C# Char ConvertToUtf32(Char, Char)

Description

Char ConvertToUtf32(Char, Char) converts the value of a UTF-16 encoded surrogate pair into a Unicode code point.

Syntax

Char.ConvertToUtf32(Char, Char) has the following syntax.


public static int ConvertToUtf32(
  char highSurrogate,
  char lowSurrogate
)

Parameters

Char.ConvertToUtf32(Char, Char) has the following parameters.

highSurrogate - A high surrogate code unit (that is, a code unit ranging from U+D800 through U+DBFF).
lowSurrogate - A low surrogate code unit (that is, a code unit ranging from U+DC00 through U+DFFF).

Returns

Char.ConvertToUtf32(Char, Char) method returns The 21-bit Unicode code point represented by the highSurrogate and lowSurrogate parameters.

Example

The following code example demonstrates the ConvertToUtf32 method.


//from   w  w  w .  ja va2 s.c o m
using System;

class Sample 
{
    public static void Main() 
    {
        int letterA = 0x0041;  //U+00041 = LATIN CAPITAL LETTER A 
        int music   = 0x1D161; //U+1D161 = MUSICAL SYMBOL SIXTEENTH NOTE 
        string s1 = "";
   
        Console.WriteLine("Create a code point from a UTF-16 encoded string.");
        letterA = Char.ConvertToUtf32(s1, 0);
        Console.Write("    1b) ");
        Show(s1);
        Console.WriteLine(" => 0x{0:X}", letterA);

    }

    private static void Show(string s){
        for (int x = 0; x < s.Length; x++){
           Console.Write("0x{0:X}{1}", 
                       (int)s[x], 
                       ((x == s.Length-1)? String.Empty : ", "));
        }
    }
}

The code above generates the following result.
