C# 在C中解析JS Date.toIsoString#

我需要将JS日期存储为ISO 8601日期。我目前从一个格式为2019-06-22T00:00:00.000Z的表单中获取日期，正如JS'toIsoString（）方法所预期的那样

当这个日期被传递给我的API控制器时，我已经尝试在这个日期使用DateTime.ParseExact并将格式传递给该方法

我试过了

TS

C#

及

哪个扔

我开始觉得这是toIsoString（）的一个问题，但对于DateTimes，我是一个新手，不知道还能从哪里找到答案。还有其他人见过这个吗？日期与格式规则匹配，但似乎无法对其进行解析。

您可以使用

Convert.ToDateTime（）

函数，该函数还接受字符串日期格式值，并将其转换为

C.

List objList=new List（）；
对象列表添加（“2019-06-22T00:00:00.000Z”）；
objList.ForEach（x=>Console.WriteLine（Convert.ToDateTime（x））；

将其放入

try catch

，以便在收到任何无效格式时可以处理异常，将其记录下来以增强调试

有关

Convert.ToDateTime（）的详细信息

下面是如何将从客户端类型脚本接收的字符串值转换为DateTime对象的细节

它会引发什么异常/错误？或者ParseExact在C#中为ShowDate变量赋值了什么？我现在将更新这个问题，以便更清楚地知道在API中抛出了什么以及具体做了什么。我喜欢这个，它完全按照我想要的方式工作。我一直在努力让它工作，在6个月没碰它之后，你在一个小时内就解决了我的问题。非常感谢。很高兴减轻你的痛苦兄弟：P.：）
