.net - Convert Point to Point^

Question

I'm trying move my form with using left mouse button. I have this:

if(e->Button == Windows::Forms::MouseButtons::Left)
{
    Point^ mousePos = gcnew Point();
    mousePos = Control::MousePosition;
        mousePos->Offset(mouse_offset->X,mouse_offset->Y);
    Location = mousePos;
}

Code seems ok, but Visual returning error:

error C2664: 'void System::Windows::Forms::Control::Location::set(System::Drawing::Point)' : cannot convert parameter 1 from 'System::Drawing::Point ^' to 'System::Drawing::Point'

I don't understand - I created variable mousePos as a Point^. Do you have any idea what's wrong?

Answer 1

Point 是一个值类（尽管不是不可变的）。为什么要在（托管）堆上分配一个？我在这个函数中没有看到任何证明这样做的理由。

Answer 2

问题是该方法需要一个Point，而您正在向它传递一个Point ^（托管指针Point- weeee，这里的“点”太多......）。
