StreamWriter and File Access

[=?Utf-8?B?TWlrZQ==?=]

Hi. I'm building an ASP.NET site which is hosted on a remote server. When I
try to create a new file using StreamWriter I must specify the drive location
where the file will be saved. I don't have file access anywhere on the
remote server, and therefore I can't figure out how I can create a file. Is
it possible to utilize StreamWriter to create a new file and somehow display
it for the user to save, without actually saving the file programatically?
Or is there anyway I can work around this issue?

Thanks all.

What sort of file is that?

Howdy,

Yes, there is. Use combination of Response.BinaryWrite(),
Response.AddHeader(). I posted similar example here: (skip file related code,
and replace Response.WriteFile with Response.BinaryWrite(yourStream))

In case of any issues, let us know.

If it's a StreamWriter, it's probably text. I find that to write text
back directly to the Response this kind of code works well:

StreamReader input = null;
StreamWriter output = null;
try
{
// Clear the response to avoid any unwanted
// additions to the file.
Response.Clear();
output
= new StreamWriter( Response.OutputStream );

Response.ContentType = "text/ascii";

output.WriteLine( "Hello world" );
}
catch ( Exception )
{
// There was an error --clear the response
// and return a HTML formatted error message.
Response.Clear();
Response.ClearHeaders();
Response.ContentType = "text/html";
Response.Write( "We're sorry, there was an error." );
}
finally
{
if ( output != null )
{
// Flush the output stream to avoid losing
// something on the line...
output.Flush();
output.Close();
}
// Flush the response and close it.
Response.Flush();
Response.Close();
Response.End();
}

Hi Laurent,

I hope you are well. I believe he wanted to display 'save as dialog' box
automatically, instead of displaying content that user can copy from window,
that's why i went for Content-Disposition : fileattachement

Respect :)

Hi again,

Actually good call he could just add to your example:
Response.AddHeader("Content-Disposition", "attachment;
filename=\"test.txt\"");

Yes. I had that in my initial draft of the reply first, then I removed
it because it was not clear to me if he wanted the file displayed in the
same window, or with a "Open/Save" dialog.
