Vb.net 更改给定文本框中句子的顺序

我考虑过决心，但我不知道怎么做

例如，我在文本框的每一行都有一些句子

Sentence 1
Sentence 2
Sentence 3

我希望输出“混合/随机”如下：

Sentence 3
Sentence 1
Sentence 2

有什么想法吗？我对编程不太在行。

您可以使用Linq的扩展方法来完成这项任务

    '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

    Next

是的，看看字符串类；也许是弦，分开。然后是随机类。尝试一些代码，如果你有一个特定的问题，张贴你的代码和问题。
