示例

下面的代码示例使用 FromOACurrency 方法将包含 OLE 自动化货币值的 Int64 字段转换为等效的 Decimal 数字。The following code example uses the FromOACurrency method to convert Int64 fields that contain OLE Automation Currency values to the equivalent Decimal numbers.

// Example of the Decimal::FromOACurrency method. 
using namespace System;
#define dataFmt "{0,21}{1,25}"

// Display the Decimal::FromOACurrency parameter and Decimal result.
void ShowDecimalFromOACurrency( __int64 Argument )
{
   Decimal decCurrency = Decimal::FromOACurrency( Argument );
   Console::WriteLine( dataFmt, Argument, decCurrency );
}

int main()
{
   Console::WriteLine( "This example of the "
   "Decimal::FromOACurrency( ) method generates \nthe "
   "following output. It displays the OLE Automation "
   "Currency \nvalue as an __int64 and the result as a "
   "Decimal.\n" );
   Console::WriteLine( dataFmt, "OA Currency", "Decimal Value" );
   Console::WriteLine( dataFmt, "-----------", "-------------" );
   
   // Convert OLE Automation Currency values to Decimal objects.
   ShowDecimalFromOACurrency( 0L );
   ShowDecimalFromOACurrency( 1L );
   ShowDecimalFromOACurrency( 100000L );
   ShowDecimalFromOACurrency( 100000000000L );
   ShowDecimalFromOACurrency( 1000000000000000000L );
   ShowDecimalFromOACurrency( 1000000000000000001L );
   ShowDecimalFromOACurrency( Int64::MaxValue );
   ShowDecimalFromOACurrency( Int64::MinValue );
   ShowDecimalFromOACurrency( 123456789L );
   ShowDecimalFromOACurrency( 1234567890000L );
   ShowDecimalFromOACurrency( 1234567890987654321 );
   ShowDecimalFromOACurrency( 4294967295L );
}
