使用C#代碼審批/轉籤K2 Blackpearl流程

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

 

//執行動做
        private void MyAction(string argAction)
        {
            //建立鏈接對象
            SourceCode.Workflow.Client.Connection wfcon = new SourceCode.Workflow.Client.Connection();
            //打開K2鏈接
            string k2Server = System.Configuration.ConfigurationManager.AppSettings["K2Server"];
            string workflowServicePort = System.Configuration.ConfigurationManager.AppSettings["WorkflowServicePort"];
            wfcon.Open(k2Server + ":" + workflowServicePort);
            
            //當前用戶打開
            wfcon.ImpersonateUser(HttpContext.Current.User.Identity.Name);

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

            /*
            //獲取流程實例編號
            string[] _SN = SN.Split('_');
            int _ID = int.Parse(_SN[0]);
            //獲取流程實例
            SourceCode.Workflow.Client.ProcessInstance proInst = wfcon.OpenProcessInstance(_ID);
            //DataFields賦值
            proInst.DataFields["TaskUsers"].Value = ddlTaskUsers.SelectedValue;
            //更新DataFields
            procinst.Update();
            */

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

        //轉籤
        protected void ProcRedirect(string argEmpName)
        {
            //建立鏈接對象
            SourceCode.Workflow.Client.Connection wfcon = new SourceCode.Workflow.Client.Connection();
            
            //打開K2鏈接
            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);

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