Convert.ToString Method (Int32, IFormatProvider)

Converts the value of the specified 32-bit signed integer to its equivalent string representation, using the specified culture-specific formatting information.

Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static string ToString(
	int value,
	IFormatProvider provider
)

Parameters

value
Type: System.Int32

The 32-bit signed integer to convert.

provider
Type: System.IFormatProvider

An object that supplies culture-specific formatting information.

Return Value

Type: System.String
The string representation of value.

This implementation is identical to Int32.ToString(IFormatProvider).

The following example defines a custom NumberFormatInfo class that defines its negative sign as the string "~" and its positive sign as the string "!". It then calls the ToString(Int32, IFormatProvider) method to convert each element in an array of integers to its equivalent string representation. The conversion uses the invariant culture as well as the custom NumberFormatInfo object.

int[] numbers = { Int32.MinValue, Int32.MaxValue};
System.Globalization.NumberFormatInfo nfi = new System.Globalization.NumberFormatInfo();
nfi.NegativeSign = "~";
nfi.PositiveSign = "!";

foreach (int number in numbers)
   Console.WriteLine("{0,-12}  -->  {1,12}", 
                     Convert.ToString(number, System.Globalization.CultureInfo.InvariantCulture), 
                     Convert.ToString(number, nfi));
// The example displays the following output: 
//       -2147483648  -->  ~2147483648 
//       2147483647  -->  2147483647
