我如何将这些合并为 1 个函数

Question

Trying to code clean; the goal is to create rounded .Net objects.
I would prefer to have 1 call regardless of object type as I figure this will get out of hand quickly.

region BuildOvals

    //object fails as parameter Width/Height unavailable - there is likely a good way to merge these three void function 1 call but I "can't be asked" - Remo 2019

    public void buildOval(int oWDelta, int oHDelta, PictureBox o)
    {
        System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath();
        gp.AddEllipse(0, 0, o.Width - oWDelta, o.Height - oHDelta);
        Region rg = new Region(gp);
        o.Region = rg;
    }
    public void buildOval(int oWDelta, int oHDelta)
    {
        System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath();
        gp.AddEllipse(0, 0, this.Width - oWDelta, this.Height - oHDelta);
        Region rg = new Region(gp);
        this.Region = rg;
    }
    public void buildOval(int oWDelta, int oHDelta, Button o)
    {
        System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath();
        gp.AddEllipse(0, 0, o.Width - oWDelta, o.Height - oHDelta);
        Region rg = new Region(gp);
        o.Region = rg;
    }
    #endregion

You could the following. From your code, it looks like the parameter o is a Control. For example

public void buildOval(int oWDelta, int oHDelta, Control o)
{
    using (System.Drawing.Drawing2D.GraphicsPath gp = new System.Drawing.Drawing2D.GraphicsPath())
    {
       gp.AddEllipse(0, 0, o.Width - oWDelta, o.Height - oHDelta);
       Region rg = new Region(gp);
       o.Region = rg;
    }
}

You could now call them the methods as

 buildOval(wDeltaValue,oDeltaValue,this); // when called for Form
 buildOval(wDeltaValue,oDeltaValue,pictureBoxInstance);
 buildOval(wDeltaValue,oDeltaValue,buttonInstance);
