1、窗体边角圆弧处理
在窗体的Paint事件中或者Resize事件中处理这个过程,具体代码如下:
private void SetFormCircle()
{
int radian = 4; //圆弧角的比率,可以自己改变这个值看具体的效果
int w = this.Width; //窗体宽
int h = this.Height; //窗体高
//对于矩形的窗体,要在一个角上画个弧度至少需要2个点,所以4个角需要至少8个点
Point p1 = new Point(radian, 0);
Point p2 = new Point(w - radian, 0);
Point p3 = new Point(w, radian);
Point p4 = new Point(w, h - radian);
Point p5 = new Point(w - radian, h);
Point p6 = new Point(radian, h);
Point p7 = new Point(0, h - radian);
Point p8 = new Point(0, radian);
System.Drawing.Drawing2D.GraphicsPath shape = new System.Drawing.Drawing2D.GraphicsPath();
Point[] p = new Point[] { p1, p2, p3, p4, p5, p6, p7, p8 };
shape.AddPolygon(p);
//将窗体的显示区域设为GraphicsPath的实例
this.Region = new System.Drawing.Region(shape);
}
2、c#中调用外部程序
比如要打开一“c:\windows”这个目录,可以这些做
Process.Start("explorer.exe",@"c:\windows");
要执行一个DOS批处理,可以这样做
//sPath是批处理文件的路径
myProcess.StartInfo.FileName = sPath;
myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
myProcess.StartInfo.Verb = "open";
myProcess.StartInfo.CreateNoWindow = false;
myProcess.StartInfo.UseShellExecute = false;
myProcess.Start();
