演示
此示例演示如何使用 SetStateRequest 消息，通过激活和停用工作流来更改工作流的状态。 此外，该示例还演示如何创建自定义 XAML 工作流。 首先显示仅包含示例关键部分的片段，后面再显示完整示例代码。
示例
演示如何激活和停用工作流的代码段。
var activateRequest = new SetStateRequest
{
EntityMoniker = new EntityReference
(Workflow.EntityLogicalName, _workflowId),
State = new OptionSetValue((int)WorkflowState.Activated),
Status = new OptionSetValue((int)workflow_statuscode.Activated)
};
_serviceProxy.Execute(activateRequest);
SetStateRequest deactivateRequest = new SetStateRequest
{
EntityMoniker =
new EntityReference(Workflow.EntityLogicalName, _workflowId),
State = new OptionSetValue((int)WorkflowState.Draft),
Status = new OptionSetValue((int)workflow_statuscode.Draft)
};
_serviceProxy.Execute(deactivateRequest);
示例
演示如何创建 XAML 工作流的代码段。
Workflow workflow = new Workflow()
{
Name = "CreateTaskXAML",
Type = new OptionSetValue((int)WorkflowType.Definition),
Category = new OptionSetValue((int)WorkflowCategory.Workflow),
Scope = new OptionSetValue((int)WorkflowScope.User),
LanguageCode = 1033, // U.S. English
TriggerOnCreate = true,
OnDemand = true,
PrimaryEntity = Lead.EntityLogicalName,
Description =
"Test workflow for the SetStateWorkflow SDK sample",
Xaml = xamlWF
};
_workflowId = _serviceProxy.Create(workflow);
