    m As Nullable(Of Double) _
)
用法
Dim instance As IGeographySink
Dim latitude As Double
Dim longitude As Double
Dim z As Nullable(Of Double)
Dim m As Nullable(Of Double)

instance.BeginFigure(latitude, longitude, _
    z, m)

void BeginFigure(
    double latitude,
    double longitude,
    Nullable<double> z,
    Nullable<double> m
)

void BeginFigure(
    double latitude, 
    double longitude, 
    Nullable<double> z, 
    Nullable<double> m
)

abstract BeginFigure : 
        latitude:float * 
        longitude:float * 
        z:Nullable<float> * 
        m:Nullable<float> -> unit 

function BeginFigure(
    latitude : double, 
    longitude : double, 
    z : Nullable<double>, 
    m : Nullable<double>
)

参数

  • latitude
    类型：System. . :: . .Double
    A double that specifies the latitude of the starting endpoint in a geography figure.
  • longitude
    类型：System. . :: . .Double
    A double that specifies the longitude of the starting endpoint in a geography figure.
  • z
    类型：System. . :: . .Nullable< (Of < ( <'Double> ) > ) >
    A double that specifies the altitude of the starting endpoint in a geography figure. Is Nullable.

注释

Method must be used together with the EndFigure() method.
