int.TryPrase is great and all, but there is only one problem...it takes at least two lines of code to use:
int intValue; string stringValue = "123"; int.TryParse(stringValue, out intValue); .... Of course I can do something like:
string stringValue = "123"; int intValue = Convert.ToInt32(string.IsNullOrWhiteSpace(stringValue) ? 0 : stringValue); on just one line of code.
How can I perform some magic to get int.TryParse to use a one liner, or is there yet a third alternative out there?
Thanks!
Bezden answered the question best, but in reality I plan on using Reddogs solution.

TryParse(String, Int32) Converts the string representation of a number to its 32-bit signed integer equivalent. A return value indicates whether the conversion succeeded.
The Parse method returns the converted number; the TryParse method returns a boolean value that indicates whether the conversion succeeded, and returns the converted number in an out parameter. If the string isn't in a valid format, Parse throws an exception, but TryParse returns false .
Parse() method throws an exception if it cannot parse the value, whereas TryParse() method returns a bool indicating whether it succeeded. However, TryParse does not return the value, it returns a status code to indicate whether the parse succeeded and does not throw exception.
int intValue = int.TryParse(stringValue, out intValue) ? intValue : 0; If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
