I have this question and I am not able to figure it out.

Bulk Download:

The application should provide a bulk download facility as follows. The user should be able specify a file name, default setting bulk.txt, containing URLs (exactly one per line).

When initiating bulk download, the application should retrieve each of the pages listed in the file, and display the results as a list of lines as follows: code bytes URL

where code should be the response status code from the page retrieval, bytes should be the number of bytes retrieved from this URL, and URL should be the URL as specified in the bulk download file.

These results should be shown in a textarea.

What I have tried:

I have manged to do this but I don't think I know how to display it.

Bulk.txt has 5 lines of text with some website URL's

private async void button2_Click(object sender, EventArgs e)
       {
           string path = "C:bulk.txt";
           StreamReader stream = new StreamReader(path);
           string mydata = stream.ReadToEnd();
          label1.Text = mydata.ToString();
           stream.Close();


           using (var client = new HttpClient())
           using (HttpResponseMessage response = await client.GetAsync("https://www.google.com"))
           {
               byte[] fileContents = await response.Content.ReadAsByteArrayAsync();
               richTextBox1.Text = fileContents.ToString();
           }
       }

You read the text file's content but then do not use those URLs as specified in the instructions.

Also look at the following:
          string mydata = stream.ReadToEnd();
          label1.Text = mydata.ToString();
 

Why are you calling ToString on a value that is already a string?

The instructions are clear:
- Read each line from the text file one at a time.
- Use the URL just read to capture some data from the internet.
- Display the HTTP status code, the number of bytes returned and the URL.
- Repeat until all lines processed.

I do not know how to get the number of bytes returned and display it

You need to examine the response returned from each HTTP request.

Currently I tried from a single request like google.com but it displays System.bytes[] in my textbox.

You need to convert the contents to its string representation by the use of the Encoding Class (System.Text) | Microsoft Docs[^]. But you should not really be doing this, the instructions tell you just to print the status code, and the number of bytes returned. The actual response text will be a few pages long.
