我最近聆听了Kevin Hazzard在www.Net Rocks显示570()上的讲话。 他提到,使长期合同检查成为一种选择,一些人可能选择使用,而其他人可能不使用。
为什么你不使用《规则》合同的长期合同检查? 对业绩是否有重大的负面影响? 其他原因?
如果你能改变这一特点,你如何在日常工作中处理前提条件?
在某些非任务关键应用中,你可能实际上想让释放工作中的错误lide倒,而不是在使用者面前 throw错。 终端用户可能永远不会注意到的小ug可能会导致你的合同检查失败,并损害用户的经验。
在我看来,使用合同和<>>/em”另一种先决条件检查形式,因为你最终会重复你的前提条件。
使用合同检查你,迫使客户有。 净额4.或以上——就业绩而言,虽然我无法想象这是一个问题,但你最好在作出决定之前对其进行测试。
在许多情况下,如果你想从例外情况中恢复,那么你需要详细了解造成这种情况的原因——这通常涉及创建你自己的例外类别,并作为财产证明你的细节。 使用最基本的例子:<代码> ArgumentOutOfRangeException 载有财产<>code>ActualValue,你可以读出,并根据你的价值决定做些什么。
在使用合同时,如果你的合同失败,就只给你一个基本的<代码>ContractException,该编码是编造的,而且只包含有关合同以示形形式失败的细节,这可能需要一些复杂的平价,才能从中提取你想要的东西——一般而言,你会让双方这样做。
如果你利用自己的例外,就没有理由将合同暂时搁置起来,因为如果合同要失败,就永远不会达到合同损失,那么你只是用不了的指示。
采用静态合同检查以及你自己的例外检查,是消除错误的最有效形式。 大部分时间,你们的例外情况永远不会被thrown弃,因为你再次告诉我们,如何解决问题,然后才能掌握你的意见。
