At least you could be 100% sure you would not get orders of magnitude downgrade of a generic sprintf. In practice people don't sprintf const ints and the itoa above is nearly as optimized as it gets. public string ToString (string format, IFormatProvider provider); [] override this.ToString : string * IFormatProvider -> string override this.ToString : string * IFormatProvider -> string I was developing iota c language client APIs in the past few days. When I was writing unit test of the APIs I found the need of converting integer into string. But, it is a non standard function. Set the integer for which you want the string − int num = 299; Use the ToString() method to convert Integer to String − Compared with C strings, in addition to the advantage of unlimited length, there are many other convenient functions. char * itoa ( int value, char * str, int base ); “stdlib.h” header file supports all the type casting functions in C language. In the examples of this tutorial, we build string messages that contains an integer. One, string String is a string type provided by C++. The format used is the same that printf would print for the corresponding type: To convert an integer to string in C#, use the ToString() method. The provider parameter is an object that implements the IFormatProvider interface.
