如何创建具有属性的笔记"ReminderTime"

Question

我想创建一个带提醒的便条，这是我的代码：

'Create a note locally.
Dim myNote As New Note()

myNote.Title = "Sample note with Reminder set"
myNote.Content = "Hello, world - this note has a Reminder on it."
myNote.Attributes.ReminderTime = DateTime.Now.ToEdamTimestamp()

'Create the note in the service, in the user's personal, default notebook.
Dim store As ENNoteStoreClient =ENSessionAdvanced.SharedSession.PrimaryNoteStore
Dim resultNote As Note = store.CreateNote(myNote)

但是没用。错误代码：

myNote.Attributes.ReminderTime = DateTime.Now.ToEdamTimestamp()

笔记的属性是一个NoteAttributes对象，所以你必须先创建对象：

'Create a note locally.
Dim myNote As New Note()

myNote.Title = "Sample note with Reminder set"
myNote.Content = "Hello, world - this note has a Reminder on it."

'Create the note's attributes.
Dim myNoteAttributes As New NoteAttributes

myNoteAttributes.ReminderTime = DateTime.Now.ToEdamTimestamp()
myNote.Attributes = myNoteAttributes    

'Create the note in the service, in the user's personal, default notebook.
Dim store As ENNoteStoreClient =ENSessionAdvanced.SharedSession.PrimaryNoteStore
Dim resultNote As Note = store.CreateNote(myNote)
