在介绍完表单类的时候，接下来介绍工作流引擎，主要由四个类组成，分别是流程、流程步骤、流程实例、流程步骤实例类。
流程类：
1 [Serializable]
2 public class Flow
3 {
4 [XmlAttribute]
5 public Guid FlowId { get; set; }

50 return RequestRights+": ";
51 }
52 }
53 }
54
55 [XmlAttribute]
56 public string RoleGroups {
57 get
58 {
59 if (!string.IsNullOrEmpty(RequestGroup))
60 {
61 return string.Join("、", RequestGroup.Split(‘,‘).Select(g => g.Split(‘|‘)[0]));
62 }
63 else
64 {
65 return string.Empty;
66 }
67 }
68 }
69 }
流程步骤类：

16
17 public string FlowStatusName
18 {
19 get
20 {
21 switch (FlowStatus)
22 {
23 case WorkflowConstant.SignatureStatus.Start:
24 return "进行中";
25 break;
26 case WorkflowConstant.SignatureStatus.Undeal:
27 return "未处理";
28 break;
29 case WorkflowConstant.SignatureStatus.PartialPassed:
30 return "部分通过";
31 break;
32 case WorkflowConstant.SignatureStatus.Passed:
33 return "通过";
34 break;
35 case WorkflowConstant.SignatureStatus.OutDated:
36 return "过期";
37 break;
38 case WorkflowConstant.SignatureStatus.Canceled:
39 return "取消";
40 break;
41 case WorkflowConstant.SignatureStatus.RejectToPreviousStep:
42 return "退回上一步";
43 break;
44 case WorkflowConstant.SignatureStatus.RejectToFirstStep:
45 return "退回第一步";
46 break;
47 case WorkflowConstant.SignatureStatus.Stopped:
48 return "停止";
49 break;
50 case WorkflowConstant.SignatureStatus.Finish:
51 return "结束";
52 break;
53 default:
54 return string.Empty;
55 }
56 }
57 }
58
59 public DateTime? EndDate
60 {
61 get
62 {
63 if (Flow != null)
64 {
65 return CreateDate.AddDays(Flow.PeriodTime);
66 }
67 else return null;
68 }
69 }
70
71 public string CurrentStepDisplayName { get; set; }
72 }
流程步骤实例类：
1 [Serializable]
2 public class FlowInstanceStep
3 {
4 [XmlAttribute]
5 public Guid StepInstanceId { get; set; }
6 public List<WorkflowPersonSignature> PersonSignatures { get; set; }
7
8 public SerializableDictionary<Guid, string> WriteValues { get; set; }
9
10 public FlowStep FlowStep { get; set; }
11 [XmlAttribute]
12 public DateTime CreateDate { get; set; }
13 [XmlAttribute]
14 public DateTime ProcessDate { get; set; }
15 [XmlAttribute]
16 public WorkflowConstant.SignatureStatus StepStatus { get; set; }
17 public List<AttachFile> FileList { get; set; }
18 }
设定好流程和步骤，以后每次建立的流程实例都是从流程获取到的。
