Question

I know that trying to convert string “0” to boolean will fail, I also know how to fix this, thanks to Jon Skeets answers on other questions.

What I would like to know is WHY does C# not recognize “0” as a valid input for a boolean conversion, surely you could look at it like 0 = false, 1 = true, or even -1 = false and 0 = true, anyways, my logic tells me that it could be a valid input, so is there a very good reason why its not? My bet is old vb6 would be able to recognize the string input “0” as valid.

Answer 1

The simple answer is because that is the way the method is defined. However, in C# 0 does not evaluate to false, so it would be surprising if “0” were to be converted to false using Convert.
