Gibt zurück
Eine 64-Bit-Ganzzahl mit Vorzeichen, die den entsprechenden Wert von value für die OLE-Automatisierung enthält.
Beispiele
Im folgenden Codebeispiel wird die ToOACurrency -Methode verwendet, um Decimal Zahlen in die entsprechenden OLE Automation Currency-Werte zu konvertieren, die in Feldern enthalten Int64 sind.
// Example of the Decimal::ToOACurrency method.
using namespace System;
#define dataFmt "{0,31}{1,27}"
// Get the exception type name; remove the namespace prefix.
String^ GetExceptionType( Exception^ ex )
{
String^ exceptionType = ex->GetType()->ToString();
return exceptionType->Substring( exceptionType->LastIndexOf( '.' ) + 1 );
}
// Display the Decimal::ToOACurrency parameter and the result
// or exception.
void ShowDecimalToOACurrency( Decimal Argument )
{
// Catch the exception if ToOACurrency( ) throws one.
try
{
__int64 oaCurrency = Decimal::ToOACurrency( Argument );
Console::WriteLine( dataFmt, Argument, oaCurrency );
}
catch ( Exception^ ex )
{
Console::WriteLine( dataFmt, Argument, GetExceptionType( ex ) );
}
}
int main()
{
Console::WriteLine( "This example of the "
"Decimal::ToOACurrency( ) method generates \nthe "
"following output. It displays the argument as a "
"Decimal \nand the OLE Automation Currency value "
"as an __int64.\n" );
Console::WriteLine( dataFmt, "Argument", "OA Currency or Exception" );
Console::WriteLine( dataFmt, "--------", "------------------------" );
