ArcGIS Pro 3.4 API Reference Guide
ArcGIS.Core.Data.Analyst3D Namespace / LasPointCursor Class / MoveNext Method
Example Version

MoveNext Method (LasPointCursor)
Advances to the next LasPoint in this LasPointCursor. This method must be called on the MCT. Use QueuedTask.Run.
Syntax
public bool MoveNext()

Return Value

true if the cursor has successfully advanced to the next point; false if the cursor has passed the end of the collection.
Exceptions
ExceptionDescription
This instance has already called MoveNextArray. Call Reset before using this method.
A geodatabase-related exception has occurred.
Remarks
If MoveNext() returns true, a LasPoint object is created. Even if this point (Current) is not otherwise needed, it should be properly disposed through a call to System.IDisposable.Dispose or with the use of a using statement.
Example
Search LAS Points
// search all points
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDataset.SearchPoints(null))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

// search within an extent
ArcGIS.Core.Data.Analyst3D.LasPointFilter pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
pointFilter.FilterGeometry = envelope;
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDataset.SearchPoints(pointFilter))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

// search within an extent and limited to specific classification codes
pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
pointFilter.FilterGeometry = envelope;
pointFilter.ClassCodes = new List<int> { 4, 5 };
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDataset.SearchPoints(pointFilter))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}
Search for LAS Points
// searching on the LasDatasetLayer will honor any LasPointDisplayFilter

// search all points
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDatasetLayer.SearchPoints(null))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

// search within an extent
ArcGIS.Core.Data.Analyst3D.LasPointFilter pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
pointFilter.FilterGeometry = envelope;
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDatasetLayer.SearchPoints(pointFilter))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}

// search within an extent and limited to specific classification codes
pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
pointFilter.FilterGeometry = envelope;
pointFilter.ClassCodes = new List<int> { 4, 5 };
using (ArcGIS.Core.Data.Analyst3D.LasPointCursor ptCursor = lasDatasetLayer.SearchPoints(pointFilter))
{
  while (ptCursor.MoveNext())
  {
    using (ArcGIS.Core.Data.Analyst3D.LasPoint point = ptCursor.Current)
    {

    }
  }
}
