UInt64.ToString Method

Updated: September 2009

Converts the numeric value of this instance to its equivalent string representation.

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

public override string ToString()

Return Value

Type: System.String
The string representation of the value of this instance, consisting of a sequence of digits ranging from 0 to 9, without a sign or leading zeroes.

The return value is formatted with the general numeric format specifier ("G") and the NumberFormatInfo object for the current culture. The string representation of the UInt64 value consists of a sequence of digits ranging from 0 to 9 without leading zeros.

To define the formatting of the 64-bit unsigned integer value's string representation, call the ToString(String) method.

The following example displays a UInt64 value by using the default ToString() method. It also displays the string representations of the UInt64 value that results from using some standard format specifiers. The examples are displayed using the formatting conventions of the en-US culture.

using System;

public class Example
{
   public static void Main()
   {
      ulong value = 163249057;
      // Display value using default ToString method.
      Console.WriteLine(value.ToString());      
      Console.WriteLine();

      // Define an array of format specifiers.
      string[] formats = { "G", "C", "D", "F", "N", "X" };
      // Display value using the standard format specifiers. 
      foreach (string format in formats)
         Console.WriteLine("{0} format specifier: {1,16}", 
                           format, value.ToString(format));         
   }
}
// The example displays the following output: 
//       163249057 
//        
//       G format specifier:        163249057 
//       C format specifier:  $163,249,057.00 
//       D format specifier:        163249057 
//       F format specifier:     163249057.00 
//       N format specifier:   163,249,057.00 
//       X format specifier:          9BAFBA1
