ArcGIS Pro 3.2 API Reference Guide
ArcGIS.Core.Geometry Namespace / Envelope Class / IDMax Property
Example

In This Topic
    IDMax Property (Envelope)
    In This Topic
    Gets the ID maximum of this instance.
    Syntax
    public int IDMax {get;}
    Public ReadOnly Property IDMax As Integer
    Remarks
    Zero is returned if no ID's are defined in the envelope.
    Example
    Union two Envelopes
    // use the convenience builders
    Envelope env1 = EnvelopeBuilderEx.CreateEnvelope(0, 0, 1, 1, SpatialReferences.WGS84);
    Envelope env2 = EnvelopeBuilderEx.CreateEnvelope(0.5, 0.5, 1.5, 1.5, SpatialReferences.WGS84);
    
    Envelope env3 = env1.Union(env2);
    
    double area = env3.Area;
    double depth = env3.Depth;
    double height = env3.Height;
    double width = env3.Width;
    double len = env3.Length;
    
    MapPoint centerPt = env3.Center;
    Coordinate2D coord = env3.CenterCoordinate;
    
    bool isEmpty = env3.IsEmpty;
    int pointCount = env3.PointCount;
    
    // coordinates
    //env3.XMin, env3.XMax, env3.YMin, env3.YMax
    //env3.ZMin, env3.ZMax, env3.MMin, env3.MMax
    
    bool isEqual = env1.IsEqual(env2);    // false
    
    // or use the builderEx constructors which don't need to run on the MCT.
    EnvelopeBuilderEx builderEx = new EnvelopeBuilderEx(0, 0, 1, 1, SpatialReferences.WGS84);
    builderEx.Union(env2);      // builder is updated to the result
    
    depth = builderEx.Depth;
    height = builderEx.Height;
    width = builderEx.Width;
    
    centerPt = builderEx.Center;
    coord = builderEx.CenterCoordinate;
    
    isEmpty = builderEx.IsEmpty;
    
    env3 = builderEx.ToGeometry() as Envelope;
