Question

I have a little problem with windows forms in c#.
Let’s keep it simple: I have a method which sets the default background color and foreground color. I have multiple forms from which I want to call it and I want have only one method (keep the possibility to add a default background image, etc… ). How should I do it ?

This is the basic code:

public void LoadGraphics() {
  this.BackColor = Graphics.GraphicsSettings.Default.BackgroundColor;
  this.ForeColor = Graphics.GraphicsSettings.Default.ForegroundColor;
  this.BackgroundImage = new Bitmap(Graphics.GraphicsResources.bg_small);
}

Answer 1

Create a parent class that implements the method and derive your Forms from that parent class:

class Foo : Form {
    void LoadGraphics() {
        this.BackColor = Graphics.GraphicsSettings.Default.BackgroundColor;
        this.ForeColor = Graphics.GraphicsSettings.Default.ForegroundColor;
        this.BackgroundImage = new Bitmap(Graphics.GraphicsResources.bg_small);
    }
}

class YourForm : Foo {
    void someFunction() {
        LoadGraphics();
    }
}
