عمل radius للفورم

السلام عليكم ورحمة الله وبركاته ،

وجد الحل ولكن هناك مشكلة بسيطة ارجو منكم افادتي

استخدمت هذا الكود

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, // height of ellipse
            int nHeightEllipse // width of ellipse
        );

        public Form1()
        {
            InitializeComponent();
            this.FormBorderStyle = FormBorderStyle.None;
            Region = System.Drawing.Region.FromHrgn(CreateRoundRectRgn(0, 0, Width, Height, 20, 20));
        }
    }
}

ولكن لاحظت ان الـ edges غير مستوية تشعر وكأنها مشرشرة .. غير جزابة .. هل هناك حل ؟؟

private void Form1_Paint(object sender, PaintEventArgs e)

{

//Form Property

this.FormBorderStyle = FormBorderStyle.None;

this.MaximizeBox = false;

this.MinimizeBox = false;

this.Width = 500;

this.Height = 500;

this.BackColor = Color.CadetBlue;

this.StartPosition = FormStartPosition.CenterScreen;

//Create round Edge Using GDI+.net

//using System.Drawing.Drawing2D;

int CornerRadius = 150;

GraphicsPath gp = new GraphicsPath();

gp.AddArc(0, 0, CornerRadius, CornerRadius, 180, 90);

gp.AddArc(0 +this.Width - CornerRadius, 0, CornerRadius, CornerRadius, 270, 90);

gp.AddArc(0 + this.Width - CornerRadius, 0 + this.Height - CornerRadius, CornerRadius, CornerRadius, 0, 90);

gp.AddArc(0, 0 + this.Height - CornerRadius, CornerRadius, CornerRadius, 90, 90);

this.Region = new Region(gp);

}

            gp.AddArc(0, 0 + this.Height - CornerRadius, CornerRadius, CornerRadius, 90, 90);
            this.Region = new Region(gp);
       
        }

شكراً اخي علي الرد

بعد تنفيذ الكود اصبح الفورم يختفي ويظهر بسرعة شديدة وكأنه يومض ..

استخدم نفس الكود فى الحدث Load  بدلا من Paint

        private void Form1_Load(object sender, EventArgs e)
        {
            //Form Property
            this.FormBorderStyle = FormBorderStyle.None;
            this.MaximizeBox = false;
            this.MinimizeBox = false;
            this.Width = 500;
            this.Height = 500;
            this.BackColor = Color.CadetBlue;
            this.StartPosition = FormStartPosition.CenterScreen;
            //Create round Edge Using GDI+.net
            //using System.Drawing.Drawing2D;
            int CornerRadius = 150;
            GraphicsPath gp = new GraphicsPath();
            gp.AddArc(0, 0, CornerRadius, CornerRadius, 180, 90);
            gp.AddArc(0 + this.Width - CornerRadius, 0, CornerRadius, CornerRadius, 270, 90);
            gp.AddArc(0 + this.Width - CornerRadius, 0 + this.Height - CornerRadius, CornerRadius, CornerRadius, 0, 90);
            gp.AddArc(0, 0 + this.Height - CornerRadius, CornerRadius, CornerRadius, 90, 90);
            this.Region = new Region(gp);
       
        }
