Is it legal and possible to access the return value in a finally block?

Question

I wish to set a usererror string before leaving a function, depending on the return code and variable in the function.

I currently have:

Dim RetVal as RetType

try
...
if ... then
    RetVal = RetType.FailedParse
    end try
endif
...

finally
    select case RetVal
        case ...
            UserStr = ...
    end select
end try

return RetVal

Is it possible to use return RetType.FailedParse, then access this in the finally block?

Answer 1

The only real way of doing this in C# would be to declare a variable at the start of the method to hold the value - i.e.

SomeType result = default(SomeType); // for "definite assignment"
try {
   // ...
   return result;
}
finally {
    // inspect "result"
}

In VB, you might be able to access the result directly - since IIRC it kinda works like the above (with the method name as "result") anyway. Caveat: I'm really not a VB person...
