以下是使用代码审批、转签k2 blackpearl流程,初探K2 Blackpearl,望高人多多包涵、指点.
//执行动作
private void MyAction(string argAction)
{
//创建连接对象
SourceCode.Workflow.Client.Connection wfcon = new SourceCode.Workflow.Client.Connection();
//打开K2连接
string k2Server = System.Configuration.ConfigurationManager.AppSettings["K2Server"];
string workflowServicePort = System.Configuration.ConfigurationManager.AppSettings["WorkflowServicePort"];
wfcon.Open(k2Server + ":" + workflowServicePort); //当前用户打开
wfcon.ImpersonateUser(HttpContext.Current.User.Identity.Name); //获取流程列表
SourceCode.Workflow.Client.WorklistItem worklistitem = wfcon.OpenWorklistItem(SN); /*
//获取流程实例编号
string[] _SN = SN.Split('_');
int _ID = int.Parse(_SN[0]);
//获取流程实例
SourceCode.Workflow.Client.ProcessInstance proInst = wfcon.OpenProcessInstance(_ID);
//DataFields赋值
proInst.DataFields["TaskUsers"].Value = ddlTaskUsers.SelectedValue;
//更新DataFields
procinst.Update();
*/ //查找action(执行动作)
foreach (SourceCode.Workflow.Client.Action action in worklistitem.Actions)
{
if (action.Name.Equals(argAction))
{
//执行动作
action.Execute();
}
}
wfcon.Dispose();
} //转签
protected void ProcRedirect(string argEmpName)
{
//创建连接对象
SourceCode.Workflow.Client.Connection wfcon = new SourceCode.Workflow.Client.Connection(); //打开K2连接
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); //获取流程列表
SourceCode.Workflow.Client.WorklistItem worklistitem = wfcon.OpenWorklistItem(SN);
//转签
worklistitem.Redirect(argEmpName);
//释放资源
wfcon.Dispose();
}
流程图如下:
