IGeometrySink.AddLine 方法
Defines points other than the starting endpoint in a geometry instance. This API is obsolete. IGeometrySink110 should be used instead.

參數
- x
型別：System.Double
A double that specifies the x-coordinate of a point in a geometry instance.
- y
型別：System.Double
A double that specifies the y-coordinate of a point in a geometry instance.
- z
型別：System.Nullable<Double>
A double that specifies the z-coordinate of a point in a geometry instance. Is Nullable.
- m
型別：System.Nullable<Double>
A double that specifies the measure for the point. Is Nullable.
備註
Use this method together with the BeginFigure method to define the points of a geometry instance. The BeginFigure method can only define the starting endpoint for a geometry instance, whereas the AddLine method to defines additional points for the figure.
