Calculate minutes between two 24-hour time values 1

[heseir]

Hallo,

In VB6 i used this function:
Function TimeDiff(ByVal inTime As String, ByVal outTime As String)
Dim ainTime As Date, aoutTime As Date
Dim mElapsed As Long

ainTime = Format(Right("0" & inTime, 4), "@@@") ' right justify the inTime
aoutTime = Format(Right("0" & outTime, 4), "@@@") ' right justify the outTime

TimeDiff = DateDiff("n", ainTime, aoutTime) ' calculate number of minutes elapsed
End Function

I can not seem to find any similar function in C#.

Is there any genies out there who can magically transform this one into a C# function.

The format I get from my users are ex. "0735" (began at work), and I then need to calculate minutes passed since "0000" (midnight"). In VB6 I then called TimeDiff(0000, 0735), and got 455, which is minutes between the two times.

All help and pointers will be greatly appreaciated!

double TimeDiff(string start, string end)
{

DateTime startTime = DateTime.Parse(DateTime.MinValue.ToShortDateString() + " " + int.Parse(start).ToString("00:00"));
DateTime endTime = DateTime.Parse(DateTime.MinValue.ToShortDateString() + " " + int.Parse(end).ToString("00:00"));

TimeSpan ts;
ts = endTime- startTime ;




return ts.TotalMinutes;


}
