    GeometryType Property (Geometry)
    In This Topic
    Gets the geometry type of the instance.
    Syntax
    public abstract GeometryType GeometryType {get;}
    Public MustOverride ReadOnly Property GeometryType As GeometryType
    Example
    Get the individual parts of a multipart feature
    /// <summary>
    /// This method takes an input multi part geometry and breaks the parts into individual standalone geometries.
    /// This method must be called on the MCT. Use QueuedTask.Run.
    /// </summary>
    /// <param name="inputGeometry">The geometry to be exploded into the individual parts.</param>
    /// <returns>An enumeration of individual parts as standalone geometries. The type of geometry is maintained, i.e.
    /// if the input geometry is of type Polyline then each geometry in the return is of type Polyline as well.
    /// If the input geometry is of type Unknown then an empty list is returned.</returns>
    /// <remarks>This method must be called on the MCT. Use QueuedTask.Run.</remarks>
