string test = "true"; bool test2 = (test.ToLower() == "true"); Since there is no Convert.ToBoolean, what is the solution?

Found these but their not exactly perfect either:

bool.TrueString.Equals("true")

or this:

true.ToString().Equals("true")

Thank you for your reply. But I think both of those will always give me a true and they can't help evaluate a string type variable.

Could define your own "convert to boolean" method:

        public static bool ToBoolean(string str)
        {
            if (str == bool.TrueString)
            {
                return true;
            }
            
            if (str == bool.FalseString)
            {
                return false;
            }

            throw new InvalidOperationException("String was not a bool");
        }

string test = "true";

bool test2 = (test.ToLower() == "true");

Since there is no Convert.ToBoolean, what is the solution?

Is there a bool.Parse() method?

            }

            throw new InvalidOperationException("String was not a bool");
        }

There is a StackOverflow article that is worth reading about 'Why does Boolean.ToString output “True” and not “true”'. Great discussion.

For what I understood, the string has to be "True" and "False", and "true" and "false" are not valid.

Yes they will but I meant for you to replace the literal string "true" with the string variable you wish to test. Using your nomenclature it becomes like so:

string test = "true";

bool test2 = bool.TrueString.Equals(test);
