Question

I have a object which it was initialized before in a base class. In inherited class, I use this object and assign values on multi-properties to it. Example:

this.Chart.X = 10;
this.Chart.Y = 10;
this.Chart.Width = 20;
this.Chart.Height = 20;
this.Chart.Background = Color.Red;

However, I must repeat “this.Chart” many times. How to avoid this. Note that I don’t want to re-create this object again because in the base class, it was initialized with some common values.

Thanks.

You could make a set of extension methods for Chart that implement a fluent interface. It will get rid of some of the repeated code, so your example could looks something like:

this.Chart.X(10).Y(10).Width(20).Height(20).Background(Color.Red);

And you don’t even need this.
