Syntax

Decimal.Parse(String, NumberStyles, IFormatProvider) has the following syntax.


public static decimal Parse(
  string s,/* ww  w. ja v  a  2 s.  c  o m*/
  NumberStyles style,
  IFormatProvider provider
)

Parameters

Decimal.Parse(String, NumberStyles, IFormatProvider) has the following parameters.

s - The string representation of the number to convert.
style - A bitwise combination of NumberStyles values that indicates the style elements that can be present in s. A typical value to specify is Number.
provider - An IFormatProvider object that supplies culture-specific information about the format of s.

Returns

Decimal.Parse(String, NumberStyles, IFormatProvider) method returns The Decimal number equivalent to the number contained in s as specified by style and provider.

Example

The following example uses a variety of style and provider parameters to parse the string representations of Decimal values.


using System;//  w ww .java2  s.c  o m
using System.Globalization;
public class MainClass{
  public static void Main(String[] argv){  
    string value;
    decimal number;
    NumberStyles style;
    CultureInfo provider;
    
    // Parse string using "." as the thousands separator 
    // and " " as the decimal separator. 
    value = "123 456,12";
    style = NumberStyles.AllowDecimalPoint | NumberStyles.AllowThousands;
    provider = new CultureInfo("fr-FR");
    
    number = Decimal.Parse(value, style, provider);  
    System.Console.WriteLine("'{0}' converted to {1}.", value, number);
    
    number = Decimal.Parse(value, style, CultureInfo.InvariantCulture);  
    System.Console.WriteLine("'{0}' converted to {1}.", value, number);
    
    // Parse string using "$" as the currency symbol for en-GB and  
    // en-us cultures. 
    value = "$6,543.51";
    style = NumberStyles.Number | NumberStyles.AllowCurrencySymbol;
    provider = new CultureInfo("en-GB");
    
    number = Decimal.Parse(value, style, provider);  
    System.Console.WriteLine("'{0}' converted to {1}.", value, number);
    
    
    provider = new CultureInfo("en-US");
    number = Decimal.Parse(value, style, provider);  
    System.Console.WriteLine("'{0}' converted to {1}.", value, number);

  }
}

The code above generates the following result.
