# Declaration

Let's declare a method which prints a message to the screen:

public static void PrintMessage()
{
    Console.WriteLine("Thank you");
}

Now, if we want to pass a specific message to print, we can pass it as an argument and we need to declare the message as a parameter:

public static void PrintMessage(string message)
{
    Console.WriteLine(message);
}

As you can see, we can have two methods named the same, but they differ through the parameter.

We call them like so:

PrintMessage();
PrintMessage("Understanding methods");

# Refactoring

To not repeat the logic inside methods, we can call one from another:

public static void PrintMessage()
{
    PrintMessage("Thank you");
}

public static void PrintMessage(string message)
{
    Console.WriteLine(message);
}
