我有一个带有多个功能区的 Excel 插件,一个功能区是设置窗口。单击它时,将显示一个自定义窗口。但是,单击时不会显示任何内容。我在日志文件中看到以下异常。是什么原因造成的,如何解决?非常感谢

点击ribbon时,执行代码,ConnectionSetup就是上面的xaml文件
private bool GetSettings()
{
var settingUI = new ConnectionSetup();
settingUI.DataContext = Settings;
CenterMainWindow(settingUI, wndHandle.Handle);
bool? result = settingUI.ShowDialog();
return result ?? false;
}
private void CenterMainWindow(System.Windows.Window window, IntPtr ownerHandle)
{
var helper = new System.Windows.Interop.WindowInteropHelper(window) {Owner = ownerHandle};
// Center window
// Note - Need to use HwndSource to get handle to WPF owned window,
// and the handle only exists when SourceInitialized has been
// raised
window.SourceInitialized += delegate
{
// Get WPF size and location for non-WPF owner window
var nonWPFOwnerLeft = XLApp.Left;
var nonWPFOwnerWidth = XLApp.Width;
var nonWPFOwnerTop = XLApp.Top;
var nonWPFOwnerHeight = XLApp.Height;
// Get transform matrix to transform non-WPF owner window
// size and location units into device-independent WPF
// size and location units
var source = System.Windows.Interop.HwndSource.FromHwnd(helper.Handle);
if (source != null && source.CompositionTarget != null)
{
var matrix = source.CompositionTarget.TransformFromDevice;
var ownerWPFSize =
matrix.Transform(new System.Windows.Point(nonWPFOwnerWidth,
nonWPFOwnerHeight));
var ownerWPFPosition =
matrix.Transform(new System.Windows.Point(nonWPFOwnerLeft,
nonWPFOwnerTop));
// Center WPF window
window.WindowStartupLocation = WindowStartupLocation.Manual;
window.Left = Math.Max(0,
ownerWPFPosition.X +
(ownerWPFSize.X - window.Width)/2);
window.Top = Math.Max(0,
ownerWPFPosition.Y +
(ownerWPFSize.Y - window.Height)/2);
}
};
}
