_itoa_s equivalent in c#

Hi,
Could some one please let me know what is the  c# equal of  _itoa_s   ,
I am in the middle of converting some c++ codes in to c# but I don't understand the usage of   _itoa_s  


har fif_ret;
char buffer[50];
CString strPlace;
strPlace = "2";
place = atoi(strPlace.GetBuffer(0));
_itoa_s(fif_ret, buffer, 2);

also  what would be the output of   fif_ret  ?

_itoa_s  is integer to a string ...
so, basically, you use

int yourint = 123:
string yourstring = yourint.ToString();

that's it, in short.
for special needs (formatting of the thousand separator, or comma for decimals), you can use the 2nd optional argument of the ToString() function, which either allows to specify a formatting string or a FormatProvider

As a general point you should look it up in the help files.  Just converting something you don't understand means: I guess it is this so I'll put this in place and hope, if it doesn't work correctly afterwards then it isn't my problem.
