simple switch statement question

[suzy]

in vb6 you can do this:

select case value

case 1, 2
'do something

end case


how do you do this in c#?


thanks.

You can do:

switch(fish)
{
case onefish:
case twofish:
case redfish:
DoSomething();
break;
case bluefish:
DoSomethingElse();
break;
}

You need a break per case.

case onefish:
break;
case twofish:
break;
case redfish:
...

i know that, but what if i want to run the same bit of code for several
values of fish?

That's what Bob's code does! When fish is onefish, twofish, or
redfish, then DoSomething is called, when it is bluefish then
DoSomethingElse is called.

Maybe this will make it click:

switch (value)
{
case 1:
case 2:
DoSomething();
break;
}

This is what you asked using VB syntax.

Or maybe if you see it written this way:

switch(fish)
{
case onefish: case twofish: case redfish:
DoSomething();
break;
case bluefish:
DoSomethingElse();
break;
}

No you don't, Bern. Check the docs.

As per Bob's example, all three fishes call the same DoSomething:

case onefish:
case twofish:
case redfish:
DoSomething();
break;

Missing ellipses!

case onefish:
...
break;

Missing ellipses!

case onefish:
...
break;

Nothing is missing. Please read the following, paying special attention

No, I left out elipses indicating where extra lines of code would be ....

 

[Ravichandran J.V.]

Per case a break else there will be a "fallthrough" syndrome where
control will fulfill all the cases until it encounters a "break
statement, ellipses or no ellipses!
