Ad Alanı:

System.Globalization

Bütünleştirilmiş Kod:

System.Runtime.dll

Kaynak:

NumberFormatInfo.cs

Değerleri geçerli kültüre göre biçimlendiren salt okunur NumberFormatInfo bir değer alır.

public:
 static property System::Globalization::NumberFormatInfo ^ CurrentInfo { System::Globalization::NumberFormatInfo ^ get(); };

public static System.Globalization.NumberFormatInfo CurrentInfo { get; }

static member CurrentInfo : System.Globalization.NumberFormatInfo

Public Shared ReadOnly Property CurrentInfo As NumberFormatInfo

Özellik Değeri

NumberFormatInfo

Geçerli iş parçacığının kültürüne dayalı salt NumberFormatInfo okunur.

Örnekler

Aşağıdaki örnekte ve CultureInfo.CurrentCulture.NumberFormat özellikleri tarafından CurrentInfo döndürülen nesnelerin aynı olduğu gösterilmektedir. Ardından, geçerli kültürü en-US olan bir sistemde özelliği tarafından döndürülen nesnenin CurrentInfo özellik değerlerini NumberFormatInfo görüntülemek için yansımayı kullanır.
