The ToString(String, IFormatProvider) method formats a Double value in a specified format of a specified culture. If you want to use default format or culture settings, use the other overloads of the ToString method, as follows:

To use format

For culture

Use the overload

Default ("G") format

Default (current) culture

ToString()

Default ("G") format

A specific culture

ToString(IFormatProvider)

A specific format

Default (current) culture

ToString(String)

The format parameter can be any valid standard numeric format specifier except for D, R, and X, as well as any combination of custom numeric format specifiers. If format is nullptr or an empty string, the return value for 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:

The provider parameter is an IFormatProvider implementation whose IFormatProvider::GetFormat method returns a NumberFormatInfo object. Typically, provider is a NumberFormatInfo or CultureInfo object. The provider parameter supplies culture-specific information used in formatting. If provider is nullptr, the thread current culture is used.

The following example displays a Decimal value using each of the supported standard numeric format specifiers for several different cultures.
