Creating Static Properties
Like fields, properties can also be static, which means you don't need an object to use them. As an example, we'll convert the static field numberOfObjects in the static fields example (see Listing 3.7) into a property of the same name. That's easy enough—all we have to do is to implement the new property like this (note that the value of the property is stored in a private field, which must be static so we can access it from the static property):
public class CountedClass
{
private static int number = 0;
public CountedClass()
{
number++;
}
public static int NumberOfObjects
{
get
{
return number;
}
set
{
number = value;
}
}
}
Now we can use this new static property as we used the static field earlier, as you see in ch03_09.cs, Listing 3.9.
Listing 3.9 Creating a Static Property (ch03_09.cs)
class ch03_09
{
static void Main()
{
System.Console.WriteLine("Number of objects: {0}",
CountedClass.NumberOfObjects);
CountedClass object1 = new CountedClass();
System.Console.WriteLine("Number of objects: {0}",
CountedClass.NumberOfObjects);
CountedClass object2 = new CountedClass();
System.Console.WriteLine("Number of objects: {0}",
CountedClass.NumberOfObjects);
CountedClass object3 = new CountedClass();
System.Console.WriteLine("Number of objects: {0}",
CountedClass.NumberOfObjects);
}
}
public class CountedClass
{
private static int number = 0;
public CountedClass()
{
number++;
}
public static int NumberOfObjects
{
get
{
return number;
}
set
{
number = value;
}
}
}
