Geometry DropMs( 
   Geometry geometry
)

Function DropMs( _
   ByVal geometry As Geometry _
) As Geometry

Parameters

geometry: The input geometry.

Return Value

The geometry with the M-values set to NaN. If the geometry is empty or the spatial reference is null, then the input geometry is returned unchanged.

Exceptions

Exception	Description
System.ArgumentNullException	Geometry is null.
System.InvalidOperationException	This geometry is not M-Aware.
System.NotImplementedException	The method is not implemeted for GeometryBag.

Example

Set all the M-values to NaN - DropMs

string json = "{\"hasM\":true,\"paths\":[[[-4,2,1],[-4,5,2],[-2,5,3],[-2,7,4],[2,7,5]],[[4,1,-1],[2,1,-2],[2,-2,-3],[-3,-2,-4],[-3,0,-5]]]}}";
Polyline polyline = PolylineBuilderEx.FromJson(json);
Polyline outputPolyline = GeometryEngine.Instance.DropMs(polyline) as Polyline;
// outputPolyline.HasM = true. Every M-value is NaN.
// outputPolyline.ToJson() = {"hasM":true,"paths":[[[-4,2,null],[-4,5,null],[-2,5,null],[-2,7,null],[2,7,null]],[[4,1,-null],[2,1,null],[2,-2,null],[-3,-2,null],[-3,0,null]]]}
