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

Default ("G") format	Default (current) culture	int.ToString
A specific format	Default (current) culture	int.ToString(string)
A specific format	A specific culture	int.ToString(string, IFormatProvider)

The provider parameter is an object that implements the IFormatProvider interface. Its IFormatProvider.GetFormat(Type) method returns a System.Globalization.NumberFormatInfo object that provides culture-specific information about the format of the string that is returned by this method. The object that implements IFormatProvider can be any of the following:

• A System.Globalization.CultureInfo object that represents the culture whose formatting rules are to be used.

• A System.Globalization.NumberFormatInfo object that contains specific numeric formatting information for this value.

• A custom object that implements IFormatProvider and whose IFormatProvider.GetFormat(Type) method returns a System.Globalization.NumberFormatInfo object that provides formatting information.

If provider is null or a System.Globalization.NumberFormatInfo object cannot be obtained from provider, the return value is formatted using the System.Globalization.NumberFormatInfo object for the thread current culture. For information about the thread current culture, see System.Threading.Thread.CurrentCulture.

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