如何將Unix時間戳轉換爲DateTime，反之亦然？ - How can I convert a Unix timestamp to DateTime and vice versa?

問題：

There is this example code, but then it starts talking about millisecond / nanosecond problems. 有此示例代碼，但隨後開始談論毫秒/納秒問題。

The same question is on MSDN, Seconds since the Unix epoch in C# . 自M＃的Unix時代以來 ，一樣的問題在MSDN上，以秒爲單位 。

This is what I've got so far: 到目前爲止，這是我獲得的：

public Double CreatedEpoch
{
  get
  {
    DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime();
    TimeSpan span = (this.Created.ToLocalTime() - epoch);
    return span.TotalSeconds;
  }
  set
  {
    DateTime epoch = new DateTime(1970, 1, 1, 0, 0, 0, 0).ToLocalTime();
    this.Created = epoch.AddSeconds(value);
  }
}
