推荐答案

好的，没问题，你可以给一个控制其Region属性的任意形状。添加一个新类到您的项目并粘贴如下所示的code。编译。从工具箱的上方新的控制到您的表单。

Yes, no problem, you can give a control an arbitrary shape with its Region property. Add a new class to your project and paste the code shown below. Compile. Drop the new control from the top of the toolbox onto your form.

using System;
using System.Drawing;
using System.Drawing.Drawing2D;
using System.Windows.Forms;

class OvalPictureBox : PictureBox {
    public OvalPictureBox() {
        this.BackColor = Color.DarkGray;
    }
    protected override void OnResize(EventArgs e) {
        base.OnResize(e);
        using (var gp = new GraphicsPath()) {
            gp.AddEllipse(new Rectangle(0, 0, this.Width-1, this.Height-1));
            this.Region = new Region(gp);
        }
    }
}
