The int.ToString(string) method formats an int value in a specified format by using a System.Globalization.NumberFormatInfo object that represents the conventions of the current culture. If you want to use the default ("G", or general) format or specify a different culture, use the other overloads of the int.ToString(string) method, as follows:

The format parameter can be any valid standard numeric format specifier except for "R", as well as any combination of custom numeric format specifiers. If format is null or an empty string (""), the return value of this instance is formatted with the general numeric format specifier ("G").

The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

• For more information about numeric format specifiers, see Standard Numeric Format Strings and Custom Numeric Format Strings.

• For more information about formatting, see Formatting Types.

The return value of this instance is formatted with the System.Globalization.NumberFormatInfo for the current culture.

This example demonstrates converting a int to a string.

using System;
public class Int32ToStringExample {
   public static void Main() {
      Int32 i = 32;
      Console.WriteLine(i);
      String[] formats = {"c", "d", "e", "f", "g", "n", "p", "x" };
      foreach(String str in formats)
         Console.WriteLine("{0}: {1}", str, i.ToString(str));
   }
}

The output is
