如何将 SQL 日期时间戳从 Bigint 格式化为 C# 日期

Question

I need to convert dates in an SQL view from BIGINT value (format: 20220504112601755 ) to C# date time value (to some similar format: 2022.05.04 11:26:01 ) within C#.

All I found were unix epoch times and how to convert those to readable date times but not much about my issue.

Any help would be appreciated. (Didn't include any code because nothing I tried even came close to working as I wanted)

Thanks

您需要使用DateTime ParseExact方法，例如：

var date = DateTime.ParseExact("20220504112601755", "yyyyMMddhhmmssfff", System.Globalization.CultureInfo.InvariantCulture);
