Remarks

A displacement link is a type of graphic element that supports the IDisplacementLink interface.

[C#]

You can differentiate displacement links from other graphic elements by using C#'s is keyword. The following code shows an example of this.

public void GetLink()
{
  //You can get app from ICommand :: OnCreate() hook parameter
  IMxDocument mxDoc = app.Document as IMxDocument;
  IGraphicsContainer graphicsContainer = mxDoc.FocusMap() as IGraphicsContainer;
  graphicsContainer.Reset();

  IElement element = graphicsContainer.Next();
  while (element != null)
  {
    if (element is IDisplacementLinkElement)
    { 
      //Do something with the link.
    }
    element = graphicsContainer.Next();
  }
}
[Visual Basic .NET]

You can differentiate displacement links from other graphic elements by using VBNet's TypeOf keyword. The following code shows an example of this.

  Public Sub GetLink()
    'You can get app from ICommand :: OnCreate() hook parameter
    Dim mxDoc As IMxDocument = TryCast(app.Document, IMxDocument)
    Dim graphicsContainer As IGraphicsContainer = TryCast(mxDoc.FocusMap(), IGraphicsContainer)
    graphicsContainer.Reset()

    Dim element As IElement = graphicsContainer.Next()
    While Not element Is Nothing
      If TypeOf element Is IDisplacementLinkElement Then
        'Do something with the link.
      End If
      element = graphicsContainer.Next()
    End While
  End Sub
