I am asking this question as I do not have any experience in VB.NET coding. I tried to follow ESRI help but I did not quite understand it. I have 5 points with X,Y and Z dimensions.

How to add these 5 points to make a TIN?

I want VB.NET code.

    There really isn't much point in generating a TIN with five vertices -- If you had 500, or 5000, or 50000 points it would be a different situation. Learning VB.Net is yet another issue, and not particularly GIS-centric.

  • If you know the nodes and elements, you can generate your own TIN definition with LandXML (see this), then use the LandXMLToTin_3d tool in one of many ways.

The best recommendation I can give is don't. Creating a TIN using ArcObjects is a tedious process.

You would be best looking at IGeoprocessor and calling the existing tools. If you have 5 points in memory then write them to a new shape file and create the TIN from points.
