推荐答案

我已经使用了这些代码并且确实有效

I have used these codes and it actually works

public const int WM_NCLBUTTONDOWN = 0xA1;
public const int HT_CAPTION = 0x2;

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

在你的表单鼠标按下事件中使用 ReleaseCapture 方法像这样

use the ReleaseCapture method in your form mouse down event Like this

if (e.Button == MouseButtons.Left)
            {
                ReleaseCapture();
                SendMessage(Handle, WM_NCLBUTTONDOWN, HT_CAPTION, 0);
            }
