body: <p>I have to deal to question: Filter all the Student in the list with Result is "Pass". But when I write a code like in the picture below, it always return wrong with caution like this: Cannot implicitly convert type 'string' to 'bool'. Although I used Convert.ToBoolean(t.Result) but it can't work?</p>
