C# unix时间生成错误

我试图生成一个unix时间戳，并且必须发送一个具有初始时间和响应时间的webrequest

我试过这个密码

long ticks = DateTime.UtcNow.Ticks - DateTime.Parse("01/01/1970 00:00:00").Ticks;
ticks /= 10000;
string timestamp = ticks.ToString() + "000000";
label1.Text = timestamp;
int k=0;
for (int i = 0; i < 100; i++)
{
   k = k + i;
}
long ticks2 = DateTime.UtcNow.Ticks - DateTime.Parse("01/01/1970 00:00:00").Ticks;
ticks2 /= 10000;
string timestamp2 = ticks.ToString() + "000000";
label2.Text = timestamp2;

---

错误是，两个标签框上的输出相同to

string timestamp2=ticks2.ToString（）+“000000”
太复杂了！只要这样做：

var unixTime = (dateTime - new DateTime(1970, 1, 1).ToLocalTime()).TotalSeconds + "000000";

var unixTime = (dateTime - new DateTime(1970, 1, 1).ToLocalTime()).TotalSeconds + "000000";
