This method is used to converts the specified Unicode code point into a UTF-16 encoded string.
Syntax:
public static string ConvertFromUtf32 (int utf32);
Here, utf32 is a 21-bit Unicode code point.
Return Value: This method returns a string consisting of one Char object or a surrogate pair of Char objects equivalent to the code point specified by the utf32 parameter.
Exception: This method returns the ArgumentOutOfRangeException if utf32 is not a valid 21-bit Unicode code point ranging from U+0 through U+10FFFF, excluding the surrogate pair range from U+D800 through U+DFFF.
Below programs illustrate the use of Char.ConvertFromUtf32(Int32) Method:
Example 1:
// C# program to demonstrate // Char.ConvertFromUtf32(Int32) // Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// declaring and initializing
// int variablewith 21 bit
// unicode
int utf = 0x0042;
// getting the value
// using ConvertFromUtf32()
string value = Char.ConvertFromUtf32(utf);
// Display the value
Console.WriteLine( "value is {0}" , value);
}
catch (ArgumentOutOfRangeException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
} |
value is B
Example 2: For ArgumentOutOfRangeException
// C# program to demonstrate // Char.ConvertFromUtf32(Int32) // Method using System;
using System.Globalization;
class GFG {
// Main Method
public static void Main()
{
try {
// declaring and initializing
// int variable with 21 bit
// unicode
int utf = 0x11FFFF;
// getting the value
// using ConvertFromUtf32()
Console.WriteLine( "0x11FFFF is exceeding the limit" );
string value = Char.ConvertFromUtf32(utf);
// Display the value
Console.WriteLine( "value is {0}" , value);
}
catch (ArgumentOutOfRangeException e) {
Console.Write( "Exception Thrown: " );
Console.Write( "{0}" , e.GetType(), e.Message);
}
}
} |
0x11FFFF is exceeding the limit Exception Thrown: System.ArgumentOutOfRangeException
