Answer 1

To elaborate on Berry’s post:

enum Title
{
Mr =1,
Mrs,
Miss
}

An ENUM is a user-defined type. With the enumerator above, you can create as many instances of Title as you would like.

Title mine = Title.Mr; 
Title sister = Title.Miss;
etc.

An IEnumerable is an Array of enumerable types. Most helpful to me using the foreach statement.

IEnumerable<string> list = new[] {"stringone", "string2", "stringthree"};

foreach (string s in list)
{
    Console.WriteLine(s);  
}

will produce the following output:

stringone
string2
stringthree
