Question

Is there any significant advantages for converting a string to an integer value between int.Parse() and Convert.ToInt32() ?

string stringInt = '01234';  int iParse = int.Parse(stringInt);  int iConvert = Convert.ToInt32(stringInt); 

I found a question asking about casting vs Convert but I think this is different, right?

Answer 1

When passed a string as a parameter, Convert.ToInt32 calls int.Parse internally. So the only difference is an additional null check.

Here’s the code from .NET Reflector

public static int ToInt32(string value) {     if (value == null)     {         return 0;     }     return int.Parse(value, CultureInfo.CurrentCulture); }
