UInt64.ToString Method

Microsoft Silverlight will reach end of support after October 2021. Learn more.

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

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

Syntax

'Declaration
<SecuritySafeCriticalAttribute> _
Public Overrides Function ToString As String

[SecuritySafeCriticalAttribute]
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.

Remarks

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.

Note:
Because the UInt64 data type is not supported on the Macintosh OS X operating system, the string representation of a UInt64 value may be different from the string representations of other .NET Framework numeric types that are supported by OS X.

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

Examples

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.

Module Example
   Public Sub Demo(ByVal outputBlock As System.Windows.Controls.TextBlock)
      Dim value As ULong = 163249057
      ' Display value using default ToString method.
      outputBlock.Text &= value.ToString() & vbCrLf
      outputBlock.Text &= vbCrLf

      ' Define an array of format specifiers.
      Dim formats() As String = {"G", "C", "D", "F", "N", "X"}
      ' Display value using the standard format specifiers.
      For Each format As String In formats
         outputBlock.Text += String.Format("{0} format specifier: {1,16}", _
                           format, value.ToString(format)) & vbCrLf
      Next
   End Sub
End Module
' 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

using System;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      ulong value = 163249057;
      // Display value using default ToString method.
      outputBlock.Text += value.ToString() + "\n";
      outputBlock.Text += "\n";

      // 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)
         outputBlock.Text += String.Format("{0} format specifier: {1,16}",
                           format, value.ToString(format)) + "\n";
   }
