c# equivalent to select case true

[TS]

i used to do this in vb and haven't been able to in c# - any workaround?

Show us a code sample in VB what you want to do.

As a guess, you're not talking about the switch keyword, are you?

 

[Robbe Morris [C# MVP]]

switch(myvariable)
{
case "blah":
return;
default:
return false;
}

switch (true)
{
case 1:
break;
default:
break;

}

In VB, you are able to do this since the case statements can include a wide
range of expressions. In C#, the case expressions must be constant, so the
usefulness of this technique is greatly reduced.

thanks, yes i am looking for a
switch(true)
{
case var1 = 5 : ...
case var9 = 21: ...

i guess you can't do it as i thought

No, you can't do this in C#. Other languages have this kind of switch
construct:

switch (value)
{
case expression:
case expression:
...
default:
}

C# (as well as C, C++, and Java) has this kind of switch construct:

switch (expression)
{
case constant:
case constant:
case constant:
...
default:
}

So, no. You have to use if... else if... else if... else.

you can:
the c# equivalent is:

if (var1 == 5)
{
.....
}
else if (var9 == 21)
{
......
}
........
