Get messages

Get all messages from a sequence diagram

To get all messages, use the Messages property of the ISequenceDiagram object.

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

//Get messages 
IMessageShapeCollection messages = sequenceDiagram.Messages; 

var no = 1; 
foreach (IMessageShape message in messages) 
{ 
c.App.Output.WriteLine("sample", $"{no}th message : {message.Text}"); 
no++; 
} 
} 

Get sent messages from a specific lifeline

An example of getting sent messages from a specific lifeline.

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

//Get the send messages from the execution specifications of the selected lifeline 
ILifelineShape lifeline = sequenceDiagram.GetSelectedShapes().FirstOrDefault() as ILifelineShape; 
IMessageShapeCollection sendMessages = lifeline.ExecutionSpecifications.SelectMany(ec => ec.SendMessages); 

c.App.Output.WriteLine("sample", $"Lifeline: Send Messages for {lifeline.Text}"); 

var no = 1; 
foreach (IMessageShape sendMessage in sendMessages) 
{ 
c.App.Output.WriteLine("sample", $" {no}th sent message: {sendMessage.Text}");
