I have this code ,I want to send pt1 and pt2 when click on button to method I have problem in prototype of pt1 and pt2
My problem is
Point pt1 = 4428900.38515348;
Point pt2 = 4428900.38515346;
Ican't set this number(double num) to this virables because the prototype of pt1 and pt2 and I want this virables have prototype Point
what is the change I should to do ?

What I have tried:

public double angleOf(Point p1, Point p2)
    double deltaY = (p2.Y - p1.Y);
    double deltaX = (p2.X - p1.X);
    double result = Math.Atan2(deltaY, deltaX);
    result *= (180 / Math.PI);
    result += 22.5;
    return (result < 0) ? (360d + result) : result;

private void button1_Click(object sender, EventArgs e)
    double angle;

    Point pt1 = 4428900.38515348;

    Point pt2 = 4428900.38515346;
    angle = angleOf(pt1, pt2);
    textBox1.Text += angle;

Point p1 = new Point(1,2);

I don't have (num,num) I have pt1=onenumber

Then you don't have a point with an X and Y value do you? So set the x or y accordingly: p1.X = 12.2233 etc.

sorry,Idont anderstand you :)

How about using PointD instead?
_Tuba 12-Feb-16 13:29pm
we have PointF I dont find PointD

Could you convert your doubles to floats (and vice versa)? or make your own PointD class see "".

1 solution

The standard .NET Point struct represents a point on a flat plane with an X and Y coordinate, held as integer values - there is the PointF struct, which represents the same plane, but uses floating point values instead of integers.
Neither of these are designed to hold a point on a line rather than on a plane (ie, a single number value) - so if you want to do such, you need to create your own class (or struct) and provide methods to work with them - such as AngleOf - but we can't do that for you, and you can't really "hack about" with the existing Point or PointF class to do that because all you will do is make your code hard to understand and maintain.

Do you really think the OP wishes to compute the angle betweeen two points in the same line? :-)
OriginalGriff 12-Feb-16 15:29pm
No, but he doesn't really give enough info to assume anything else, particularly if you look at his angle of method, which assumes that his two points have an x and y component.
Probably, the aaaa.bbbb number is actually an xxxx.yyyy value, but it's difficult to be sure - it looks like he's copying code from different parts of the internet and assuming that they will all automatically with together if he can get it to compile... :sigh:
