这是您在csharp中正确编码html textarea的方式吗？

using System;
using System.Web;

class Program
{
    static void Main()
    {
        string input = "<script>alert('XSS attack');</script>";
        string encodedInput = HttpUtility.HtmlEncode(input);
        Console.WriteLine(encodedInput);
    }
}

<script>alert('XSS attack');</script>
