在下面的代码中怎么样可以把 public string Load(string id, object inputs = null,Dictionary<string,object> ids=null)
中的 ids传到工流中??

public WFHelp()
{
this.bookMark = "BookmarkName";

this.connectionString = System.Configuration.ConfigurationManager.AppSettings["ConnectionString"];
}
public WFHelp(string bookMark, string path, string connectionString)
{
this.bookMark = bookMark;
this.path = path;
this.connectionString = connectionString;
}

public string Load(string id, object inputs = null,Dictionary<string,object> ids=null)
{
_instanceStore = new SqlWorkflowInstanceStore(connectionString);
InstanceView view = _instanceStore.Execute
(_instanceStore.CreateInstanceHandle(),
new CreateWorkflowOwnerCommand(),
TimeSpan.FromSeconds(30));
_instanceStore.DefaultInstanceOwner = view.InstanceOwner;
WorkflowApplication i = new WorkflowApplication(ActivityXamlServices.Load(path));
i.InstanceStore = _instanceStore;
i.PersistableIdle = (waiea) => PersistableIdleAction.Unload;
try
{
i.Load(new Guid(id));
return i.ResumeBookmark(bookMark, inputs).GetString();
}
catch (Exception ex)
{
throw ex;
}
}

public string Create(IDictionary<string, object> parameters)

return i.Id.ToString();
}
}
}
