使用sonarqube分析我的代碼并被告知“'actor'在至少一個執(zhí)行路徑上為空”以下代碼if (actor.ProducerAgreementIds != null && actor.ProducerAgreementIds.Count > 0)
{actor.ProducerAgreementIds是一個List<string>。這條語句不是已經(jīng)在執(zhí)行空檢查了嗎？或者它應(yīng)該是：if (actor != null && (actor.ProducerAgreementIds != null && actor.ProducerAgreementIds.Count > 0))
{替代方案將只使用條件訪問if (actor?.ProducerAgreementIds != null && actor.ProducerAgreementIds.Count > 0)適當(dāng)且不會引起下游問題？謝謝！

通過此驗證就足夠了：
if (actor?.ProducerAgreementIds?.Count > 0)
