示例

下面的代码示例使用 FromOACurrency 方法将包含 Int64 OLE Automation Currency 值的字段转换为等效 Decimal 数字。

// 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 );
