Question

iam using c# and have a question,how the static field is used to count the number of instances in a class,please calrify in terms of memory,thanks in advance.

Answer 1

Simply add a counter to the constructor of your class

class MyClass
{

    static int instanceCount = 0;

    public MyClass()
    {
        instanceCount++;
    }

}

The constructor runs every time an instance of the class is created. The static variable is shared by all instances of the created class.
