Here's the code to get the annotations and go to the annotations

/// <summary>        ///get PDF Annotations/// </summary>        /// <param name= "Sender" ></param>        /// <param name= "E" ></param>        Private voidBtnattachmentannotation_click (Objectsender, EventArgs e) {             This. Tablelayoutpanel1.setrowspan ( This. PdfDocumentViewer1,1);  This. m_isattachmentannotation =true;  This. listview1.visible =true;  This. ListView1.Items.Clear ();  This. ListView1.Columns.Clear (); if( This. pdfdocumentviewer1.isdocumentloaded && This. Pdfdocumentviewer1.pagecount >0)            {                 This. Listview1.view =View.Details;  This. LISTVIEW1.COLUMNS.ADD ("Annotations", $);  This. LISTVIEW1.COLUMNS.ADD ("content", the);  This. LISTVIEW1.COLUMNS.ADD ("Page Number", the);  This. LISTVIEW1.COLUMNS.ADD ("location", the); //get a list of PDF annotationspdfdocumentattachmentannotation[] Annotations = This. Pdfdocumentviewer1.getattachmentannotaions (); if(Annotations! =NULL&& annotations. Length >0)                {                    //Annotation Properties                     for(inti =0; I < annotations. Length; i++) {pdfdocumentattachmentannotation annotation=Annotations[i]; ListViewItem Item=NewListViewItem (annotation.                        FileName); Item. SubItems.Add (annotation.                        Text); Item. SubItems.Add (annotation.                        Pageindex.tostring ()); Item. SubItems.Add (annotation.                        Location.tostring ()); Item. Tag=annotation;  This. LISTVIEW1.ITEMS.ADD (item); }                }            }        }        /// <summary>        ///go to Annotations/// </summary>        /// <param name= "Sender" ></param>        /// <param name= "E" ></param>        Private voidListview1_click (Objectsender, EventArgs e) {            if( This. M_isattachmentannotation) {pdfdocumentattachmentannotation annotation= (pdfdocumentattachmentannotation) This. listview1.selecteditems[0].                Tag;  This. pdfdocumentviewer1.gotoattachmentannotation (annotation); }        }
