I've been looking at examples and not sure if I'm doing this correctly. I want to write errors to a textfile. I want to write to textfile but also display an error msg to user. I think what I have is wrong because what if the file exists...then if statement wont be execuste. This is what I have;

private void SaveRecords()
       //call save routine in Return Class
    catch (Exception ex)
       string path = @"c:\SaveReturnItem.txt";
                if (!File.Exists(path))
                    // Create a file to write to.
                    using (StreamWriter sw = File.CreateText(path))

      MessageBox.Show("Record could not be saved.");

// in Return class

public void Save(...)
    catch (Exception ex)
       throw ex;
