由于要给客户做培训，关于sharepoint 2010 工作流的，打算在网上找个demo看看的，结果这方面的demo 还比较少，只能自己折腾了

哎，谁叫客户就是上帝嘛。 开始打算用顺序流的，发现网上这方面的资料比较多，而且顺序流不能体现实际的业务，看起来太“土”。。。。

状态机流程图

首先申请人---〉操作员审批----领导审批---结束

当然还有拒绝的动作，我就不在这里说明了，大家看图·

申请表单

审批表单

流程结束

设计这个流程的时候，发现和2007的版本一样，在基于VS这块，无论顺序还是状态流程，貌似变化不大@

开发sharepoint 2010 工作流 需要注意这个配置xml

尤其是这个内容ID

后台aspx页面像Workflow传送value的时候可以通过

 Hashtable htData = new Hashtable();
                htData["TaskData"] = "true";

这个hashtable来做

SPWorkflowTask.AlterTask(this.taskItem, htData, true);

可以把value传送给工作流

在流程里面取值：

在审批动作里面直接这样取

   private void onTaskChanged1_Invoked(object sender, ExternalDataEventArgs e)
        {

            this.IsOperatorPenson = bool.Parse(this.afterProperties1.ExtendedProperties["TaskData"].ToString());
            this.leaderPenson = this.afterProperties1.ExtendedProperties["ApproveUser"].ToString();
            this.auditComments = this.afterProperties1.ExtendedProperties["Comments"].ToString();
        }

需要代码学习的，可以留下邮箱，我稍后也会把代码上传的

困。。。
