推荐答案

不要；不要使用For Each ...

Don;t use For Each...

For index As Integer = 0 To 1
    Dim objAddress As CRAddressDetails = AddressList(index)
    ...
Next

AddressList是哪种类型?
CRAddressDetails []?数组列表?列出< craddressdetails> ;?字典?

在foreach循环之外，您可以编写:

what kind for AddressList?
CRAddressDetails[]? ArrayList? List<craddressdetails>? Dictionary?

outside foreach cycle you can write:

Dim zeroindex as CRAddressDetails = AddressList(0)
For Each objAddress As CRAddressDetails In AddressList 
 
    //here you can use zeroindex 

next
