无法将字符串识别为DateTime.ParseExact的有效参数

问题描述

我正在使用以下代码：

var sec = "163516";
TimeSpan time = TimeSpan.FromSeconds(double.Parse(sec));
DateTime butikDatetime = DateTime.Today.Add(time);
string dateTime = butikDatetime.ToString("dd-MM-yy HH:mm:ss");
DateTime date = DateTime.ParseExact(dateTime, "dd-MM-yy HH:mm:ss", System.Globalization.CultureInfo.InvariantCulture);

但是收到ParseExact错误：

But receive this error for ParseExact:

有人知道出什么问题了？

Somebody have an idea what is wrong?

推荐答案

您正在将 butikDateTime 转换为没有文化的dateTime对象（框架将使用当前的线程区域性），并在以后重新转换使用不变式区域性。您可以在将butikDateTime转换为字符串时使用不变文化吗？

You are converting the butikDateTime to dateTime object without culture (framework will use the current thread culture) and later reconverting the using Invariant culture. Can you use Invariant culture while converting butikDateTime to string

var sec = "163516";
TimeSpan time = TimeSpan.FromSeconds(double.Parse(sec));
DateTime butikDatetime = DateTime.Today.Add(time);
string dateTime = butikDatetime.ToString("dd-MM-yy HH:mm:ss", System.Globalization.CultureInfo.InvariantCulture);
DateTime date = DateTime.ParseExact(dateTime, "dd-MM-yy HH:mm:ss", System.Globalization.CultureInfo.InvariantCulture);

将第3行更新为：

string dateTime = butikDatetime.ToString("dd-MM-yy HH:mm:ss", System.Globalization.CultureInfo.InvariantCulture);
