[ComVisibleAttribute(false)]
public StringBuilder AppendLine()

      int number = 123;

      // Append two lines of text.
      sb.AppendLine("The first line of text.");
      sb.AppendLine(line);

      // Append a new line, an empty string, and a null cast as a string.
      sb.AppendLine();
      sb.AppendLine("");
      sb.AppendLine((string)null);

      // Append the non-string value, 123, and two new lines.
      sb.Append(number).AppendLine().AppendLine();

      // Append two lines of text.
      sb.AppendLine(line);
      sb.AppendLine("The last line of text.");
