Parameter

• x
  Typ: System.Double
  A double that specifies the x-coordinate of a point in a geometry figure.

• y
  Typ: System.Double
  A double that specifies the y-coordinate of a point in a geometry figure.

• z
  Typ: System.Nullable<Double>
  A double that specifies the z-coordinate of a point in a geometry figure. Is Nullable.

• m
  Typ: System.Nullable<Double>
  A double that specifies the measure for the point. Is Nullable.

Implementiert

IGeometrySink.AddLine(Double, Double, Nullable<Double>, Nullable<Double>)

Hinweise

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.
