主题：数组个数问题

Dim Names(3) As String
Names (0) = "杨国辉"
Names (1) = "柯迎"
Names (2) = "陈绍月"
Names (3) = "朱志欣"
Dim name As String
    For  i As Integer  = 0 To names.Length-1
    
        name = name & "," & names(i)
        Next
Output.Show(name.Trim(",") )

Dim  na() As  String
    na = name.Split(",")
Output.show(na.length)

变成5个!

请教下   为什么  数组 转化为 一串文本   然后再转化为 数组  会出现 个数不一样!
