Calculating time between two dates?

Question

Can someone please help me to make this work?

I want to calculate the time between two dates in VB.NET like this:

startdate: 2011/12/30  
enddate: 2011/12/31  

Calculate: ? hour ? minute ? seconds

Answer 1

You Can try this

DateTime startTime = DateTime.Now;

DateTime endTime = DateTime.Now.AddSeconds( 75 );

TimeSpan span = endTime.Subtract ( startTime );
Console.WriteLine( "Time Difference (seconds): " + span.Seconds );
Console.WriteLine( "Time Difference (minutes): " + span.Minutes );
Console.WriteLine( "Time Difference (hours): " + span.Hours );
Console.WriteLine( "Time Difference (days): " + span.Days );

Output Like,

Time Difference (seconds): 15
Time Difference (minutes): 1
Time Difference (hours): 0
Time Difference (days): 0

And the VB.Net equivalent to the above:

Dim startTime As DateTime = DateTime.Now

Dim endTime As DateTime = DateTime.Now.AddSeconds(75)

Dim span As TimeSpan = endTime.Subtract(startTime)
Console.WriteLine("Time Difference (seconds): " + span.Seconds)
Console.WriteLine("Time Difference (minutes): " + span.Minutes)
Console.WriteLine("Time Difference (hours): " + span.Hours)
Console.WriteLine("Time Difference (days): " + span.Days)

When you subtract 2 DateTimes, you get a TimeSpan struct that has all of those properties for you.
