The easiest way is to convert it to a List and then add.
最简单的方法是将其转换为List，然后添加。
Dim a As List(Of String) = ("One,Two").Split(",").ToList
a.Add("Three")
or if you really want to keep an array.
或者如果你真的想保留一个数组。
Dim a As String() = ("One,Two").Split(",")
Dim b as List(Of String) = a.ToList
b.Add("Three")
a=b.ToArray
And here is something really outside the box:
这里有一些真正开箱即用的东西：
a = (String.Join(",", a) & ",Three").Split(",")

For a different approach, try:
对于不同的方法，请尝试：
Dim a As String() = ("One,Two").Split(CChar(","))
Debug.Print(CStr(UBound(a)))
ReDim Preserve a(9)
Debug.Print(CStr(UBound(a)))
The output to the immediate window is:
立即窗口的输出是：
1
9
Note: I have had to slightly change your original line because I always use Option Strict Onwhich does not permit implicit conversions.
注意：我不得不稍微更改您的原始行，因为我总是使用Option Strict On不允许隐式转换的内容。
