如何使我的Windows窗体应用程序捕捉到屏幕边缘？

using System;
using System.Runtime.InteropServices;
using System.Windows.Forms;

public class FormWithBorderlessMaximize : Form
{
    private const int WM_NCHITTEST = 0x0084;
    private const int HTLEFT = 10;
    private const int HTRIGHT = 11;
    private const int HTTOP = 12;
    private const int HTTOPLEFT = 13;
    private const int HTTOPRIGHT = 14;
    private const int HTBOTTOM = 15;
    private const int HTBOTTOMLEFT = 16;
    private const int HTBOTTOMRIGHT = 17;
    private const int BORDER_WIDTH = 10;

    [DllImport("user32.dll")]
    public static extern int SendMessage(IntPtr hWnd, int Msg, int wParam, int lParam);

    [DllImport("user32.dll")]
    public static extern bool ReleaseCapture();

    protected override void WndProc(ref Message m)
    {
        const int WM_NCLBUTTONDOWN = 0x00A1;
        const int HT_CAPTION = 2;

        switch (m.Msg)
        {
            case WM_NCLBUTTONDOWN:
                if (m.WParam.ToInt32() == HT_CAPTION)
                {
                    ReleaseCapture();
                    SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0);
                }
                break;
        }

        base.WndProc(ref m);
    }

    public FormWithBorderlessMaximize()
    {
        this.FormBorderStyle = FormBorderStyle.None;
    }
}
