Vb.net 如何创建具有属性的便笺；“提醒时间”；

我想创建一个带有提醒的便笺，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)

但它不起作用。错误代码：

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

详情如下：

未处理System.NullReferenceException HResult=-2147467261 信息=未将对象引用设置到对象的实例。

注释的属性是

NoteAttributes

对象，因此必须首先创建对象：

'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)

抱歉，我不明白您的意思。请您再详细解释一下好吗？

myNote.Attributes

可能为空是的，它工作得很好，谢谢。我在哪里可以找到这样的教程？很遗憾，没有任何适用于Evernote Windows SDK的教程。但是如果需要的话，你可以在这里问更多的问题。而且，因为我的答案对你很有用，如果你能把我的答案确定为公认的答案，那就太好了。谢谢！
