<csharp> List<int> scores = new List<int>(); //A list of ints

List<string> names = new List<string>(); //A list of strings

//add some ints to the scores list scores.Add(100); scores.Add(7);

//Add some names to the names list names.Add("Jeff"); names.Add("Uncle Eddie");

foreach(string name in names) {

  Console.WriteLine(name);

}

</csharp>

Simple arrays and multidimensional arrays

OOP Arrays

In class demo coins
Quarter class
*Mint

Functions/Methods

Function help with code reuse. If your going to use it more than once make it into a funtions. syntax simple

[access-modifier] return type indentifier ( [parateters] )
{
    //some code
}

access-modifiers
public : mean that this method can be called from anywhere else in the program

}

public static string HelloToName (string Name) {

   return "Hello " + Name;

}</csharp>

Calling a finction in c#

<csharp>string firstHello, jeffHello; //declare some strings firstHello = Hello(); //call the function Hello jeffHello = HelloToName("Jeff"); //call the function HelloToName </csharp>

Console Example /infod/jeff/classSource/class3/function.cs - source

Hello World!
Hello
Hello Jeff
Hello Marge
