UInt64.ToString Method (IFormatProvider)
Converts the numeric value of this instance to its equivalent string representation using the specified culture-specific format information.
Assembly: mscorlib (in mscorlib.dll)
Parameters
- provider
-
Type:
System.IFormatProvider
An object that supplies culture-specific formatting information.
Return Value
Type: System.StringThe string representation of the value of this instance, consisting of a sequence of digits ranging from 0 to 9, without a sign or leading zeros.
Implements
IConvertible.ToString(IFormatProvider)The ToString(IFormatProvider) method formats a UInt64 value in the default ("G", or general) format by using the NumberFormatInfo object of a specified culture. If you want to specify a different format or the current culture, use the other overloads of the ToString method, as follows:
To use format | For culture | Use the overload |
|---|---|---|
Default ("G") format | Default (current) culture | |
A specific format | Default (current) culture | |
A specific format | A specific culture |
The provider parameter is an IFormatProvider implementation. Its GetFormat method returns a NumberFormatInfo object that provides culture-specific formatting information. However, none of the properties of the NumberFormatInfo are used when formatting with the general numeric format specifier ("G").
The following example formats a 64-bit signed integer value by using several format providers, including one for the invariant culture. The output from the example illustrates that the formatted string returned by the ToString(IFormatProvider) method is the same regardless of the format provider.
using System; using System.Globalization; public class Example { public static void Main() { // Define an array of CultureInfo objects. CultureInfo[] ci = { new CultureInfo("en-US"), new CultureInfo("fr-FR"), CultureInfo.InvariantCulture }; ulong value = 18709243; Console.WriteLine(" {0,12} {1,12} {2,12}", GetName(ci[0]), GetName(ci[1]), GetName(ci[2])); Console.WriteLine(" {0,12} {1,12} {2,12}", value.ToString(ci[0]), value.ToString(ci[1]), value.ToString(ci[2])); } private static string GetName(CultureInfo ci) { if (ci.Equals(CultureInfo.InvariantCulture)) return "Invariant"; else return ci.Name; } } // The example displays the following output: // en-US fr-FR Invariant // 18709243 18709243 18709243
