要传递的日志记录。
如果应忘记传递的记录，为 true；否则为 false。
下面的代码示例演示此方法的实现。
public:
virtual bool AbortRecord(LogRecord^ log) override
{
// Check the validity of the record.
if (log == nullptr)
{
return true;
}
array<Object^>^ record = dynamic_cast<array<Object^>^>(log->Record);
if (record == nullptr)
{
return true;
}
if (record->Length != 2)
{
return true;
}
// Extract old account data from the record.
String^ filename = (String^) record[0];
int balance = (int) record[1];
// Restore the old state of the account.
WriteAccountBalance(filename, balance);
return false;
}

public override bool AbortRecord (LogRecord log)

// Extract old account data from the record.
string filename = (string) record[0];
