Saving a string into a new file

[mbewers1]

I'm writing code to perform a rather simple task but it appears to be more difficult than it should be. I have a fileContent string, containing a long string item, which I have generated within my code and wish to save and a path variable which contains the new path I wish to save the file to.

/*
     * Process of exporting file to save it as a single document, ensuring
     * that the correct extension is used.
     */ 
    private void ExportToSave(string path, string fileContent)
    {
        HttpResponse hr = HttpContext.Current.Response;
        hr.AddHeader("Content-Disposition", "attachment;filename=ProRefExport");
 
        StreamWriter sw = new StreamWriter(path);
        HtmlTextWriter htmlWriter = new HtmlTextWriter(sw);
        sw.WriteLine(string.Format("Generated by user on", DateTime.Today));
        sw.Close();
        htmlWriter.Close();
 
        File.WriteAllText(path, fileContent, System.Text.Encoding.ASCII);
 
        hr.ContentType = "text/html";
        hr.End();
 
        base.Render(htmlWriter);
    }
 

When I debug the code, the fileContent variable contains the string in full but, once the file is downloaded and saved, however, there is no text inside it.

I tried writing the fileContent string as an array of bytes using the same StreamReader object I created but made things worse as I had file process errors.

Why might this be and what can I do to solve this problem?

Have you tried putting a breakpoint at line 7 then walk through line by line to see where you get an error?

Line 16 is a File.Write. Have you opened the file with write privileges first someplace? I don't see that.

Yes, I've tried debugging it and the text shows up but no file content is saved.
I didn't realised that properties had to be assigned to a File object, I thought File.Write literally meant make a new file.

Comment: text shows up but no file content is saved.

What does "shows up" mean? Is the text in the file? Isn't that the goal; to make a file that contains your string?

Again I suggest that you open the file for writing before you try to write to it.
