Assembly: mscorlib (in mscorlib.dll)
Parameters
- provider
-
Type:
System.IFormatProvider
An object that supplies culture-specific formatting information.
Return Value

Implements
IConvertible.ToString(IFormatProvider)The ToString(IFormatProvider) method formats an Int32 value in the default ("G", or general) format by using the NumberFormatInfo object of a specified culture. If you want to specify a different format or the current culture, use the other overloads of the ToString method, as follows:
To use format | For culture | Use the overload |
|---|---|---|
Default ("G") format | Default (current) culture | |
A specific format | Default (current) culture | |
A specific format | A specific culture |
The provider parameter is an object that implements the IFormatProvider interface. Its GetFormat method returns a 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 CultureInfo object that represents the culture whose formatting rules are to be used.
A NumberFormatInfo object that contains specific numeric formatting information for this value.
A custom object that implements IFormatProvider and whose GetFormat method returns a NumberFormatInfo object that provides formatting information.
If provider is null or a NumberFormatInfo object cannot be obtained from provider, the return value is formatted using the NumberFormatInfo object for the thread current culture. For information about the thread current culture, see Thread.CurrentCulture.
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 in the .NET Framework.
The following example displays the string representation of an Int32 value using CultureInfo objects that represent several different cultures.
int value = -16325; // Display value using the invariant culture. Console.WriteLine(value.ToString(CultureInfo.InvariantCulture)); // Display value using the en-GB culture. Console.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("en-GB"))); // Display value using the de-DE culture. Console.WriteLine(value.ToString(CultureInfo.CreateSpecificCulture("de-DE"))); // This example displays the following output to the console: // -16325 // -16325 // -16325
