    int           number = 123;

// Append two lines 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.");
