C#的get和set

初学初学C#，发现跟Java没啥区别:)

//Class
public class TestClass
{
private double _numberA = 0;
public double NubmerA
{
get { return _numberA;}
set { _numberA = value;}
}
}
//Main
public class MainClass
{
public static void Main()
{
TestClass t = new TestClass();
r.NumberA = 123.456; // Derived class property
Console.WriteLine("Number in the derived class is " + d1.NumberA);
}
}
