value of 1 dimensional array of string cannot be converted to String
提问by NIMISH DESHPANDE
I am trying to assign values of array to a string, following is the code:
我正在尝试将数组的值分配给一个字符串，以下是代码：
oDocument1.IdentifierCode = lstFundIdentifiers.ToArray()
where IdentifierCode is a string while lstFundIdentifiers is declared as
其中 IdentifierCode 是一个字符串，而 lstFundIdentifiers 被声明为
ByVal lstFundIdentifiers As List(Of String).
ByVal lstFundIdentifiers As List(Of String).
I am not sure as to what is going wrong.
我不确定出了什么问题。

String <> String()
字符串 <> 字符串()
Trying to assign an array to a string is like trying to put 4 tires on a unicycle. An array (or list) is a collection of objects, in your case, strings.
尝试将数组分配给字符串就像尝试将 4 个轮胎放在独轮车上。数组（或列表）是对象的集合，在您的情况下是字符串。
You can do this: yourArray(1) = yourStringor yourString = yourArray(0), but you can't do this: yourString = yourArray.
你可以这样做：yourArray(1) = yourString或yourString = yourArray(0)，但你不能这样做：yourString = yourArray。
EDIT in response to your comment:
编辑以回应您的评论：
"So previously it was something like this oDocument.FundServCodes = lstFundServCodes.ToArray()"
“所以以前它是这样的 oDocument.FundServCodes = lstFundServCodes.ToArray()”
FundServCodes is an array itself, which is why that would work. You can easily confirm this by going to the class and looking at the FundServCodes property.
FundServCodes 本身就是一个数组，这就是为什么它会起作用。您可以通过转到该类并查看 FundServCodes 属性来轻松确认这一点。

These are basic programming concepts. Maybe you should go read up on collections, data types, objects, etc. There are 1000's of programming books and tutorials for all skill levels out there. Look one up and go through it.
