'||' operators to be used between two enums in a switch statement

I want to check if a function returns either of two enum values, each of the same enumeration type.

For simplicity's sake, I attempted to create a case as follows:

case EnumerationTypeExample.TypeA || EnumerationTypeExample.TypeB:

Unfortunately, this does not please C#, which says I cannot use an '||' operator despite them being of the same type; strange. Might there be a way this could be done otherwise? An if statement perhaps might work and I may retreat to that, however, I would much rather use a switch statement if possible.

Solution

  • A case statement must be constants, not a computation. However you can use fall through in this case:

    switch (something)
{
    case EnumerationTypeExample.TypeA:
    case EnumerationTypeExample.TypeB:
    {
        DoSomething();   
        break;  
    }
}

    Now the code will run in both situations.
