Question

.net字符串转换为时间戳函数

Answer 1

转自：C# 和 Linux 时间戳转换
/// <summary>
/// 时间戳转为C#格式时间
/// </summary>
/// <param name=”timeStamp”></param>
/// <returns></returns>
private DateTime GetTime(string timeStamp)
{
DateTime dtStart = TimeZone.CurrentTimeZone.ToLocalTime(new DateTime(1970, 1, 1));
long lTime = long.Parse(timeStamp + "0000000");
TimeSpan toNow = new TimeSpan(lTime); return dtStart.Add(toNow);
}

/// <summary>
/// DateTime时间格式转换为Unix时间戳格式
/// </summary>
/// <param name=”time”></param>
/// <returns></returns>
private int ConvertDateTimeInt(System.DateTime time)
{
System.DateTime startTime = TimeZone.CurrentTimeZone.ToLocalTime(new System.DateTime(1970, 1, 1));
return (int)(time - startTime).TotalSeconds;
}

Answer 2

应该没有转门的函数来获取时间戳，不过可以这样来获得：

TimeSpan toNow = DateTime.Now.Subtract(new DateTime(1970, 1, 1));
MessageBox.Show(toNow.TotalMilliseconds.ToString());
