ArcGIS Pro 3.3 API Reference Guide
ArcGIS.Core.Data.Analyst3D Namespace / LasPointCursor Class / MoveNext Method
Example

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

    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
    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())
      {

        {
    
        }
      }
    }
    
    // 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 classsification codes
    pointFilter = new ArcGIS.Core.Data.Analyst3D.LasPointFilter();
    pointFilter.FilterGeometry = envelope;
    pointFilter.ClassCodes = new List<int> { 4, 5 };

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