Question

I m developing an application that reads files from a remote server and copies it onto the local drive.

The code I m using to read and write the file is –

string saveTo1 = savePath + @"\" + filename[i];
                byte[] buffer = new byte[32768];
                using (Stream input = getResponse.GetResponseStream())
                {
                    using (FileStream output = new FileStream(saveTo1, FileMode.OpenOrCreate))
                    {
                        int bytesRead;

                        while ((bytesRead = input.Read(buffer, 0, buffer.Length)) > 0)
                        {
                            output.Write(buffer, 0, bytesRead);
                        }
                        output.Close();
                    }
                }

How can I create a log file that keeps track of the details of file copy and also records if there is any error while copying the files?

Thanks in advance 🙂

You can log in different ways.

• EventLogger (as already suggested)
• Custom file log (as already
  answered)
• Log Engine: I suggest you
  log4net. It’s very powerfull
  and highly customizable.

Any way, I would shape the code in this way, where MyLogManager implement one of the previous solutions:

string saveTo1 = savePath + @"\" + filename[i];
byte[] buffer = new byte[32768];
try
{
            using (Stream input = getResponse.GetResponseStream())
            {
                using (FileStream output = new FileStream(saveTo1, FileMode.OpenOrCreate))
                {
                    int bytesRead;

                    while ((bytesRead = input.Read(buffer, 0, buffer.Length)) > 0)
                    {
                        output.Write(buffer, 0, bytesRead);
                    }
                    output.Close();
                }
            }
    //logging good news and info
    MyLogManager("Good news", FileDetails);
}
catch(Exception ex)
{
    //logging bad news and exceptions info
    MyLogManager("Bad news", ExceptionDetails);
}
