在子例程中退出 Select Case

Question

我有一个问题，

在我的主要标签中，我的函数/子例程一旦完成就会相互跟随。然后我的第三个子例程之一包含一个选择案例，对于输入 5 我希望它继续到下一个子例程，但是我不确定如何执行此操作。

Sub Main()

    Task723()
    Task724()
    Task731()

End Sub

Sub Task723()
    Dim x0 = -20 ' Initial values assumed
    Dim ch As Integer
    ch = 5
    While ch <> 0
Line2:
        Console.WriteLine(vbLf & "(1)option1"
        Console.WriteLine(vbLf & "(2)option2")
        Console.WriteLine(vbLf & "(3)option3")
        Console.WriteLine(vbLf & "(4)option4")
        Console.WriteLine(vbLf & "(5)to go next")
        Console.Write(vbLf & "Enter Your Choice :")
        ch = Integer.Parse(Console.ReadLine())
        Select Case ch
            Case 1
                option1(x0)
                Console.WriteLine(vbLf & "Press Any Key To Continue...")
                Console.ReadLine()
                Console.Clear()
            Case 2
                option2(x0)
                Console.WriteLine(vbLf & "Press Any Key To Continue...")
                Console.ReadLine()
                Console.Clear()
            Case 3
                option3(x0)
                Console.WriteLine(vbLf & "Press Any Key To Continue...")
                Console.ReadLine()
                Console.Clear()
            Case 4
                option4(x0)
                Console.WriteLine(vbLf & "Press Any Key To Continue...")
                Console.ReadLine()
                Console.Clear()
            Case 5
                Console.Clear()
                GoTo Line4

            Case Else
                Console.Clear()
                Console.WriteLine(vbLf & "Invalid Input, Please Try Again")
                GoTo Line2


        End Select
Line4:
    End While
End Sub

Answer 1

您只想将ch 设置为0 并退出后续While ch <> 0 检查

            Case 5
                Console.Clear()
                ch = 0

顺便说一句，你不需要Line2: 和Line4: 以及GoTo Line2 和GoTo Line4
