WPF没有提供任何功能来移除窗体上的icon图标。一般的做法是设置一个空白的图标,如下图1:
这种做法在窗体边框与标题之间仍然会保留一片空白。比较好的做法是使用Win32API提供的函数来移除这个图标。使用如下的代码:
public static class IconHelper { [DllImport("user32.dll")] static extern int GetWindowLong(IntPtr hwnd, int index); [DllImport("user32.dll")] static extern int SetWindowLong(IntPtr hwnd, int index, int newStyle); [DllImport("user32.dll")] static extern bool SetWindowPos(IntPtr hwnd, IntPtr hwndInsertAfter, int x, int y, int width, int height, uint flags); [DllImport("user32.dll")] static extern IntPtr SendMessage(IntPtr hwnd, uint msg, IntPtr wParam, IntPtr lParam); const int GWL_EXSTYLE = -20; const int WS_EX_DLGMODALFRAME = 0x0001; const int SWP_NOSIZE = 0x0001; const int SWP_NOMOVE = 0x0002; const int SWP_NOZORDER = 0x0004; const int SWP_FRAMECHANGED = 0x0020; const uint WM_SETICON = 0x0080; public static void RemoveIcon(Window window) { //获取窗体的句柄 IntPtr hwnd = new WindowInteropHelper(window).Handle; //改变窗体的样式 int extendedStyle = GetWindowLong(hwnd, GWL_EXSTYLE); SetWindowLong(hwnd, GWL_EXSTYLE, extendedStyle | WS_EX_DLGMODALFRAME); //更新窗口的非客户区,以反映变化 SetWindowPos(hwnd, IntPtr.Zero, 0, 0, 0, 0, SWP_NOMOVE | SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED); } }在窗体中只需重载OnSourceInitialized函数即可
protected override void OnSourceInitialized(EventArgs e) { IconHelper.RemoveIcon(this); }效果图:空白没有了。
