无边框窗体的移动(winform/wpf)

WinForm
　　引入命名空间
　　using System.Runtime.InteropServices;

无边框移动
    [DllImport("user32.dll")]
    public static extern bool ReleaseCapture();
    [DllImport("user32.dll")]
    public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
    public const int WM_SYSCOMMAND = 0x0112;
    public const int SC_MOVE = 0xF010;
    public const int HTCAPTION = 0x0002;

    private void Form_MouseDown(object sender, MouseEventArgs e)
    {
      ReleaseCapture();
      SendMessage(this.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
    }

WPF
        private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
        {
            this.DragMove();
        }

上述的dragMove 如果实现不了的话，wpf可以使用以下的方式实现，
通过以上的方法也能过够实现
加入命名空间：
using System.Runtime.InteropServices;
using System.Windows.Interop;

namespace wintest
{
    
        [DllImport("User32.dll")]
        public static extern bool ReleaseCapture();
        [DllImport("User32.dll")]
        public static extern bool SendMessage(IntPtr hwnd, int wMsg, int wParam, int lParam);
        public const int WM_SYSCOMMAND = 0x0112;
        public const int SC_MOVE = 0xF010;
        public const int HTCAPTION = 0x0002;
    

        private void Window_MouseDown(object sender, MouseButtonEventArgs e)
        {
            ReleaseCapture();
            WindowInteropHelper wihHandle = new WindowInteropHelper(this);// 获得该window的句柄
            SendMessage(wihHandle.Handle, WM_SYSCOMMAND, SC_MOVE + HTCAPTION, 0);
        }
