Question

我想知道在文本框中打印文本时如何使用arraylist存储不同的字符串并使用字符串。

我很感激anyhelp

我已经这样做了，无论如何打印不同的单词，因为它只在所有文本框上打印“Apple”。另外我如何使用文本框从userinnput在arraylist上存储字符串？

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    For Each x As TextBox In mk
        x.Text = "Apple"


    Next
End Sub

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    mk.Add(TextBox1)
    mk.Add(TextBox2)
    mk.Add(TextBox3)
    mk.Add(TextBox4)

End Sub

如果要在每个文本框中存储不同的字符串，则无法使用循环。例如，你有这个：

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    For Each x As TextBox In mk
        x.Text = "Apple"


    Next
End Sub

但是你需要这样的东西：

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Textbox1.Text = "Apple"
    Textbox2.Text = "Banana"
    Textbox3.Text = "Pear"
    Textbox4.Text = "Strawberry"
End Sub

如果要将文本存储在每个文本框中而不是文本框中，可以执行以下操作：

Private Sub Form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
    mk.Add(TextBox1.Text)
    mk.Add(TextBox2.Text)
    mk.Add(TextBox3.Text)
    mk.Add(TextBox4.Text)
End Sub
