Use
用
str.Split(ControlChars.CrLf.ToCharArray(), StringSplitOptions.RemoveEmptyEntries)
instead.
反而。

The given answer splits on any crOR lfand removes blanks; that works ok for the given case, but it would remove 'real' empty lines as well (and feels unclean to me).
给定的答案在任何crOR上拆分lf并删除空格；这适用于给定的情况，但它也会删除“真正的”空行（并且对我来说感觉不干净）。
Alternative:
选择：
System.Text.RegularExpressions.Regex.Split(str, vbCrLf)
(note that the second string is a regex-pattern, special chars would have to be escaped)
（请注意，第二个字符串是正则表达式模式，必须转义特殊字符）

This code will split on line-feed, new line or both(vbCrLf). It will not remove empty lines.
此代码将在换行、换行或两者（vbCrLf）上拆分。它不会删除空行。
Dim arr() As String = System.Text.RegularExpressions.Regex.Split(text, "(\r\n|\r|\n)", _
RegularExpressions.RegexOptions.ExplicitCapture)
