What is best way to determine angle between two mappoints?
There are probably a number of approaches. I suggest using a LineBuilder to create a LineSegment using the two points as the start and the end point. The created segment in return contains an angle property.

this seems to work for me thanks for help
double Rad2Degrees = 180 / Math.PI;
var lineBuilder = new LineBuilder(p1, p2);
var lineSeg = lineBuilder.ToSegment();
var degrees = lineSeg.Angle * Rad2Degrees;
degrees = 90 - degrees;
if (degrees < 0)
degrees = degrees + 360;
so i think like the linesegment approach but it returns the angle relative to x axis going counter clockwise as opposed to the preferable gis coordinate system starting at y axis in a clockwise direction. so if the lineSegment.angle returns 30 degrees that would actually be 60 degrees on the compass. Is there a method or technique to make the conversion?
Alternatively, you may take a look at the Near Tool as well as the Generate Near Table Tool. Each allow you to generate the angle.
