Csom code which uses workflow.asmx [please help how to terminate a workflow on a perticular list item by csom code]

Hi All,

please help how to terminate a workflow on a perticular list item by csom code.

Description:

I am writing a CSOM code which connect to a site and then list and find all the list items for which already running workflow is throwing error if status is error then cancel/terminate the workflow and retrigger it.

Status :

I got below reference from a site and come to know in csom code I need to use workflow.asmx web service and then get template id to terminate WF from list item.

Please can someone guide and give me sample code for this?

Code:

public static void GetWorkflowStatus(string strLibName, string strWFTitle)
        {
            List list = cc.Web.Lists.GetByTitle(strLibName);
            cc.Load(list);
            cc.ExecuteQuery();

            string strWorkFlowStatusColName = Constant.WA_WORKFLOW_STATUS_COL_INT_NAME;

            CamlQuery query = new CamlQuery();


            query.ViewXml="<View Scope='RecursiveAll'><Query><Where><Eq><FieldRef Name='" + strWorkFlowStatusColName + "' /><Value Type='WorkflowStatus'>" + 3 + "</Value></Eq></Where></Query><ViewFields><FieldRef Name='Title'/><FieldRef Name='" + strWorkFlowStatusColName + "'/><FieldRef Name='ID'/></ViewFields></View>";




            ListItemCollection itemCollection = list.GetItems(query);
            cc.Load(itemCollection);
            cc.ExecuteQuery();

            if (itemCollection.Count > 0)
            {
                Utility.CSVWriter("Workflow Error Occurred Item Count: " + itemCollection.Count, LogReport);

                foreach (ListItem objItem in itemCollection)
                {
                    try
                    {
                        if (objItem.FileSystemObjectType.Equals(FileSystemObjectType.File))
                        {
                            ListItem wfStatusFldItm = objItem.File.ListItemAllFields;
                            cc.Load(wfStatusFldItm);
                            cc.ExecuteQuery();

                            if (wfStatusFldItm[strWorkFlowStatusColName] != null && Constant.WA_WORKFLOW_ERR_OCC_STATUS_CODE.Equals(wfStatusFldItm[strWorkFlowStatusColName].ToString()))
                            {
                                string statusValue = wfStatusFldItm[strWorkFlowStatusColName].ToString();
                                Utility.CSVWriter("Result for Item ID " + wfStatusFldItm["ID"] + " :" + statusValue, LogReport);

                                //New code after adding Workflow web service
                                Workflow ws = new Workflow();
                                ws.Url = "http://sp2010hvpkdev08:6789/sites/qr/_vti_bin/workflow.asmx";
                                ws.Credentials = CredentialCache.DefaultCredentials;
                                                          }

                        }
                    }
                    catch (Exception ex)
                    {
                        Utility.CSVWriter("Error while getting item status.", LogReport);
                        Utility.CSVWriter(ex.Message, LogReport);
                    }
                }
            }
            else
            {
                Utility.CSVWriter("No error occurred Workflow items are found.", LogReport);
            }
        }
