getting message condition is always true

问题

I'm getting message from resharper as condition is always true for following code

if (filters == "answers" || "solution") {

}

what's happening here in this code?

回答1:

if (filters == "answers" || "solution") {

}

In the above code "solution" is true always

So, Change to this

  if (filters == "answers" || filters =="solution") {

    }

Example

If("i")
{

}

Above is true always.

So, In your code the second condition returns TRUE always

As per the Boolean OR , [Anything with TRUE] is always TRUE

You have two predicates , So your truth table will be

   i/p               o/p
TRUE   FALSE        True
FALSE  TURE         True
FALSE  FALSE         False
TRUE   TRUE         True

in your code, You will never get the condition #1 and #3 so, It will be true always

so your code will be true always
