Stringbuilder to CSV

Question

I have the following Problem, I'm trying to get the Content from my StringBuilder to my .csv File:

public String GetCSV()
            {
                System.Text.StringBuilder sb = new StringBuilder();

                sb.Append(m_ID.ToString());
                sb.Append(";");
                sb.Append(m_Starttime.ToString());
                sb.Append(";");
                sb.Append(m_EndTime.ToString());
                sb.Append(";");
                sb.Append(m_IsSerie.ToString());
                sb.Append(";");
                sb.Append(m_Title);
                sb.Append(";");
                sb.Append(m_Description);
                sb.Append(";");
                sb.Append(m_Lastchange.ToString());
                sb.Append(";");

                return sb.ToString();
                WriteCSV();
            }


        public void WriteCSV()
        {                
            string csvpath = @"c:\Temp\Kalender.csv";

            if (File.Exists(csvpath))
            {
                File.Delete(csvpath);
            }

                using (StreamWriter sw = File.CreateText(csvpath))
                {
                    foreach (string CalendarItem in CalendarItem)
                    {
                        if (sb.Length > 0)
                            sb.Append(", ");

                        sb.Append(part);
                    }

                }

        }

Now I know how to create the CSV File already but I have no idea how I could fill it with my Content from the StringBuilder I'm sure that'll be handled by an foreach Loop right?

Solution

I would use StringBuilder AppendLine to create new line and than write the complete StringBuilder to the file-system with File.WriteAllText. Take a look at AppendLine

Also, WriteCSV(); will never be executed, because you have a return before.
