``````char testChar = 'e';
if ( Uri::IsHexDigit( testChar ) == true )
{
Console::WriteLine( "'{0}' is the hexadecimal representation of {1}",
testChar, Uri::FromHex( testChar ) );
}
else
{
Console::WriteLine( "'{0}' is not a hex character", testChar );
}

String^ returnString = Uri::HexEscape( testChar );
Console::WriteLine( "The hexadecimal value of '{0}' is {1}", testChar, returnString );
``````
``````char  testChar = 'e';
if (Uri.IsHexDigit(testChar) == true)
Console.WriteLine("'{0}' is the hexadecimal representation of {1}", testChar, Uri.FromHex(testChar));
else
Console.WriteLine("'{0}' is not a hexadecimal character", testChar);

string returnString = Uri.HexEscape(testChar);
Console.WriteLine("The hexadecimal value of '{0}' is {1}", testChar, returnString);
``````
``````Dim testChar As Char = "e"c
If Uri.IsHexDigit(testChar) = True Then
Console.WriteLine("'{0}' is the hexadecimal representation of {1}", testChar, Uri.FromHex(testChar))
Else
Console.WriteLine("'{0}' is not a hexadecimal character", testChar)
End If
Dim returnString As String = Uri.HexEscape(testChar)
Console.WriteLine("The hexadecimal value of '{0}' is {1}", testChar, returnString)
``````
