什么是带有 case OR-ing 的 VB.NET select case 语句逻辑? [英] What is the VB.NET select case statement logic with case OR-ing?

问题描述

我在 case 表达式中使用了 Or 语句.

I'm using an Or statement in my case expression.

即使我有一个在这个范围内的值，它也没有找到匹配项.为什么不呢?

Even though I have a value within this range, it didn't find a match. Why not?

示例代码:

Select Case 2
    Case 0
        ' Some logic

    Case 1
        ' Some other logic

    Case 2 Or 3
        Console.WriteLine("hit")

 End Select

根据上述内容，我假设 hit 会被打印出来，但事实并非如此.

With the above I would assume that hit would be printed, but that's not the case.

推荐答案

使用逗号运算符分隔 case 语句

Use the comma operator to delimit case statements

Select Case 2
    Case 0,1,2,3
        Console.WriteLine("hit")
 End Select
