你是什么试图添加到列表框? 像"rkimble:这是我的评论"这样的字符串或者单词列表?


如果你只想要字符串,那就是:


ListBox1.Items.Add (TextBox1.Text&":"& RichTextBox1.Text)


如果这不是你想要的,你能否让我们更好地了解应该是什么在列表框中?

What are you trying to add to the listbox?  A string like "rkimble:This is my comment" or a list of words?

If you just want the string it would be:

ListBox1.Items.Add(TextBox1.Text & ":" & RichTextBox1.Text)

If that's not what you want, can you give us a better idea of what should be in the listbox?
