예제

다음 코드 예제에서는 CultureInfo가와 DateTimeFormatInfo 연결 된 및 인스턴스도 복제 함을 보여 줍니다. NumberFormatInfo CultureInfoThe following code example shows that CultureInfo.Clone also clones the DateTimeFormatInfo and NumberFormatInfo instances associated with the CultureInfo.

using namespace System;
using namespace System::Globalization;
int main()
{
   
   // Creates and initializes a CultureInfo.
   CultureInfo^ myCI = gcnew CultureInfo( "en-US",false );
   
   // Clones myCI and modifies the DTFI and NFI instances associated with the clone.
   CultureInfo^ myCIclone = dynamic_cast<CultureInfo^>(myCI->Clone());
   myCIclone->DateTimeFormat->AMDesignator = "a.m.";
   myCIclone->DateTimeFormat->DateSeparator = "-";
   myCIclone->NumberFormat->CurrencySymbol = "USD";
   myCIclone->NumberFormat->NumberDecimalDigits = 4;
   
   // Displays the properties of the DTFI and NFI instances associated with the original and with the clone. 
   Console::WriteLine( "DTFI/NFI PROPERTY\tORIGINAL\tMODIFIED CLONE" );
   Console::WriteLine( "DTFI.AMDesignator\t{0}\t\t{1}", myCI->DateTimeFormat->AMDesignator, myCIclone->DateTimeFormat->AMDesignator );
   Console::WriteLine( "DTFI.DateSeparator\t{0}\t\t{1}", myCI->DateTimeFormat->DateSeparator, myCIclone->DateTimeFormat->DateSeparator );
   Console::WriteLine( "NFI.CurrencySymbol\t{0}\t\t{1}", myCI->NumberFormat->CurrencySymbol, myCIclone->NumberFormat->CurrencySymbol );
   Console::WriteLine( "NFI.NumberDecimalDigits\t{0}\t\t{1}", myCI->NumberFormat->NumberDecimalDigits, myCIclone->NumberFormat->NumberDecimalDigits );
}

설명

원본이 읽기 전용인 경우에도 클론은 쓰기가 가능 합니다 CultureInfo .The clone is writable even if the original CultureInfo is read-only. 따라서 클론의 속성을 수정할 수 있습니다.Therefore, the properties of the clone can be modified.

개체의 단순 복사본에만 개체의 복사본이입니다.A shallow copy of an object is a copy of the object only. 개체에 다른 개체에 대 한 참조가 포함 되어 있으면 단순 복사본은 참조 된 개체의 복사본을 만들지 않습니다.If the object contains references to other objects, the shallow copy does not create copies of the referred objects. 대신 원본 개체를 참조 합니다.It refers to the original objects instead. 반면 개체의 전체 복사본은 개체의 복사본 및 해당 개체에서 직접 또는 간접적으로 참조 하는 모든 항목의 복사본을 만듭니다.In contrast, a deep copy of an object creates a copy of the object and a copy of everything directly or indirectly referenced by that object.

Clone메서드는 향상 된 단순 복사본을 만듭니다.The Clone method creates an enhanced shallow copy. ,, 및 속성에서 반환 하는 개체 NumberFormat DateTimeFormat TextInfo Calendar 도 복사 됩니다.The objects returned by the NumberFormat, DateTimeFormat, TextInfo, and Calendar properties are also copied. 따라서 복제 된 CultureInfo 개체는 원래 개체에 영향을 주지 않고 복사 된 속성을 수정할 수 있습니다 CultureInfo .Consequently, the cloned CultureInfo object can modify its copied properties without affecting the original CultureInfo object.
