如果我已经阅读了您的正确发出，并且连接的字符串保存在
nav2.Value，那么您只需要根据使用的串联值进行拆分即可.

If I have read your issue correctly and the concatenated strings are held in
nav2.Value then you just need to do a split based on whatever concatenation value you have used

char seperator = '_'; // whatever you use to indicate the concatenation
string[] items = nav2.Value.Split(seperator);

//you should then have the values stored in
items[0]
items[1]
items[2]

嗨
您可以通过GetAttribute方法访问属性值吗?
nav2.GetAttribute("FirstName"，"URI")

Hi
You can access attribute values through GetAttribute method right?
nav2.GetAttribute("FirstName", "URI")
