提问by AltF4_
I have a bunch of numbers which I get which are like 1.567or 22.654or 220.123and I want to convert them to time in the 00:00:00.000 (hours/Minutes/Seconds.Miliseconds)
我有一堆数字，它们是像1.567或22.654或这样的220.123，我想将它们转换为时间00:00:00.000 (hours/Minutes/Seconds.Miliseconds)

Use DateTime.AddHoursmethod. It takes doublevalues as a parameter:
使用DateTime.AddHours方法。它以double值作为参数：
Dim d as DateTime = (new DateTime()).AddHours(1.567)
Result is {0001-01-01 01:34:01}
结果是 {0001-01-01 01:34:01}
Then you can use DateTime.ToString()method to get time in desired format:
然后您可以使用DateTime.ToString()方法以所需格式获取时间：
Dim s as String = d.ToString("HH:mm:ss.fff")
Results is "01:34:01.200"
结果是 "01:34:01.200"
It will work for all values from 0to 23.99
它将适用于从0到的所有值23.99

If your input values represents hours and they can be greater then 24 you can use TimeSpaninstead of DateTime:
如果你的输入值代表小时，他们可以大于24就可以使用TimeSpan，而不是DateTime：
Dim d as TimeSpan = TimeSpan.FromHours(220.123)
Dim s As String = string.Format("{0}:{1}:{2}.{3}", CInt(d.TotalHours), d.Minutes, d.Seconds, d.Milliseconds)
