Açıklamalar

Tüm ToString yöntemlerde olduğu gibi, çıkış .NET Framework sürümleri arasında tutarlı olmayabilir, bu nedenle yöntem sonuçları içerik için ayrıştırılmamalıdır. İçerik hakkında kesin bilgi edinmek için nesnedeki X509Certificate2 özellikleri kullanın veya sertifika hakkında bilgi almak için yöntemini kullanın ToString .

Bu yöntem sertifikayı metin biçiminde görüntüler.

ToString(Boolean)
