ArcGIS.Core.Data.Exceptions.GeodatabaseException	A geodatabase-related exception has occurred.
ArcGIS.Core.CalledOnWrongThreadException	This method or property must be called within the lambda passed to QueuedTask.Run

Remarks

TIN elements can exist "inside" or "outside" the TIN's data area. When TINs are initially built the only elements that are "outside" are the four super nodes and their incident edges and triangles. If clip or erase polygons are added to a TIN, they further modify what is considered to be "inside" or "outside".

When looping through the nodes, the loop starts at index = 1.

Example

{
  var nodeCount = tinDataset.GetNodeCount();
  var outsideNodeCount = tinDataset.GetOutsideNodeCount();
  var edgeCount = tinDataset.GetEdgeCount();
  var outsideEdgecount = tinDataset.GetOutsideEdgeCount();
  var triCount = tinDataset.GetTriangleCount();
  var outsideTriCount = tinDataset.GetOutsideTriangleCount();
}
