C# Int32 Parse(String, NumberStyles)

Description

Int32 Parse(String, NumberStyles) converts the string representation of a number in a specified style to its 32-bit signed integer equivalent.

Syntax

Int32.Parse(String, NumberStyles) has the following syntax.


public static int Parse(
  string s,
  NumberStyles style
)

Parameters

Int32.Parse(String, NumberStyles) has the following parameters.

s - A string containing a number to convert.
style - A bitwise combination of the enumeration values that indicates the style elements that can be present in s. A typical value to specify is Integer.

Returns

Int32.Parse(String, NumberStyles) method returns A 32-bit signed integer equivalent to the number specified in s.

Example

The following example uses the Int32.Parse(String, NumberStyles) method to parse the string representations of several Int32 values.


using System;/*  w w w .j  av  a 2  s.com*/
using System.Globalization;

public class ParseInt32
{
   public static void Main()
   {
      Convert("14.0", NumberStyles.AllowDecimalPoint);
      Convert("14.9", NumberStyles.AllowDecimalPoint);
      Convert(" $12,345,678.92", NumberStyles.AllowCurrencySymbol |
                                 NumberStyles.Number);
      Convert("103E06", NumberStyles.AllowExponent);
      Convert("-1,234,567", NumberStyles.AllowThousands);
      Convert("(1,234,567)", NumberStyles.AllowThousands |
                             NumberStyles.AllowParentheses);
   }

   private static void Convert(string value, NumberStyles style)
   {
      try
      {
         int number = Int32.Parse(value, style);
         Console.WriteLine("Converted '{0}' to {1}.", value, number);
      }
      catch (FormatException)
      {
         Console.WriteLine("Unable to convert '{0}'.", value);
      }
      catch (OverflowException)
      {
         Console.WriteLine("'{0}' is out of range of the Int32 type.", value);   
      }
   }
}

The code above generates the following result.
