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

パラメーター

value
Decimal Decimal Decimal Decimal

変換する 10 進数。The decimal number to convert.

戻り値

value と等価の OLE オートメーション値を格納する 64 ビット符号付き整数。A 64-bit signed integer that contains the OLE Automation equivalent of value.

次のコード例ではToOACurrency 、メソッドをDecimal使用して、フィールドにInt64含まれる同等の OLE オートメーション通貨値に数値を変換します。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 )
