Converts the value of the specified 64-bit unsigned integer to its equivalent string representation, using the specified culture-specific formatting information.

This API is not CLS-compliant. 

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

'Declaration
<CLSCompliantAttribute(False)> _
Public Shared Function ToString ( _
	value As ULong, _
	provider As IFormatProvider _
) As String

Parameters

value
Type: System.UInt64

The 64-bit unsigned 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 UInt64.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(UInt64, IFormatProvider) method to convert an unsigned long integer value to its equivalent string representation. The conversion uses both the invariant culture and the custom NumberFormatInfo object. The output indicates that this formatting information is not used, because by default the "G" format specifier does not include a positive sign with positive values.

Dim number As ULong = UInt64.MaxValue
Dim nfi As New System.Globalization.NumberFormatInfo()
nfi.NegativeSign = "~"
nfi.PositiveSign = "!"

Console.WriteLine("{0,-12}  -->  {1,12}", _
                  Convert.ToString(number, System.Globalization.CultureInfo.InvariantCulture), _
                  Convert.ToString(number, nfi))
' The example displays the following output: 
'    18446744073709551615  -->  18446744073709551615
