将WPF窗口投射到WPF UserControl

Question

Window and UserControl are similar in many aspect,

But Window can not be casted to UserControl simply by put "(Usercontrol) " before a window,

Window w = new Window();
Usercontrol u = (UserControl)w;  //not allowed

Is there other possible way can cast a Window to Usercontrol? (without modify the window's code)

Or it's impossible?

Answer 1

Window不会从UserControl继承，因此您将无法像这样投射它。
