是否有编程方法来识别c#保留字？

using System;
using System.Linq;
using System.Reflection;
using System.Collections.Generic;

public class Program
{
    public static void Main()
    {
        string input = "int"; // 要检查的字符串

        if (IsReservedKeyword(input))
        {
            Console.WriteLine("输入的字符串是C#的保留字。");
        }
        else
        {
            Console.WriteLine("输入的字符串不是C#的保留字。");
        }
    }

    public static bool IsReservedKeyword(string input)
    {
        var reservedKeywords = typeof(Program).GetTypeInfo().Assembly.GetTypes()
            .SelectMany(t => t.GetMethods(BindingFlags.Public | BindingFlags.Static))
            .Where(m => m.GetCustomAttributes(typeof(System.Runtime.CompilerServices.CompilerGeneratedAttribute), false).Length == 0)
            .Select(m => m.Name)
            .Distinct()
            .ToList();

        return reservedKeywords.Contains(input);
    }
}
