C# SByte Parse(String, IFormatProvider)

Description

SByte Parse(String, IFormatProvider) converts the string representation of a number in a specified culture-specific format to its 8-bit signed integer equivalent.

Syntax

SByte.Parse(String, IFormatProvider) has the following syntax.


[CLSCompliantAttribute(false)]/*from  w  ww. j a  v  a2 s.c  o m*/
public static sbyte Parse(
  string s,
  IFormatProvider provider
)

Parameters

SByte.Parse(String, IFormatProvider) has the following parameters.

s - A string that represents a number to convert. The string is interpreted using the NumberStyles.Integer style.
provider - An object that supplies culture-specific formatting information about s. If provider is null, the thread current culture is used.

Returns

SByte.Parse(String, IFormatProvider) method returns An 8-bit signed integer that is equivalent to the number specified in s.

Example

The following example defines a custom NumberFormatInfo object that defines the tilde (~) as the negative sign.


//from   w ww .  jav  a 2s . co m
using System;
using System.Globalization;

public class Example
{
   public static void Main()
   {
      NumberFormatInfo nf = new NumberFormatInfo();
      nf.NegativeSign = "~"; 

      string[] values = { "-103", "+12", "~16", "  1", "~255" };
      IFormatProvider[] providers = { nf, CultureInfo.InvariantCulture };

      foreach (IFormatProvider provider in providers)
      {
         Console.WriteLine("Conversions using {0}:", ((object) provider).GetType().Name);
         foreach (string value in values)
         {
            try {
               Console.WriteLine("   Converted '{0}' to {1}.", 
                                 value, SByte.Parse(value, provider));
            }                     
            catch (FormatException) {
               Console.WriteLine("   Unable to parse '{0}'.", value);   
            }
            catch (OverflowException) {
               Console.WriteLine("   '{0}' is out of range of the SByte type.", value);         
            }
         }
      }      
   }
}

The code above generates the following result.
