C# UInt16 Parse(String, NumberStyles)

Description

UInt16 Parse(String, NumberStyles) converts the string representation of a number in a specified style to its 16-bit unsigned integer equivalent.

Syntax

UInt16.Parse(String, NumberStyles) has the following syntax.


[CLSCompliantAttribute(false)]//from www  .  j  a va2  s  .  c om
public static ushort Parse(
  string s,
  NumberStyles style
)

Parameters

UInt16.Parse(String, NumberStyles) has the following parameters.

s - A string that represents 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 NumberStyles.Integer.

Returns

UInt16.Parse(String, NumberStyles) method returns A 16-bit unsigned integer equivalent to the number specified in s.

Example


using System;/*from w w w.  j ava 2s.  c o  m*/
using System.Globalization;

public class Example
{
   public static void Main()
   {
      string[] values = { " 123 ", "1,234", "(0)", "1234+", " + 234 ", " +234 ", "1234.0", "1e03", "1234.0e-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)
      {
         Console.WriteLine("Attempting to convert '{0}':", value);
         foreach (NumberStyles style in styles)
         {
            try {
               ushort number = UInt16.Parse(value, style);
               Console.WriteLine("   {0}: {1}", style, number);
            }   
            catch (FormatException) {
               Console.WriteLine("   {0}: Bad Format", style);
            }
         }
         Console.WriteLine();
      }
   }
}

The code above generates the following result.
