Static Method -- Is it usual behavior?

Have a small doubt with static method.

Documentation says that "Static method can't access instance member variable OR static methods and properties can only access static fields and stat开发者_开发百科ic events since it's gets executed much before an instance is created". So, the below code fails to compile

class staticclass
{
    int a = 20; //Private member

    public static void staticmethod()
    {
        Console.WriteLine("Value Of Instance member variable is: {0}",a);  // Error
    }

}

But we also know that, inside a static method we can create an instance of the same class.

So, changing the above code a bit I can access the instance variable in static method

class staticclass
{
    int a = 20; //PRivate Memeber

    public static void staticmethod()
    {
        staticclass sc = new staticclass(); 
        Console.WriteLine("Value Of Instance member variable is: {0}",sc.a);  
    }

}

This Compiles fine and displays the result Value Of Instance member variable is: 20.

Is this a normal behavior? OR I am not able to understand it correctly?

I mean, if this the case then How the statements holds true static methods can only access static fields?

Thanks.

You're misunderstanding what static means – it means that you only have access to static members of this. It doesn't restrict you accessing another object's non-static members.

The fact that the "other" object you're accessing in your static method happens to be an instance of the same class does not matter.
