推荐答案

在WPF中这很容易做到 - 圆形玻璃WPF按钮的样式 [ ^ ]。如果您在互联网上搜索，您还可以找到更多信息。



Windows窗体将更具挑战性。它可以通过以下方式完成 - 绕过System.Windows的角落。 Forms.Control？ [ ^ ]。

This is very easy to do in WPF - A Style for Round Glassy WPF Buttons[^]. You will also find more information if you search on the internet.

Windows forms will be more challenging. It can be done though - Rounding the corners of System.Windows.Forms.Control?[^].

创建自己的继承类从文本框中应用代码...这样的事情 - >

Hi!
I know I'm a bit late, but for anyone who still needs it check -> this vid

Create your own class that inherits from Textbox and apply the code... something like this ->

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

class round :TextBox
    {
        [System.Runtime.InteropServices.DllImport("gdi32.dll", EntryPoint = "CreateRoundRectRgn")]
        private static extern IntPtr CreateRoundRectRgn
        (
            int nLeftRect, // X-coordinate of upper-left corner or padding at start
            int nTopRect,// Y-coordinate of upper-left corner or padding at the top of the textbox
            int nRightRect, // X-coordinate of lower-right corner or Width of the object
            int nBottomRect,// Y-coordinate of lower-right corner or Height of the object
            //RADIUS, how round do you want it to be?
            int nheightRect, //height of ellipse 
            int nweightRect //width of ellipse
        );
        protected override void OnCreateControl()
        {
            base.OnCreateControl(); 
             this.Region = System.Drawing.Region.FromHrgn(CreateRoundRectRgn(2,3,this.Width,this.Height,15,15)); //play with these values till you are happy
}

就是这样！

That's it!

覆盖按钮的绘制事件并自己绘制，也可以使用图像。

Override paint event of button and draw it yourself, you can use an image too.
