可以使用的Win32 API是:
[DllImport("user32.dll")] private extern static bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter, int X, int Y, int cx, int cy, int uFlags);
static void SetWindowPosition(string locationURL) { SHDocVw.ShellWindows windows = new SHDocVw.ShellWindows(); SHDocVw.InternetExplorer currentWindow = null; foreach (SHDocVw.InternetExplorer window in windows) { if (window.LocationURL.Contains(locationURL)) { currentWindow = window; break; } } if (currentWindow != null) { IntPtr handle = (IntPtr)currentWindow.HWND; var width = Screen.PrimaryScreen.Bounds.Width; var height = Screen.PrimaryScreen.Bounds.Height; SetWindowPos(handle, (IntPtr)0, width / 2, 0, width / 2, height, 0x0040); } }
