參數
- x
型別：System.Double
A double that specifies the x-coordinate of a point in a geometry figure.
- y
型別：System.Double
A double that specifies the y-coordinate of a point in a geometry figure.
- z
型別：System.Nullable<Double>
A double that specifies the z-coordinate of a point in a geometry figure. Is Nullable.
- m
型別：System.Nullable<Double>
A double that specifies the measure for the point. Is Nullable.
實作
IGeometrySink.AddLine(Double, Double, Nullable<Double>, Nullable<Double>)
備註
Method is used together with BeginFigure() to construct the points of a geometry type figure. BeginFigure() can only construct the starting endpoint for a geometry type figure. Use AddLine() to construct additional points for the figure.
Method throws a FormatException when there is invalid input.
