用格式转换toLocalTime

Question

我有一个DateTime.Utcnow，我想转换成本地时间。我想把它转换成"dd/MM/yyyy HH:mm"格式的本地时间。ToLocalTime没有构造函数。

_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

如属字符串

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

在DateTime的情况下

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？根据类型的不同，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字符串

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