Converts the specified Decimal value to the equivalent OLE Automation Currency value, which is contained in a 64-bit signed integer.
public:
static long ToOACurrency(System::Decimal value);public static long ToOACurrency (decimal value);static member ToOACurrency : decimal -> int64Public Shared Function ToOACurrency (value As Decimal) As LongParameters
- value
- Decimal
The decimal number to convert.
Returns
A 64-bit signed integer that contains the OLE Automation equivalent of value.
Examples
The following code example uses the ToOACurrency method to convert Decimal numbers to the equivalent OLE Automation Currency values that are contained in Int64 fields.
// 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, "--------", "------------------------" );
