switch statement in c#

[genc ymeri]

Hi,
I'm trying to do a very easy thing in SWITCH statment in C# but for some
reasons I can't do it (I'm getting errors messages,probab ly I'm missing
something)

What I want to do is this :

int n = aObject.Functio nOfIntergerType ;

switch (n)
{
case 1,2 : dothis; // <- how can I group multiple values in one case
?????
case 3 :dotThat;
}

Thank You.

Hi,

You can't have multiple case statements like that in C#.
However, in simple cases like that you can allow a fallthrough to the next statement.

switch(n)
{
case 1:
case 2:
dothis;
break;
case 3:
dothat;
break;
}

A fallthrough is only allowed if the case is empty.

Hi Genc,

You can do a fall through like what Morten recommended or you can use goto
statement in you swicth statements :)

case 1:
goto case 3;
case 2:
Console.WriteLi ne("OOps");
break;
case 3:
Console.WriteLi ne("Nah");
break;
default:
Console.WriteLi ne("Wrong");
break;

Have fun!
