Hi,

What is the synatx in C# for calculating date difference between 2 dates in terms of no. of days?

Thanks,
Ben
 
Better yet, instead of using a VB function and since you're using C# try
this:

DateTime dt1 = <some date>;
DateTime dt2 = <some other date>;

TimeSpan ts = dt1 - dt2;

int days = ts.Days;

Why would someone use this for C#? Why not use the Compare method of the
DateTime structure?

Look up "DateTime.Subtract Method". You subtract one from another and get a
time span object:

TimeSpan ts = date1.Subtract(date2); // both are DateTime

NOTE: The suggestion of Compare() in answer to DateDiff (another answer
post) was a bit tongue in cheek. ;->

DateTime dt1 = new DateTime(....);
DateTime dt2 = new DateTime(...);

TimeSpan ts = dt1 - dt2;

or use

TimeSpan = DateTime.Now - dt1;

or whatever
 
I stand corrected with a big "Whoops!"

world.
