SegmentType Enumeration
In This Topic
Describes the type of line segment. See the Segment.SegmentType property.
Syntax
`public enum SegmentType : System.Enum, System.IComparable, System.IConvertible, System.IFormattable  `
```Public Enum SegmentType
Inherits System.Enum
Implements System.IComparable, System.IConvertible, System.IFormattable ```
Members
MemberDescription
Bezier A third degree cubic Bezier curve. A non-linear segment defined by four control points. The Bezier curve starts at control point 0 (start point) and ends at control point 3 (end point) The start point and control point 1 define the tangent at the start point. Control point 2 and the end point define the tangent at the end point. The length of these tangent lines and position of the 4 control points determines the shape of the created Bezier curve.
EllipticArc An elliptic arc is the portion of the boundary of a 2D ellipse that connects two points.
Line A straight line segment between a start point and end point.
Example
Enumerate the parts of a Polyline
```ReadOnlyPartCollection polylineParts = polyline.Parts;

// enumerate the segments to get the length
double len = 0;
while (segments.MoveNext())
{
foreach (Segment s in seg)
{
len += s.Length;

// perhaps do something specific per segment type
switch (s.SegmentType)
{
case SegmentType.Line:
break;
case SegmentType.Bezier:
break;
case SegmentType.EllipticArc:
break;
}
}
}

// or use foreach pattern
foreach (var part in polyline.Parts)
{
foreach (var segment in part)
{
len += segment.Length;

// perhaps do something specific per segment type
switch (segment.SegmentType)
{
case SegmentType.Line:
break;
case SegmentType.Bezier:
break;
case SegmentType.EllipticArc:
break;
}
}
}```
