c构造函数的尖锐等价物

Question

Not sure if my title is correct. Forgot what it is code. But here i will explain it through code.

you see in java you can declare a class like this.

class Panel extends View{

        public Bitmap mBitmap;

        public Panel(Context context) {
            super(context);

        }

}

in c sharp

  class Panel : View
    {

        public Panel(Context context){
            base(context);
        }

    }

it has an error. how do you declare a class constructor like that in csharp?

Answer 1

class Panel : View
{
    public Panel(Context context) : base(context)
    {
    }
}

Answer 2

In C#, calling the base constructor is a bit more explicit (or rather explicitly separate)

While in Java it would look like just any statement that could be reordered with the other statements in the body, it's moved outside the normal constructor body in C#.

class Panel : View
{
    public Panel(Context context) : base(context) { }
}
