Question

在我的wpf应用程序中发生了一些奇怪的事情，我有一个主窗口，其中包含一些用户可以在它们之间导航的页面。该应用程序在我的Windows 10操作系统上运行良好，但是当我在Windows服务器2012上运行时，如果我正在玩窗口大小的应用程序崩溃。

这里是主窗口xaml：

看起来您需要在Window代码中处理窗口大小调整。当我用窗口制作任何东西（调整大小，移动）时，这段代码对我有用

    public Window1()
{
     InitializeComponent();

      this.SourceInitialized += Window1_SourceInitialized;
}

private void Window1_SourceInitialized(object sender, EventArgs e)
{
    WindowInteropHelper helper = new WindowInteropHelper(this);
    HwndSource source = HwndSource.FromHwnd(helper.Handle);
    source.AddHook(WndProc);
}

const int WM_SYSCOMMAND = 0x0112;
const int SC_MOVE = 0xF010;
const int WM_WINDOWPOSCHANGED = 0x0047;
const int WM_WINDOWPOSCHANGING = 0x0046;
const int WM_EXITSIZEMOVE = 0x0232;

private IntPtr WndProc(IntPtr hwnd, int msg, IntPtr wParam, IntPtr lParam, ref bool handled)
{

    switch (msg)
    {
        case WM_SYSCOMMAND:
                int command = wParam.ToInt32() & 0xfff0;
                if (command == SC_MOVE && command == WM_WINDOWPOSCHANGED &&
                    command == WM_WINDOWPOSCHANGING && command == WM_EXITSIZEMOVE)
                    {
                        handled = true;
                    }
                break;
            default:
                break;
        }
        return IntPtr.Zero;
    }
