C# UInt32 Parse(String, NumberStyles)

Description

UInt32 Parse(String, NumberStyles) converts the string representation of a number in a specified style to its 32-bit unsigned integer equivalent.

Syntax

UInt32.Parse(String, NumberStyles) has the following syntax.


[CLSCompliantAttribute(false)]/*  w w w.j a  va 2 s . co  m*/
public static uint Parse(
  string s,
  NumberStyles style
)

Parameters

UInt32.Parse(String, NumberStyles) has the following parameters.

s - A string representing the number to convert. The string is interpreted by using the style specified by the style parameter.
style - A bitwise combination of the enumeration values that specify the permitted format of s. A typical value to specify is Integer.

Returns

UInt32.Parse(String, NumberStyles) method returns A 32-bit unsigned integer equivalent to the number specified in s.

Example

The following example tries to parse each element in a string array by using a number of NumberStyles values.


using System;//from   w w  w .jav  a2  s  .co m
using System.Globalization;

public class Example
{
   public static void Main()
   {
      string[] values= { " 223423 ", "1,234,234", "(0)", "12342+", " + 22349 ", 
                         " +22349 ", "123423.00", "1e03ff", "23423.0e-2" };
      NumberStyles whitespace =  NumberStyles.AllowLeadingWhite | NumberStyles.AllowTrailingWhite;
      NumberStyles[] styles= { NumberStyles.None, whitespace, 
                               NumberStyles.AllowLeadingSign | NumberStyles.AllowTrailingSign | whitespace, 
                               NumberStyles.AllowThousands | NumberStyles.AllowCurrencySymbol, 
                               NumberStyles.AllowExponent | NumberStyles.AllowDecimalPoint };

      foreach (string value in values)
      {
         foreach (NumberStyles style in styles)
         {
            try {
               uint number = UInt32.Parse(value, style);
               Console.WriteLine("   {0}: {1}", style, number);
            }   
            catch (FormatException) {
               Console.WriteLine("   {0}: Bad Format", style);
            }   
            catch (OverflowException)
            {
               Console.WriteLine("   {0}: Overflow", value);         
            }         
         }
      }
   }
}

The code above generates the following result.
