Char.ConvertToUtf32(String, Int32) Method in C#

The Char.ConvertToUtf32(String, Int32) method in C# is used to convert the value of a UTF-16 encoded character or surrogate pair at a specified position in a string into a Unicode code point.

Syntax

Following is the syntax −

public static int ConvertToUtf32 (string str, int index);

Above, str is the string that contains a character or surrogate pair. The index parameter is the index position of the character or surrogate pair in str.

Example

Let us now see an example to implement the Char.ConvertToUtf32(String, Int32) method −

using System;
public class Demo {
   public static void Main(){
      int utf = 0x046;
      string str = Char.ConvertFromUtf32(utf);
      Console.WriteLine("Final Value = "+str);
      int res = Char.ConvertToUtf32(str, 0);
      Console.WriteLine("Actual Value = 0x{0:X}", res);
   }
}

Output

This will produce the following output −

Final Value = F
Actual Value = 0x46

Example

Let us now see another example −

using System;
public class Demo {
   public static void Main(){
      int utf = 0x057;
      string str = Char.ConvertFromUtf32(utf);
      Console.WriteLine("Final Value = "+str);
      int res = Char.ConvertToUtf32(str, 0);
      Console.WriteLine("Actual Value = 0x{0:X}", res);
   }
}

Output

This will produce the following output −

Final Value = W
Actual Value = 0x57
