捕获交易错误

Question

当我发布输入错误（例如错误的cvv）的事务时，将引发实际的C＃异常，并且响应为null。因此，我显然无法访问“错误”列表。为什么有更好的方法来捕获错误然后解析Message值？

try
{
    sqResponse = transactionsApi.Charge(tokenInfo.LocationID, chargeRequest);
}
catch (SquareUp.Client.ApiException e)
{
    if (e.Message.Contains("VERIFY_CVV_FAILURE")) { error = "CVV is incorrect."; }
    else if (e.Message.Contains("VERIFY_AVS_FAILURE")) { error = "Postal Code is incorrect."; }
    else if (e.Message.Contains("INVALID_EXPIRATION")) { error = "Expiration date is incorrect."; }
    else if (e.Message.Contains("CARD_DECLINED")) { error = "Credit card has been declined."; }
    else if (e.Message.Contains("INVALID_CARD")) { error = "Credit card number is not valid"; }
    else
    {
     error = e.ErrorCode.ToString();        
    }

    return false;
}

我的错误。当然，返回的错误列表是在客户端调用的json结果中返回的。 Errors
