point in c#

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 what is the change I should to do ?

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;

I am not sure what you are trying to do, but if you need to use angleOf method, you need to create 2 points, such as :
Point pt1 = new Point(100, 100);
Point pt2 = new Point(200, 200);
angle = angleOf(pt1, pt2);
textBox1.Text += angle;

This will build and write a number on textbox, but I don't know if that's the number you want..

angleOf method takes Point as a parameter.
angle = angleOf(xy.X, xy.Y) // in this line you are sending int, that's what the error message says.

ok,if I use like this
Point xy = new Point(4444,2222);
angle = angleOf(xy.X, xy.Y);
I have this error
1-
Error 1 The best overloaded method match for 'angle.Form1.angleOf(System.Drawing.Point, System.Drawing.Point)' has some invalid arguments
2-
Error 2 Argument 1: cannot convert from 'int' to 'System.Drawing.Point'
3-
Error 3 Argument 2: cannot convert from 'int' to 'System.Drawing.Point

Point pt1 = 4428900.38515348; // this line of code will not build successfully
You can create point this way with x and y coordinates.
Point pt1 = new Point(100,100) // x, y coordinates.

meena moon,
What do you mean by "prototype" here?

My problem is
Point pt1 = 4428900.38515348;
Point pt2 = 4428900.38515346;
Ican't set this number to this virables because the prototype of pt1 and pt2

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