    Syntax
    public void SetActiveSurfaceConstraints( 
       List<string> surfaceConstraintNames
    )
    Public Sub SetActiveSurfaceConstraints( _
       ByVal surfaceConstraintNames As List(Of String) _
    ) 

    Parameters

    surfaceConstraintNames
    A list of the dataset names that are surface constraints. If null, then all constraints are cleared.
    Exceptions

    Example
    Active Surface Constraints
    var activeSurfaceConstraints = lasDatasetLayer.GetActiveSurfaceConstraints();
    
    // clear all surface constraints (i.e. none are active)
    lasDatasetLayer.SetActiveSurfaceConstraints(null);
    
    // set all surface constraints active
    using (var lasDataset = lasDatasetLayer.GetLasDataset())
    {
      var surfaceConstraints = lasDataset.GetSurfaceConstraints();
      var names = surfaceConstraints.Select(sc => sc.DataSourceName).ToList();
      lasDatasetLayer.SetActiveSurfaceConstraints(names);
    }
