推荐答案

您需要创建一个实现 WinForms IWin32Window 接口并返回 WPF 窗口句柄的类(使用 new WindowInteropHelper(window).Handle)，然后将其传递给表单的 ShowDialog.

You need to create a class that implements the WinForms IWin32Window interface and returns the WPF window's handle (using new WindowInteropHelper(window).Handle), then pass that to the form's ShowDialog.
