Question

我试图在一行上结束2 if语句。

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

        If showing = True Then
            Do
                txtpassword.Text = ""
                If txtpassword.Text = password Then
                    My_Private_Screen.Show()
                    Me.Hide()
                    showing = False
                    attempts = 0
                ElseIf txtpassword.Text = "" Then
                    Do
                        If txtpassword.Text = password Then
                            My_Private_Screen.Show()
                            Me.Hide()
                        End If
                    Loop Until Inc = 5
                    Me.Hide()
                    showing = False
                    Do

                    Loop Until Inc2 = 300
                    Me.Show()
                    showing = True
                Else
                    MessageBox.Show("Incorrect Password")
                    attempts = attempts + 1
            Loop Until attempts = 5
            Me.Hide()
        End If

        showing = False

所以我需要知道如何结束2 ifs。我想知道如何做这样的事情：

        Me.Hide()
   End If
   End If

或者

 Me.Hide()
   End If End If

你需要在循环之前结束内部If。

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

    If showing = True Then
        Do
            txtpassword.Text = ""
            If txtpassword.Text = password Then
                My_Private_Screen.Show()
                Me.Hide()
                showing = False
                attempts = 0
            ElseIf txtpassword.Text = "" Then
                Do
                    If txtpassword.Text = password Then
                        My_Private_Screen.Show()
                        Me.Hide()
                    End If
                Loop Until Inc = 5
                Me.Hide()
                showing = False
                Do

                Loop Until Inc2 = 300
                Me.Show()
                showing = True
            Else
                MessageBox.Show("Incorrect Password")
                attempts = attempts + 1
            Endif
        Loop Until attempts = 5
        Me.Hide()
    End If

    showing = False
