Как и в ToString случае со всеми методами, выходные данные могут быть несогласованными в разных версиях платформа .NET Framework, поэтому результаты метода не должны анализироваться для содержимого.As with all ToString methods, the output might not be consistent across versions of the .NET Framework, so the method results should not be parsed for content. Используйте свойства X509Certificate2 объекта для получения точных сведений о содержимом или используйте ToString метод для получения сведений о сертификате.Use the properties on the X509Certificate2 object to obtain precise information about the content or use the ToString method to obtain information about the certificate.

Этот метод отображает сертификат в текстовом формате.This method displays the certificate in text format.
