No, but you can use (at least in Java)

不,但你可以使用(至少在Java中)

switch (temp) {
    case "NW":
    case "New":
       temp="new stuff";
       break;
}

Yes. This is how it is done.

是。这就是它的完成方式。

switch (temp)
{
   case "NW":
   case "New":
     temp = "new stuff"
     break;
}

Actually, I answered this very same question before.

实际上,我之前回答了同样的问题。

Try

switch (temp)
{
case "NW":
case "New":
temp = "new stuff"
break;
}

Assuming C#, you want:

假设C#,你想要:

switch(temp)
{
    case "NW":
    case "New":
        temp = "new stuff";
        break;
}

#5

switch (temp) {
    case "NW":
    case "New":
        temp = "new stuff"
        break;
    default:
        Console.WriteLine("Hello, World!");
        break;
}

I know you asked about C#, and have good answers there, but just for perspective (and for anyone else reading that might find it useful), here's the VB answer:

我知道你问过C#,并且在那里有很好的答案,但只是为了透视(对于其他任何阅读可能会觉得有用的人),这是VB的答案:

Select Case temp
  Case "NW", "New"
    temp = "new stuff"
  Case Else
    'something else...
End Select

Notice that there's no "break"--VB does not drop through cases. On the other hand, you can have multiple match conditions on a single case.

请注意,没有“中断” - VB不会丢失案例。另一方面,您可以在一个案例中拥有多个匹配条件。

Be care you DON'T do this

小心你不要这样做

...
  Case "NW" Or "New"
...

What you have there is a single condition with a bitwise Or between the two terms....

你在那里有一个单一的条件,在两个术语之间有一个按位或......
