WINFORM不规则形状的按钮怎么做

Answer 1

使用Region属性和System.Drawing.Drawing2D.GraphicsPath类

private void button1_Paint(object sender, PaintEventArgs e)
{
System.Drawing.Drawing2D.GraphicsPath myg = new System.Drawing.Drawing2D.GraphicsPath();

//myg.AddEllipse(new Rectangle(0, 0, 100, 80)); //加椭圆
//button1.BackColor = Color.Purple;
//button1.Size = new System.Drawing.Size(256, 256);
//button1.Region = new Region(myg);

FontFamily ff = new FontFamily("Arial");
string str = "Click Me!";
int fs = (int)FontStyle.Bold;
int emsize = 35;
PointF origin = new PointF(0, 0);
StringFormat sf = new StringFormat(StringFormat.GenericDefault);
myg.AddString(str, ff, fs, emsize, origin, sf);
button1.Region = new Region(myg);
}

画图片上去，定义好按钮坐标，捕捉鼠标位置、按键等，自己来实现按钮功能即可
