【轉載】使用C#代碼審批/轉簽K2 Blackpearl流程

以下是使用代碼審批、轉簽k2 blackpearl流程，初探K2 Blackpearl，望高人多多包涵、指點. 

 

　//執行動作
        private void MyAction(string argAction)
        {
            //建立連線物件
            SourceCode.Workflow.Client.Connection wfcon = new SourceCode.Workflow.Client.Connection();
            //開啟K2串連
            string k2Server = System.Configuration.ConfigurationManager.AppSettings["K2Server"];
            string workflowServicePort = System.Configuration.ConfigurationManager.AppSettings["WorkflowServicePort"];
            wfcon.Open(k2Server + ":" + workflowServicePort);
            
            //目前使用者開啟
            wfcon.ImpersonateUser(HttpContext.Current.User.Identity.Name);

            //擷取流程列表
            SourceCode.Workflow.Client.WorklistItem worklistitem = wfcon.OpenWorklistItem(SN);

            /*
            //擷取流程執行個體編號
            string[] _SN = SN.Split('_');
            int _ID = int.Parse(_SN[0]);
            //擷取流程執行個體
            SourceCode.Workflow.Client.ProcessInstance proInst = wfcon.OpenProcessInstance(_ID);
            //DataFields賦值
            proInst.DataFields["TaskUsers"].Value = ddlTaskUsers.SelectedValue;
            //更新DataFields
            procinst.Update();
            */

            //尋找action(執行動作)
            foreach (SourceCode.Workflow.Client.Action action in worklistitem.Actions)
            {
                if (action.Name.Equals(argAction))
                {
                    //執行動作
                    action.Execute();
                }
            }
            wfcon.Dispose();
        }

        //轉簽
        protected void ProcRedirect(string argEmpName)
        {
            //建立連線物件
            SourceCode.Workflow.Client.Connection wfcon = new SourceCode.Workflow.Client.Connection();
            
            //開啟K2串連
            string k2Server = System.Configuration.ConfigurationManager.AppSettings["K2Server"];
            string workflowServicePort = System.Configuration.ConfigurationManager.AppSettings["WorkflowServicePort"];
            wfcon.Open(k2Server + ":" + workflowServicePort);

            wfcon.ImpersonateUser(HttpContext.Current.User.Identity.Name);

            //擷取流程列表
            SourceCode.Workflow.Client.WorklistItem worklistitem = wfcon.OpenWorklistItem(SN);
            //轉簽
            worklistitem.Redirect(argEmpName);
            //釋放資源
            wfcon.Dispose();  }
