Konvertiert den angegebenen Decimal-Wert in den entsprechenden Currency-Wert für OLE-Automatisierung, der in einer 64-Bit-Ganzzahl mit Vorzeichen enthalten ist.

public:
 static long ToOACurrency(System::Decimal value);

public static long ToOACurrency (decimal value);

static member ToOACurrency : decimal -> int64

Public Shared Function ToOACurrency (value As Decimal) As Long

Parameter

value: Decimal

Die zu konvertierende Dezimalzahl.

Gibt zurück

Int64

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 "

   Console::WriteLine( dataFmt, "Argument", "OA Currency or Exception" );
   Console::WriteLine( dataFmt, "--------", "------------------------" );
   
   // Convert Decimal values to OLE Automation Currency values.
