Parameters
- latitude
Type: System.Double
A double that specifies the latitude of a point in a geography figure.
- longitude
Type: System.Double
A double that specifies the longitude of a point in a geography figure.
- z
Type: System.Nullable<Double>
A double that specifies the altitude of a point in a geography figure. Is Nullable.
- m
Type: System.Nullable<Double>
A double that specifies the measure type for the point. Is Nullable.
Implements
IGeographySink.AddLine(Double, Double, Nullable<Double>, Nullable<Double>)
Remarks
Method is used together with BeginFigure() to construct the points of a geography type figure. BeginFigure() can only construct the starting endpoint for a geography type figure. Use AddLine() to construct additional points for the figure.
Method throws a FormatException when there is invalid input.
