Syntax

Char.ConvertToUtf32(String, Int32) has the following syntax.


public static int ConvertToUtf32(
  string s,
  int index
)

Parameters

Char.ConvertToUtf32(String, Int32) has the following parameters.

s - A string that contains a character or surrogate pair.
index - The index position of the character or surrogate pair in s.

Example

The following code example demonstrates the ConvertToUtf32.


/*w  w w  . j  a v a 2s .c om*/

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.
