about convert from string to int

[tony]

Hello!!


string number = "13";
int num;
Is it exactly the same if I use
num = Convert.ToInt32(number); OR
num = int.Parse(number)

Is it always in this case that I can choose whichever of int.Parse or
Convert.ToInt32 when I convert from a string containing numbers to an int.
So are these two interchangeable.

Convert.ToInt32 returns zero if string is null reference, when int.Parse
throws ArgumentNullException

string number = "13";
int num;
Is it exactly the same if I use
num = Convert.ToInt32(number); OR
num = int.Parse(number)

Is it always in this case that I can choose whichever of int.Parse or
Convert.ToInt32 when I convert from a string containing numbers to an int.

Hi,

Is it always in this case that I can choose whichever of int.Parse or
Convert.ToInt32 when I convert from a string containing numbers to an int.

Mostly, the difference is when the string is not a number as the other
posted said.

IIRC one of then use the other internally, This has been discussed here
several time, search in the archives to have more details , even a benchmark
of both.
