try this:
尝试这个：
using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form
{
[DllImport("Gdi32.dll", EntryPoint = "CreateRoundRectRgn")]
private static extern IntPtr CreateRoundRectRgn
(
int nLeftRect, // x-coordinate of upper-left corner
int nTopRect, // y-coordinate of upper-left corner
int nRightRect, // x-coordinate of lower-right corner
int nBottomRect, // y-coordinate of lower-right corner
int nWidthEllipse, // width of ellipse
int nHeightEllipse // height of ellipse
);
public Form1()
{
InitializeComponent();
this.FormBorderStyle = FormBorderStyle.None;
Region = System.Drawing.Region.FromHrgn(CreateRoundRectRgn(0, 0, Width, Height, 20, 20));
}
}
}
from here: Form with Rounded Borders in C#?
从这里开始：C# 中带有圆角边框的表单？
回答by Vinay Pratap Singh
The Region propery simply cuts off the corners. To have a true rounded corner you will have to draw the rounded rectangles.
Region 属性只是切断了角落。要获得真正的圆角，您必须绘制圆角矩形。
It might be easier to draw an image of the shape you want and put that on the transparent form. Easier to draw but cannot be resized.
绘制所需形状的图像并将其放在透明表单上可能更容易。更容易绘制但不能调整大小。

I found this code
我找到了这个代码
To come up with the rounded corners textbox, I started trying to work with the paint override event, but unfortunately without any result, which is due to the fact (I assume) that the textbox is derived from Windows. Therefore, I tried overriding the WM_PAINT API instead, which had the desired results
为了提出圆角文本框，我开始尝试使用绘制覆盖事件，但不幸的是没有任何结果，这是由于（我假设）文本框是从 Windows 派生的。因此，我尝试改写 WM_PAINT API，它得到了预期的结果
