| Apr 29, 2016 at 19:25 | comment | added | Denis | We are doing exactly this, however double.parse will assume that your input is 100 % okay to be converted into double and if it's actually not the program will try to put some string value in an int variable thus throwing an exception. The TryParse is what we need it returns a boolean result whether if the operations succeeded or not. If it succeeds it also saves the value to specified by you variable (out x). So if we want to check how's the operation going we need to use the second method. | |
| Apr 29, 2016 at 18:29 | comment | added | Francis Jasmin | Hi Denis. When we check for correct user input. Why did you choose double.TryParse instead of double.Parse ? As i understand it, double.Parse can't be use with logic statement (like if and while). Well, why can't I tell the computer to use something like "While (we can't convert string to double (ak : !double.parse(string)))" do the following code. | |

| Apr 20, 2016 at 7:03 | comment | added | Denis | Correct we could have returned 'parse' and avoid converting | |

if TryParse() succeeds why do you return double.Parse(tempInput); in the SetNumber() method ?
