Converting unix time to DateTime
提问by tmighty
I would like to convert a Unix time stamp to a VB.NET DateTime.
我想将 Unix 时间戳转换为 VB.NET DateTime。
I have tried
我试过了
Public Function UnixToDateTime(ByVal strUnixTime As String) As DateTime
Dim nTimestamp As Double = strUnixTime
Dim nDateTime As System.DateTime = New System.DateTime(1970, 1, 1, 0, 0, 0, 0)
nDateTime.AddSeconds(nTimestamp)
Return nDateTime
End Function
But when I feed it
但是当我喂它的时候
strUnixTime = "1401093810"
I get the return value
我得到返回值
nDateTime = #1/1/1970#
What am I doing wrong? Thank you
我究竟做错了什么？谢谢

This line of code
这行代码
nDateTime.AddSeconds(nTimestamp)
does notmodify nDateTime. It's like writing a + 3on a line by it's own -- awon't be modified.
并没有改变nDateTime。这就像自己写a + 3在一行上一样——a不会被修改。
It does, however, return a new DateTime objectthat contains the incremented value. So, what you actually wanted to write is:
但是，它会返回一个包含递增值的新 DateTime 对象。所以，你真正想写的是：
nDateTime = nDateTime.AddSeconds(nTimestamp)
PS: It appears that your code does not use Option Strict On. It is strongly recommended that you activate Option Strictand use explicit instead of implicit conversions.
PS：您的代码似乎没有使用Option Strict On. 强烈建议您激活Option Strict并使用显式转换而不是隐式转换。
