Özel durumlar

Örnekler

Aşağıdaki örnek, birkaç tarih ve saat değerinin dize gösterimini şu şekilde ayrıştırır:

• Örnek çıkışı oluşturmak için kullanılan bilgisayarın geçerli kültürünün biçimlendirme kurallarını sağlayan varsayılan biçim sağlayıcısını kullanma. Bu örnekteki çıktı, en-US kültürünün biçimlendirme kurallarını yansıtır.

• AllowWhiteSpacesvarsayılan stil değerini kullanma.

Yöntem başka bir kültürün biçimlendirme kurallarını kullanarak bir tarih ve saatin dize gösterimini ayrıştırmaya çalıştığında oluşan FormatException özel durumunu işler. Ayrıca geçerli kültürün biçimlendirme kurallarını kullanmayan bir tarih ve saat değerinin nasıl başarıyla ayrıştırıldığını da gösterir.

Bu aşırı yükleme, geçerli kültürün biçimlendirme kurallarını kullanarak s ayrıştırmaya çalışır. Geçerli kültür CurrentCulture özelliğiyle gösterilir. Belirli bir kültürün biçimlendirme kurallarını kullanarak bir dizeyi ayrıştırmak için Parse(String, IFormatProvider) veya Parse(String, IFormatProvider, DateTimeStyles) aşırı yüklemelerini çağırın.

Bu aşırı yükleme, DateTimeStyles.AllowWhiteSpaces stili kullanarak s ayrıştırmaya çalışır.
