the replies in advance..

Solution 1

Try adding Content-Disposition in header.
Try this:

C#

string blabla = "Hello World";
Response.Clear();
Response.ContentType = "text/plain";
//Response.AddHeader("Exported text File", "attachment; filename=helloWorld.txt");
Response.AddHeader("Content-Disposition", String.Format("attachment;filename=helloWorld.txt"));
Response.ContentEncoding = Encoding.Default;
byte[] bytes = Encoding.Default.GetBytes(blabla);
Response.BinaryWrite(bytes);
Response.End();

Thanks for the reply :)
It works well, by the way what is the difference of "Content-Disposition" in header?

It forces the browser to open save as dialogue with the attached file. Refer here[^].
