I had a situation where I needed to determine how many objects in a generic list were missing a value in a property. That count was very important to the user. Basically, I was looking for all the objects in the list that didn't have a value in the path property. Normally, I would have created a count integer and a loop of some sort and just counted.
int count = 0;
foreach(Profile p in Profiles)
{
if(String.IsNullOrEmpty(p.Path))
{
count++;
}
}
I could have also used an anonymous delegate, but I was playing with Linq and found this little short cut.
int count = (from p in profiles where String.IsNullOrEmpty(p.Path) select p).Count();
I think that this is much cleaner and easier to read. Happy Linq'n!
