推荐答案

你的代码不是为我构建的 - 这可能是因为在你的 MessageBox.Show 中:

Your code didn't build for me - it's probably because in your MessageBox.Show:

MessageBox.Show(intFah.ToString & ControlChars.CrLf & "Would you like to start another temp conversion?", MessageBoxButtons.YesNo)

您没有传递正确数量的参数.根据链接，它需要文本、标题(标题)和按钮选项

You aren't passing the right number of parameters. As per the link, it needs the text, a caption (title) and then the button options

如果我把它改成:

MessageBox.Show(intFah.ToString & ControlChars.CrLf & "Would you like to start another temp conversion?", "A Caption", MessageBoxButtons.YesNo)

然后它会构建，当我运行应用程序时，我可以根据您要查找的内容将答案显示在一行中，将文本显示在第二行中.

Then it builds and when I run the app I can get the answer appearing in one line and the text on a second line as per what you're looking for.
