问题描述
我已经为此工作了很多时间，但是我仍然无法继续执行我的代码.
I've been working on this for quite a bit now but I still cannot get my code going.
我有一个名为Contact的类，该类具有只读属性Address. Address类具有类似Street和City的属性.现在，我要像这样分配联系人的街道:
I have a class called Contact which has a read-only property Address. The Address class has properties like Street and City. Now I want to assign a contact's street like this:
CallByName(contact, "Address.Street", CallType.Set, new_street)
但是我收到一条错误消息，说"Address.Street"不是Contact的成员.
But I am getting an error saying "Address.Street" is not a member of Contact.
我需要通过名称来设置属性
I need to set the property via its name so
contact.Adress.Street = new_street
不是一个选择.
如何使上面的第一个示例起作用?
How can I make the first example above work?
推荐答案
CallByName调用一个.你想做两个.
首先调用吸气剂:
Dim contactAddress As Address
Set contactAddress = CallByName(contact, "Address", CallType.Get)
然后，..那么没有理由让CallByName分配Street属性值:
Then, ..well then there's no reason to CallByName to assign the Street property value:
contactAddress.Street = new_street
