iterate Through Class Fields

[Tealc]

I have some classes with a lot of fields I need to check. Its takes so much duplicated code to check each field so I want to iterate through each field.

How can I do it? It doesn't compile.

public class Person
{
// all fields are required
private string firstName;
private string middleName;
private string lastName;

public bool IsValid()
{
foreach(string str in this)
{
if (str == string.Empty)
{
return false;
}
}
return true;
}

It should check first middle and last name fields and return false if any are empty. But it doesn't compile.

What is the correct syntax?

Thanks.
