在sharepoint designer的工作流程编辑器中，我如何获得工作流启动器用户名？

在Sharepoint设计师的工作流编辑器中，我希望检索工作流启动者的用户名/名称（即谁启动它或触发工作流） - 使用第三方产品（例如Nintex Workflow 2007（其中I将使用类似{常见：启动器}） - 但我似乎无法找到任何方式开箱做到这一点使用共享点设计器和MOSS 2007在sharepoint designer的工作流程编辑器中，我如何获得工作流启动器用户名？

它不看起来像这个相当明显的功能是支持OOTB的，所以我最终编写了一个自定义活动（如其中一个答案所示）。我在这里列出的活动代码，以供参考，虽然我怀疑有可能是这个漂浮在那里在博客上，因为它是一个非常平凡解的几个实例：

public partial class LookupInitiatorInfo : Activity 
{ 
    public static DependencyProperty __ActivationPropertiesProperty = 
     DependencyProperty.Register("__ActivationProperties", 
     typeof(Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties), 
     typeof(LookupInitiatorInfo)); 

    public static DependencyProperty __ContextProperty = 
     DependencyProperty.Register("__Context", typeof (WorkflowContext), 
     typeof (LookupInitiatorInfo)); 

    public static DependencyProperty PropertyValueVariableProperty = 
     DependencyProperty.Register("PropertyValueVariable", typeof (string),  
     typeof(LookupInitiatorInfo)); 

    public static DependencyProperty UserPropertyProperty = 
     DependencyProperty.Register("UserProperty", typeof (string), 
     typeof (LookupInitiatorInfo)); 

    public LookupInitiatorInfo() 
    { 
     InitializeComponent(); 
    } 

    [Description("ActivationProperties")] 
    [ValidationOption(ValidationOption.Required)] 
    [Browsable(true)] 
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)] 
    public Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties __ActivationProperties 
    { 
     get { return ((Microsoft.SharePoint.Workflow.SPWorkflowActivationProperties)(base.GetValue(__ActivationPropertiesProperty))); } 
     set { base.SetValue(__ActivationPropertiesProperty, value); } 
    } 

    [Description("Context")] 
    [ValidationOption(ValidationOption.Required)] 
    [Browsable(true)] 
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)] 
    public WorkflowContext __Context 
    { 
     get { return ((WorkflowContext)(base.GetValue(__ContextProperty))); } 
     set { base.SetValue(__ContextProperty, value); } 
    } 

    [Description("UserProperty")] 
    [ValidationOption(ValidationOption.Required)] 
    [Browsable(true)] 
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)] 
    public string UserProperty 
    { 
     get { return ((string) (base.GetValue(UserPropertyProperty))); } 
     set { base.SetValue(UserPropertyProperty, value); } 
    } 

    [Description("PropertyValueVariable")] 
    [ValidationOption(ValidationOption.Required)] 
    [Browsable(true)] 
    [DesignerSerializationVisibility(DesignerSerializationVisibility.Visible)] 
    public string PropertyValueVariable 
    { 
     get { return ((string) (base.GetValue(PropertyValueVariableProperty))); } 
     set { base.SetValue(PropertyValueVariableProperty, value); } 
    } 

    protected override ActivityExecutionStatus Execute(ActivityExecutionContext executionContext) 
    { 
     // value values for the UserProperty (in most cases you 
     // would use LoginName or Name) 

     //Sid 
     //ID 
     //LoginName 
     //Name 
     //IsDomainGroup 
     //Email 
     //RawSid 
     //Notes 

     try 
     { 
      string err = string.Empty; 

      if (__ActivationProperties == null) 
      { 
       err = "__ActivationProperties was null"; 
      } 
      else 
      { 
       SPUser user = __ActivationProperties.OriginatorUser; 

       if (user != null && UserProperty != null) 
       { 
        PropertyInfo property = typeof (SPUser).GetProperty(UserProperty); 
        if (property != null) 
        { 
         object value = property.GetValue(user, null); 
         PropertyValueVariable = (value != null) ? value.ToString() : ""; 
        } 
        else 
        { 
         err = string.Format("no property found with the name \"{0}\"", UserProperty); 
        } 
       } 
       else 
       { 
        err = "__ActivationProperties.OriginatorUser was null"; 
       } 
      } 
      if (!string.IsNullOrEmpty(err)) 
       Common.LogExceptionToWorkflowHistory(new ArgumentOutOfRangeException(err), executionContext, 
                WorkflowInstanceId); 
     } 
     catch (Exception e) 
     { 
      Common.LogExceptionToWorkflowHistory(e, executionContext, WorkflowInstanceId); 
     } 

     return ActivityExecutionStatus.Closed; 
    } 
}

然后用以下.action接线起来xml文件：

<?xml version="1.0" encoding="utf-8"?> 
<WorkflowInfo Language="en-us"> 
<Actions> 
    <Action Name="Lookup initiator user property" 
ClassName="XXX.ActivityLibrary.LookupInitiatorInfo"

     <RuleDesigner Sentence="Lookup initating users property named %1 and store in %2"> 
      <FieldBind Field="UserProperty" DesignerType="TextArea" Id="1" Text="LoginName" />    
      <FieldBind Field="PropertyValueVariable" DesignerType="ParameterNames" Text="variable" Id="2"/> 
     </RuleDesigner> 
     <Parameters> 
      <Parameter Name="__Context" Type="Microsoft.Sharepoint.WorkflowActions.WorkflowContext, Microsoft.SharePoint.WorkflowActions" Direction="In"/>

     </Parameters> 
    </Action> 
</Actions> 
</WorkflowInfo>
