Question

我有一个DateTime.Utcnow，我想转换为本地时间。我想以"dd/MM/yyyy HH:mm"的格式将其转换为本地时间。 ToLocalTime没有它的构造函数。

_executionTimeRepository.SetLastSuccessfulRunDate(DateTime.UtcNow, "FailedJobService");

public void SetLastSuccessfulRunDate(DateTime successfulRunDate, string nameOfService)
{
    using (var context = _contextFactory())
    {
        var field = context.ExecutionTimes.First(s => s.NameOfService == nameOfService);
        field.LastRunDate = successfulRunDate.ToLocalTime();
        context.SaveChanges();
    }
}

Answer 1

如果是String

string date1 = DateTime.UtcNow.ToLocalTime().ToString("dd/MM/yyyy HH:mm");

如果是DateTime

DateTime date2 = DateTime.ParseExact(DateTime.UtcNow.ToLocalTime().ToString("dd/MM/yyyy HH:mm"), "dd/MM/yyyy HH:mm", null);

Answer 2

field.LastRunDate是DateTime还是string？根据类型，请参阅选项：

if DateTime

field.LastRunDate = successfulRunDate.ToLocalTime();
//and when displaying it convert to string with your format
string dateStr = field.LastRunDate.ToString("dd/MM/yyyy HH:mm");

if string

field.LastRunDate = successfulRunDate.ToLocalTime().ToString("dd/MM/yyyy HH:mm");

使用格式转换为LocTime
