我虽然关于解决方案,但我不知道怎么做。
例如,我在文本框中的每一行都有一些句子。
Sentence 1
Sentence 2
Sentence 3
我想要输出"混合/ randomed"类似的东西:
Sentence 3
Sentence 1
Sentence 2
有什么想法吗?我编程不好。

你可以使用Linq的OrderBy扩展方法来实现这一目的。
'Setup
Dim txtYourTextBox As New TextBox
txtYourTextBox.Text = "Sentence 1" & ControlChars.NewLine & "Sentence 2" & ControlChars.NewLine & "Sentence 3"
'Creates random numbers.
Dim rnd As New System.Random()
'Get the list of sentences randomized.
Dim lstRandomizedSentences As List(Of String) = txtYourTextBox.Text.Split(ControlChars.NewLine).OrderBy(Function() rnd.Next).ToList()
'Clear the textbox before repopulating with randomized sentences.
txtYourTextBox.Text = String.Empty
'Loop through all of your randomized sentences to populate the textbox.
For Each strSentence In lstRandomizedSentences
'.Trim() so extra line breaks aren't added.
txtYourTextBox.Text += strSentence.Trim() & ControlChars.NewLine
