C# Convert ToSByte(String, Int32)

Description

Convert ToSByte(String, Int32) converts the string representation of a number in a specified base to an equivalent 8-bit signed integer.

Syntax

Convert.ToSByte(String, Int32) has the following syntax.


[CLSCompliantAttribute(false)]// w w w.  java2  s. co m
public static sbyte ToSByte(
  string value,
  int fromBase
)

Parameters

Convert.ToSByte(String, Int32) has the following parameters.

value - A string that contains the number to convert.
fromBase - The base of the number in value, which must be 2, 8, 10, or 16.

Returns

Convert.ToSByte(String, Int32) method returns An 8-bit signed integer that is equivalent to the number in value, or 0 (zero) if value is null.

Example

The following example attempts to interpret the elements in a string array as the binary, octal, and hexadecimal representation of numeric values in order to convert them to unsigned bytes.


using System;/* w  ww  .java 2  s  .c  o  m*/

public class Example
{
   public static void Main()
   {
      int[] baseValues = { 2, 8, 16};
      string[] values = { "FF", "81", "03", "11", "8F", "01", "1C", "111", 
                          "123", "18A" }; 

      // Convert to each supported base. 
      foreach (int baseValue in baseValues)
      {
         Console.WriteLine("Converting strings in base {0}:", baseValue);
         foreach (string value in values)
         {
            Console.Write("   '{0,-5}  -->  ", value + "'");
            try {
               Console.WriteLine(Convert.ToSByte(value, baseValue));
            }   
            catch (FormatException) {
               Console.WriteLine("Bad Format");
            }   
            catch (OverflowException) {
               Console.WriteLine("Out of Range");
            }
         }
         Console.WriteLine();
      }
   }
}

The code above generates the following result.
