Foreach and custom objects

Question

Is it possible to print a property of a custom object in a foreach loop ?

The custom object is Person and has a property called Name.
I want to print all names of the persons in the personslist (PList)

This is the standard way of doing it. It is good, no doubt about that.

foreach (Person X in PList) //good one
{
Console.WriteLine(X.Name);
}

Some where I have seen that people used something like this.
If you know you are only interrested in the string Name, you could do it.

foreach (Person.Name Y in PList)
{
Console.WriteLine(Y);
}

foreach (var Z.Name in PList)
{
Console.WriteLine(Z);
}

Both the second and third foreach are not working for obvious reason.
It there a way to do it like that ?

Answer 1

From what I know there's no straightforward way like what you've shown, the nearest I can think of would be extracting the Name property via LINQ and iterate over the IEnumerable as follows:-

foreach (var name in PList.Select(p => p.Name))
{
// process name here
}

Hopefully it helps! 😉
