Question

I’m having some trouble here.
Did some research on Google but I can’t seem to find what I’m looking for.
I’m trying to ask for two inputs (datetimes) in hh:mm format, subtract one for the other then return the result of that value in minutes.
The problem is that I want to return that value as an integer and I can’t seem to find the right way to do it.
In C/C++ I wouldn’t have this kind of issues…
Anyways, here’s a snippet of what I’m talking about.

private int DuraçaoTreino(DateTime dtInicioTreino, DateTime dtFimTreino, int dtDuraçao)
{
    Console.WriteLine("Introduza a hora de inicio (hh:mm): ");
    dtInicioTreino = Convert.ToDateTime(Console.Read());
    Console.WriteLine("Introduza a hora de fim (hh:mm): ");
    dtFimTreino = Convert.ToDateTime(Console.Read());
    dtDuraçao = (dtFimTreino - dtInicioTreino); // duração da sessão de treino
    dtDuraçao = Convert.ToDecimal(Console.Read());
    return dtDuraçao;                  
} 

And that’s pretty much it… I’m new to C# so if you see anything wrong please be kind.

Thanks in advance.

What you’re talking about is a TimeSpan:

DateTime dtBegin   = new DateTime(2011,5,1,22,0,0) ; // 10pm 1 May 2011
DateTime dtEnd     = new DateTime(2011,5,1,23,0,0) ; // 11pm 1 May 2011
TimeSpan tmElapsed = dtEnd - dtBegin ;               // tmElapsed is a TimeSpan with a value of 60 minutes

To return the minutes, do something like:

int elapsedTimeInMinutes = (int) Math.Round( tmElapsed.TotalMinutes , 0 ,MidpointRounding.ToEven ) ;
