Açıklamalar

16 ise fromBase , parametresi tarafından value belirtilen sayıyı "0x" veya "0X" ön ekiyle belirtebilirsiniz.

UInt32 Veri türü yalnızca imzasız değerleri desteklediğindenToUInt32(String, Int32), yöntemi bunun value imzasız ikili gösterim kullanılarak ifade edildiği varsayılır. Başka bir deyişle, sayısal değeri temsil etmek için tüm 32 bit kullanılır ve bir işaret biti yoktur. Sonuç olarak, yöntem özel durum oluşturmadan veri türü aralığının dışında olan imzalı bir tamsayı değerinin UInt32 bir UInt32 değere dönüştürüldüğü kod yazmak mümkündür. Aşağıdaki örnek onaltılık dize gösterimine dönüştürür MinValue ve yöntemini çağırır ToUInt32(String, Int32) . Yöntemi özel durum atmak yerine "0x80000000 2147483648 dönüştürür" iletisini görüntüler.

// Create a hexadecimal value out of range of the UInt32 type.
string value = Convert.ToString(Int32.MinValue, 16);
// Convert it back to a number.

İkili işlemler veya sayısal dönüştürme işlemlerini gerçekleştirirken, bir yöntem veya işlecin belirli bir değeri yorumlamak için uygun sayısal gösterimi kullandığını doğrulamak her zaman geliştiricinin sorumluluğundadır. Aşağıdaki örnekte, yöntemin onaltılık dizeyi bir değere dönüştürürken ikinin tamamlayıcı gösterimini kullanan bir değeri yorumlamak için ikili gösterimi uygunsuz kullanmamasını sağlamaya yönelik bir UInt32 teknik gösterilmektedir. Örnek, dize gösterimine dönüştürme sırasında bir değerin bir işaretli veya işaretsiz bir tamsayı temsil edip etmediğini belirler. Örnek değeri bir UInt32 değere dönüştürdüğünde, özgün değerin imzalı bir tamsayı olup olmadığını denetler. Bu durumda ve yüksek sıralı biti ayarlanırsa (özgün değerin negatif olduğunu gösterir), yöntem bir özel durum oluşturur.

Aşağıdaki örnek, bayt dizisindeki her öğeyi işaretsiz bir tamsayıya dönüştürür.

byte[] bytes = { Byte.MinValue, 14, 122, Byte.MaxValue};
uint result;

foreach (byte byteValue in bytes)

   result = Convert.ToUInt32(byteValue);
   Console.WriteLine("Converted the {0} value {1} to the {2} value {3}.",

//    Converted the Byte value 255 to the UInt32 value 255.

Aşağıdaki örnek Boole değerlerini ve false işaretsiz tamsayılara true dönüştürür.
