C# Properties Question

[Wnt2bsleepin]

Hello, I am an intermediate Java programmer and I have some questions about Properties that I cannot find anywhere. From what I gather, they are similar to Java's getter and setter methods, but seem like they may be more powerful.

private string color; 

public string Color
{
    get 
    {
        return color.ToUpper(); 
    }
    set 
    { 
        if(value == "Red")
            color = value; 
        else
            Console.WriteLine("This car can only be red!");
    }
}

This allows you to set the private string color to any string. I am just curious about how you would call such a method? How you differentiate between setting and getting when you make the call. Where is the variable "value" coming from?

Just some things that I would like to clarify before I move on. Thank you for any help.
