C#:绘制Winform窗体

Winform窗体缺少左上角效果:

 public void SetWindowRegion()
{
System.Drawing.Drawing2D.GraphicsPath FormPath;
FormPath = new System.Drawing.Drawing2D.GraphicsPath();
Rectangle rect = new Rectangle(, , this.Width, this.Height);
int diameter = ;
FormPath .AddRectangle(new Rectangle(rect.Location.X + diameter, rect.Location.Y, rect.Width - diameter, rect.Height));
FormPath .AddRectangle(new Rectangle(rect.Location.X, rect.Location.Y + diameter, diameter, rect.Height - diameter));
path.CloseFigure(); this.Region = new Region(FormPath); } protected override void OnResize(System.EventArgs e)
{ this.Region = null; SetWindowRegion(); }

参考:Winform窗体四圆角效果:

public void SetWindowRegion()

{

    System.Drawing.Drawing2D.GraphicsPath FormPath;

    FormPath = new System.Drawing.Drawing2D.GraphicsPath();

    Rectangle rect = new Rectangle(, , this.Width, this.Height - );//this.Left-10,this.Top-10,this.Width-10,this.Height-10);                 

    FormPath = GetRoundedRectPath(rect, );

    this.Region = new Region(FormPath);

}

private GraphicsPath GetRoundedRectPath(Rectangle rect, int radius)

{

    int diameter = radius;

    Rectangle arcRect = new Rectangle(rect.Location, new Size(diameter, diameter));

    GraphicsPath path = new GraphicsPath();

    //   左上角   

    path.AddArc(arcRect, , );

    //   右上角   

    arcRect.X = rect.Right - diameter;

    path.AddArc(arcRect, , );

    //   右下角   

    arcRect.Y = rect.Bottom - diameter;

    path.AddArc(arcRect, , );

    //   左下角   

    arcRect.X = rect.Left;

    path.AddArc(arcRect, , );

    path.CloseFigure();

    return path;

}

protected override void OnResize(System.EventArgs e)

{

    this.Region = null;

    SetWindowRegion();

}
