Get the lifeline type

To get the lifeline type, use the TypeModel property of the ILifelineShape object.

public void GetLifelineTypes(ICommandContext c, ICommandParams p) 
{ 
ISequenceDiagram sequenceDiagram = c.App.Workspace.CurrentEditor as ISequenceDiagram; 
if (sequenceDiagram == null) return; 

//Get the lifelines 
var lifelines = sequenceDiagram.Lifelines; 

var no = 1; 
foreach (ILifelineShape lifeline in lifelines) 
{ 
//Get the lifeline type 
IModel typeModel = lifeline.TypeModel; 
var typeModelName = typeModel != null ? typeModel.Name : "None"; 
c.App.Output.WriteLine("sample", $"{no}th lifeline type : {typeModelName}"); 
no++; 
} 
}
