Örnekler

Aşağıdaki örnek, negatif işaretini "~" dizesi ve pozitif işaretini "!" dizesi olarak tanımlayan özel NumberFormatInfo bir sınıf tanımlar. Ardından bir tamsayı dizisindeki her öğeyi eşdeğer dize gösterimine dönüştürmek için yöntemini çağırır ToString(Int32, IFormatProvider) . Dönüştürme, sabit kültürün yanı sıra özel NumberFormatInfo nesneyi de kullanır.

int[] numbers = { Int32.MinValue, Int32.MaxValue};
System.Globalization.NumberFormatInfo nfi = new System.Globalization.NumberFormatInfo();
nfi.NegativeSign = "~";
nfi.PositiveSign = "!";

foreach (int number in numbers)
   Console.WriteLine("{0,-12}  -->  {1,12}",
                     Convert.ToString(number, System.Globalization.CultureInfo.InvariantCulture),
                     Convert.ToString(number, nfi));
// The example displays the following output:

Açıklamalar

value Pozitifse ve toBase 2, 8 veya 16 ise, döndürülen dizede işaret ve büyüklük gösterimi kullanılır. value Negatifse ve toBase 2, 8 veya 16 ise, döndürülen dize ikinin tamamlayıcı gösterimini kullanır. Bu, yüksek sıralı baytın (bit 15) yüksek sıra bitinin işaret biti olarak yorumlandığı anlamına gelir. ToString(Int16, Int32) Daha sonra bir sayıya geri dönüştürülecek bir dize oluşturmak için yöntemi çağrılırsa, dönüştürmeyi gerçekleştirmek için benzer bir sayısal gösterim varsayan ilgili bir yöntem çağrılmalıdır. Bu tür yöntemler arasında ve Int16.Parse(String, NumberStyles)bulunurConvert.ToInt16(String, Int32).

Açıklamalar

value Pozitifse ve toBase 2, 8 veya 16 ise, döndürülen dizede işaret ve büyüklük gösterimi kullanılır. value Negatifse ve toBase 2, 8 veya 16 ise, döndürülen dize ikinin tamamlayıcı gösterimini kullanır. Bu, en yüksek sıralı baytın (bit 31) yüksek sıra bitinin işaret biti olarak yorumlandığı anlamına gelir. ToString(Int32, Int32) Daha sonra bir sayıya geri dönüştürülecek bir dize oluşturmak için yöntemi çağrılırsa, dönüştürmeyi gerçekleştirmek için benzer bir sayısal gösterim varsayan ilgili bir yöntem çağrılmalıdır. Bu tür yöntemler arasında ve Int32.Parse(String, NumberStyles)bulunurConvert.ToInt32(String, Int32).

Açıklamalar

value parametresi arabirimini IConvertible uygularsa, yöntemi uygulamasını valueçağırırIConvertible.ToString(IFormatProvider). Aksi takdirde, parametresi arabirimini uygularsa valueIFormattable , yöntemi onun IFormattable.ToString(String, IFormatProvider) uygulamasını çağırır. Herhangi bir arabirim uygulanmazsa value , yöntemi parametresinin valueToString() yöntemini çağırır ve provider parametresi yoksayılır.

provider parametresi veya IFormattable arabirimini value uyguluyorsa IConvertible parametresi kullanılır. parametresinin provider en yaygın kullanımı, dönüştürmesinde kullanılan kültüre özgü bilgileri belirtmektir value. Örneğin, parametre negatif bir ondalık sayıysa value , provider parametre negatif işareti ve ondalık ayırıcısı için kullanılan gösterimi hakkında kültüre özgü bilgiler sağlayabilir. Sonraki bölümdeki ikinci örnekte kültüre duyarlı biçimlendirme bilgileri vermeyen bir biçim sağlayıcısı gösterilmektedir.

Açıklamalar

value Pozitifse ve toBase 10 değilse, döndürülen dize sign-and-magnide gösterimini kullanır. Negatifse value ve toBase 10 değilse, döndürülen dize ikinin tamamlayıcı gösterimini kullanır. Bu, en yüksek sıralı baytın (bit 63) yüksek sıra bitinin işaret biti olarak yorumlandığı anlamına gelir. ToString(Int64, Int32) Daha sonra bir sayıya geri dönüştürülecek bir dize oluşturmak için yöntemi çağrılırsa, dönüştürmeyi gerçekleştirmek için benzer bir sayısal gösterim varsayan ilgili bir yöntem çağrılmalıdır. Bu tür yöntemler arasında ve Int64.Parse(String, NumberStyles)bulunurConvert.ToInt64(String, Int32).
