+In this example, the regular expression pattern `^[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}$` is used, which better reflects common email rules by excluding invalid characters like commas. The regular expression is compiled using the <xref:System.Text.RegularExpressions.RegexOptions.IgnoreCase?displayProperty=nameWithType> flag.
