Vb.net messagebox.show出现问题

我在messagebox.show上遇到了问题。我希望答案和这一行“您想尝试另一个温度转换吗？”出现在带有yesno按钮的消息框中

Public Class Form1
    Dim intFah As Windows.Forms.DialogResult

    Private Sub BtnFah_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnFah.Click
        Try
            Dim intFah As Integer

            intFah = CInt(TxtBoxTemp.Text)
            intFah = (intFah * 9) / 5 - 32
            MessageBox.Show(intFah.ToString & ControlChars.CrLf & "Would you like to start another temp conversion?", MessageBoxButtons.YesNo)
        Catch
            MessageBox.Show("Would you like to start another temp conversion?", "System Error", MessageBoxButtons.YesNo)

        End Try
    End Sub
End Class

您的代码不是为我生成的-可能是因为在您的MessageBox中。显示：

Public Class Form1
    Dim intFah As Windows.Forms.DialogResult

    Private Sub BtnFah_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnFah.Click
        Try
            Dim intFah As Integer

            intFah = CInt(TxtBoxTemp.Text)
            intFah = (intFah * 9) / 5 - 32
            MessageBox.Show(intFah.ToString & ControlChars.CrLf & "Would you like to start another temp conversion?", MessageBoxButtons.YesNo)
        Catch
            MessageBox.Show("Would you like to start another temp conversion?", "System Error", MessageBoxButtons.YesNo)

        End Try
    End Sub
End Class

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

你没有通过正确数量的考试。根据链接，它需要文本、标题，然后是按钮选项

Public Class Form1
    Dim intFah As Windows.Forms.DialogResult

    Private Sub BtnFah_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnFah.Click
        Try
            Dim intFah As Integer

            intFah = CInt(TxtBoxTemp.Text)
            intFah = (intFah * 9) / 5 - 32
            MessageBox.Show(intFah.ToString & ControlChars.CrLf & "Would you like to start another temp conversion?", MessageBoxButtons.YesNo)
        Catch
            MessageBox.Show("Would you like to start another temp conversion?", "System Error", MessageBoxButtons.YesNo)

        End Try
    End Sub
End Class

如果我将其更改为：

Public Class Form1
    Dim intFah As Windows.Forms.DialogResult

    Private Sub BtnFah_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnFah.Click
        Try
            Dim intFah As Integer

            intFah = CInt(TxtBoxTemp.Text)
            intFah = (intFah * 9) / 5 - 32
            MessageBox.Show(intFah.ToString & ControlChars.CrLf & "Would you like to start another temp conversion?", MessageBoxButtons.YesNo)
        Catch
            MessageBox.Show("Would you like to start another temp conversion?", "System Error", MessageBoxButtons.YesNo)

        End Try
    End Sub
End Class

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

然后它会生成，当我运行应用程序时，我可以得到答案，答案显示在一行中，文本显示在第二行中，与您所寻找的内容一致。

使用返回值。谢谢！它正在工作。现在我只需要确保消息框上的按钮正常工作。

Public Class Form1
    Dim intFah As Windows.Forms.DialogResult

    Private Sub BtnFah_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnFah.Click
        Try
            Dim intFah As Integer

            intFah = CInt(TxtBoxTemp.Text)
            intFah = (intFah * 9) / 5 - 32
            MessageBox.Show(intFah.ToString & ControlChars.CrLf & "Would you like to start another temp conversion?", MessageBoxButtons.YesNo)
        Catch
            MessageBox.Show("Would you like to start another temp conversion?", "System Error", MessageBoxButtons.YesNo)

        End Try
    End Sub
End Class
