Get port information

Ports on a diagram's node shape can be accessed through the Ports property of the INode object obtained from IDiagram.

Access each port on a node

An example of enumerating the ports on the selected node shape of a diagram.

public void EnumeratePorts(ICommandContext c, ICommandParams p) 
{ 
IDiagram diagram = c.App.Workspace.CurrentEditor as IDiagram; 
if (diagram == null) return; 

//Get the selected nodes 
var nodes = diagram.GetSelectedShapes().OfType<INode>(); 

//Process each node 
foreach (INode node in nodes) 
{ 
c.App.Output.WriteLine("sample", $"Node model : {node.Model.Name}"); 

//Process each port that the node has 
foreach (IPort port in node.Ports) 
{ 
c.App.Output.WriteLine("sample", $"Port model : {port.Model.Name}"); 
} 
} 
}
