System.Drawing.Point运算符错误

Question

可能重复:
如何在向两个点添加两个点的同时使+运算符工作？

我的代码

position.Location = (e.Location + pic1.Location) - bild_posi.Location;

错误如:

the operator "+" isnt compatible with "System.Drawing.Point + System.Drawing.Point"

我怎样才能解决这个问题？

Answer 1

它取决于您希望如何将点添加到一起

您可以编写一个名为AddPoints的方法和一个名为SubtractPoints的方法,例如

private Point AddPoints(Point A, Point B)
{
    return new Point(A.X + B.X, A.Y + B.Y);
}

private Point SubtractPoints(Point A, Point B)
{
    return new Point(A.X - B.X, A.Y - B.Y);
}

然后像使用它一样

position.Location = SubtractPoints(AddPoints(e.Location,pic1.Location),bild_posi.Location);
