解析int

Question

当我试图在实体框架上保存一个int值时，我得到了以下错误 -

  

System.OverflowException：＆＃39;值太大或太小   一个Int32。＆＃39;

注意该值类似于 - 9093739202727

有没有更好的方法来处理这个值？

代码：

if (result.responseCode.ToString() == "APPROVED")
{
    var sub = new Subscriptions();
    sub.UserEmail = result.merchantOrderId;
    sub.SaleNumber = Int32.Parse(result.orderNumber.ToString());
    sub.LastTransectionId = Int32.Parse(result.transactionId.ToString());
    sub.LastUpdatedTime = DateTime.Now;
    if (twoCheckout.ProductTypeId == "m")
    {
        sub.ExpirationDate = DateTime.Today.AddMonths(1);
    }else if (twoCheckout.ProductTypeId == "y")
    {
        sub.ExpirationDate = DateTime.Today.AddYears(1);
    }
    sub.Status = false;
    db.Subscriptions.Add(sub);
    db.SaveChanges();
}

C＃的task_limit范围是-2,147,483,648到2,147,483,647。您需要int或更好的long来处理大的值。
