UInt32.ToString Method (String)

[ This article is for Windows Phone 8 developers. If you’re developing for Windows 10, see the latest documentation. ]

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

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

public string ToString(
	string format
)

Parameters

format
Type: System.String
A standard or custom numeric format string (see Remarks).

Return Value

Type: System.String
The string representation of the value of this instance as specified by format.

ExceptionCondition
FormatException

The format parameter is invalid.

The format parameter can be any valid standard numeric format specifier, or any combination of custom numeric format specifiers. If format is equal to String.Empty or is null, the return value of the current UInt32 object is formatted with the general format specifier ("G"). If format is any other value, the method throws a FormatException.

The .NET Framework provides extensive formatting support, which is described in greater detail in the following formatting topics:

The format of the returned string is determined by the NumberFormatInfo object for the current culture. Depending on the format parameter, this object controls symbols such as the group separator and the decimal point symbol in the output string. To provide formatting information for cultures other than the current culture, call the ToString(String, IFormatProvider) overload.

The following example displays a 32-bit unsigned integer value by using each standard format string and some custom format strings.


using System;
using System.Globalization;

public class Example
{
   public static void Demo(System.Windows.Controls.TextBlock outputBlock)
   {
      uint value = 2179608;
      string[] specifiers = { "G", "C", "D3", "E2", "e3", "F", 
                              "N", "P", "X", "000000.0", "#.0", 
                              "00000000;(0);**Zero**" };

      foreach (string specifier in specifiers)
         outputBlock.Text += String.Format("{0}: {1}", specifier, value.ToString(specifier)) + "\n";
   }
}
// The example displays the following output:
//       G: 2179608
//       C: $2,179,608.00
//       D3: 2179608
//       E2: 2.18E+006
//       e3: 2.180e+006
//       F: 2179608.00
//       N: 2,179,608.00
//       P: 217,960,800.00 %
//       X: 214218
//       000000.0: 2179608.0
//       #.0: 2179608.0
//       00000000;(0);**Zero**: 02179608
