IMultiLineString

A collection of linestrings. In addition to the other properties inherited from IGeometry, multilinestrings have length.

	Properties
	Count	Gets the number of linestrings in the collection. (Inherited from IGeometryCollection)
	Dimension	Gets the dimension of the multilinestring. (Inherited from IGeometry)
	Envelope	Gets the multilinestring’s bounding box. The envelope of a multilinestring is the non-intersected endpoints of the linestring elements. Returns NULL if all the endpoints of all the linestrings are intersected. (Inherited from IGeometry)
	Geometry	Gets an IGeometry, representing a specific multiline in the collection.
	GeometryType	Gets the geometry type ID. (Inherited from IGeometry)
	GeometryTypeStr	Gets a string representation of the geometry type. (Inherited from IGeometry)
	Item	Gets the data stored in the specified zero-based index. (Inherited from IGeometryCollection)
	Length	Gets the length of the multiline string.
	NumGeometries	Gets the number of linestrings in this multilinestring collection. (Inherited from IGeometryCollection)
	SpatialOperator	An ISpatialOperator representing the multilinestring’s interaction with another geometry object. (Inherited from IGeometry)
	SpatialRelation	An ISpatialRelation that tests the multilinestring’s spatial relationship with other geometries. (Inherited from IGeometry)
	Wks	An IWks representing methods for transferring coordinate system information (WKT and WKB). (Inherited from IGeometry)
	Methods
	AddGeometry	Adds a linestring to the collection. (Inherited from IGeometryCollection)
	Clone	Returns an exact copy of the selected multilinestring (Inherited from IGeometry)
	DeleteGeometry	Deletes the selected linestring from the collection. (Inherited from IGeometryCollection)
	EndEdit	Terminates the edit item mode. (Inherited from IGeometry)
	IsClosed	Gets a Boolean determining if the multilinestring is closed. A multilinestring is closed if all its linestring elements are closed.
	IsEmpty	Returns whether or not the collection is empty. (Inherited from IGeometry)
	IsSimple	Returns whether or not the geometry collection is simple. Multilinestrings are simple if they only intersect at the endpoints of the linestring elements, and non-simple if they intersect in the middle of a linestring. (Inherited from IGeometry)
	SetEmpty	Removes all linestrings from this collection. (Inherited from IGeometry)
	StartEdit	Starts the edit item mode. (Inherited from IGeometry)

Geometry

Gets an IGeometry, representing a specific multiline in the collection. This property is exposed in C# and JavaScript in the following ways:

§ In C#, this property is exposed as Geometry, e.g.,

IMultiLineString myMultiLineString;

IGeometry thisGeometry = myMultiLineString.Geometry[0];

Note: In older versions of C#, this property is exposed as get_Geometry, e.g.,

IMultiLineString myMultiLineString;

IGeometry thisGeometry = myMultiLineString.get_Geometry[0];

§ In JavaScript use:

var myMultiLineString;

var thisGeometry = myMultiLineString.Geometry(0);

JavaScript
Geometry

C#
IGeometry Geometry { get; }

C++

HRESULT Geometry ([in] long Index,

[out, retval] IGeometry** pVal)

Length

Gets the length of the multiline string.

JavaScript
Length

C#
double Length { get; }

C++
HRESULT Length([out, retval] double* dLength)

IsClosed

Gets a Boolean determining if the multiline string is closed.

JavaScript

IsClosed(

IsClosed)

void IsClosed(

ref bool IsClosed)

C++

HRESULT IsClosed(

VARIANT_BOOL* IsClosed)

Parameters

IsClosed

A Boolean that indicates if the multiline is closed.

Exceptions
