Convert.ToString Method (Int64, IFormatProvider)
Converts the value of the specified 64-bit signed integer to its equivalent string representation, using the specified culture-specific formatting information.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- value
- Type: System.Int64
The 64-bit signed integer to convert.
- provider
- Type: System.IFormatProvider
An object that supplies culture-specific formatting information.
This implementation is identical to Int64.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(Int64, IFormatProvider) method to convert each element in a long integer array to its equivalent string representation. The conversion uses the invariant culture as well as the custom NumberFormatInfo object.
long[] numbers = { ((long) Int32.MinValue) * 2, ((long) Int32.MaxValue) * 2}; System.Globalization.NumberFormatInfo nfi = new System.Globalization.NumberFormatInfo(); nfi.NegativeSign = "~"; nfi.PositiveSign = "!"; foreach (long 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: // -4294967296 --> ~4294967296 // 4294967294 --> 4294967294
