LineSegment Class
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Represents a line drawn between two points, which can be part of a PathFigure within Path data.

Methods
Name | Description | |
---|---|---|
CheckAccess | Determines whether the calling thread has access to this object. (Inherited from DependencyObject.) | |
ClearValue | Clears the local value of a dependency property. (Inherited from DependencyObject.) | |
Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) | |
Finalize | Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) | |
GetAnimationBaseValue | Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.) | |
GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) | |
GetType | Gets the Type of the current instance. (Inherited from Object.) | |
GetValue | Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.) | |
MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) | |
ReadLocalValue | Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.) | |
SetValue | Sets the local value of a dependency property on a DependencyObject. (Inherited from DependencyObject.) | |
ToString | Returns a string that represents the current object. (Inherited from Object.) |

Remarks
Use a PathFigure object to create composite shapes using LineSegment objects and other segments.
The LineSegment class does not contain a property for the starting point of the line. The starting point of the line is the end point of the previous segment, or the StartPoint of the PathFigure if no other segments exist.
The simple shape of a line can also be generated using Line. LineSegment is particularly intended for drawing a line within what is typically a more complex geometry group.
Examples
The following example creates a simple PathGeometry made up of a single PathFigure with a LineSegment and displays it using a Path element. The PathFigure object's StartPoint is set to 10,20 and a LineSegment is defined with an end point of 100,130. The following illustration shows the PathGeometry created by this example.
