Need help writing this piece of logic...

Address is a value object in my code. It has a set of variables with get;set;
I get list of Address and I need to iterate the list, get the variables out of the first object in the list and put in a string(var1+var2+...).. As a final output I need a concatenated string of string[0] + string [1] ....string[i] (i being the size of the list)..

For ex: my address object is

public Address() {
public string street {get;set;}
public string city{get;set;}
}

I have a list of address Address[] addList = new List<Address>(); the size of the list is 3 in this example

Need to iterate the list and get object out of it.

for(Address a :addList) {
String first object txt = a0.street+a0.city;
String second object txt = a1.street+a1.city;
String third object txt = a2.street+a2.city;
}

String finaltxt = first object txt + second object txt + third object txt.

Please help!
