什么是正确的算法来计算一个WPF线角的度数？

What is the "correct" algorithm to calculate the angle in degrees from a WPF Line?

推荐答案

您需要的 ATAN2 。然而，这将让你在弧度的角度，转换成度必须是易于:-)角度的计算公式为 ATAN2（Y2 - Y1，X2 - X1），其中（X1，Y1）和（x2，y2）是你的行结束。

You need atan2. This would however give you the angle in radians, converting to degrees must be easy :-) The angle is calculated as atan2(y2 - y1, x2 - x1), where (x1, y1) and (x2, y2) are your line ends.

请注意，该常数 PI 是的可用了。

Note that the constant pi is available, too.
